Goettingen-CODATA pre-RDA symposium: The critical role of university RDM infrastructure in transforming data to knowledge
Description:
All over the world universities and libraries have started the task of developing research data services. Ideally such initiatives aim to result in a complete service portfolio covering the entire research lifecycle: Support in writing proposals and data management plans, repository infrastructures for the storage of data, support in publishing data, assignment of persistent identifiers, lecturing in data management, etc. This broad scope means that such services are often seen as requiring a joint effort from from university, library, IT center, faculties and other stakeholders. Currently nowhere in the world such a complete support scenario has been established. It is timely for actors in the various dimensions of such initiatives internationally to share their experiences, research and insights. In this symposium we will explore the topic and hear research papers, practice papers and lightening talks from organisations that have started to offer such services in whole or in part on their campus. The symposium will provide a forum for universities and libraries to share their experience and to learn from each other. The symposium will take place in Göttingen from 18-20 March 2018: it is a collaboration between the University of Göttingen and CODATA and is intended as a precursor event to the RDA plenary meeting in Berlin on 21-23 March 2018.

Xinformatics 2018
Description:
This course will introduce informatics, each of its components and ground the material that students will learn in discipline areas by coursework and project assignments. In the last 2-3 years, Informatics has attained greater visibility across a broad range of disciplines, especially in light of great successes in bio- and biomedical-informatics and significant challenges in the explosion of data and information resources. Xinformatics is intended to provide both the common informatics knowledge as well as how it is implemented in specific disciplines, e.g. X=astro, geo, chem, etc. Informatics' theoretical basis arises from information science, cognitive science, social science, library science as well as computer science. As such, it aggregates these studies and adds both the practice of information processing, and the engineering of information systems.

TWed Discussion: Knowledge Graph Engineering with Satoru
Description:
TWed Talk: Weds, 27 Sep (6p *AE 217*)
TITLE: "Knowledge Graph Engineering with Satoru"
LEADER: Jim McCusker
VIDEO: TWed video streams
EVENT: Youtube
KEYWORDS: Semantalytics, Knowledge Graphs, Semantic Web, RDF, Data Science

Knowledge graphs provide a powerful basis for data science, enabling researchers to more naturally and effectively leverage the semantics of domain science in all aspects of the data analytic workflow. In this talk Jim McCusker, Director of Data Operations for Tetherless World Constellation and the architect of Satoru, will discuss how this powerful new framework makes the construction and application of knowledge graphs more accessible to domain scientists.

NOTE: This talk is highly relevant for several of the current projects in Data Analytics Research Lab (Fall 2017); DARL students are strongly encouraged to attend. We are holding this TWed in the Data INCITE Lab (AE217) to make more space available.

DESCRIPTION: Satoru is a nano-scale knowledge graph publishing, management, and analysis framework. Satoru aims to support domain-aware management and curation of knowledge from many different sources. Its primary goal is to enable creation of useful domain- and data-driven knowledge graphs. Knowledge can be contributed and managed through direct user interaction, statistical analysis, or data ingestion from many different kinds of data sources. Every contribution to the knowledge graph is managed as a separate entity so that its provenance (publication status, attribution, and justification) is transparent and can be managed and used.

BIO: Jim McCusker is Director of Data Operations for Tetherless World Constellation at RPI and is the architect for Satoru. Jim specializes in the use of knowledge graphs in biomedical research, most notably "Finding melanoma drugs through a probabilistic knowledge graph." He has worked as a software developer for more than a decade in bioinformatics, high performance computing, data mining, natural language processing, and supply chain auditing.

Plan to join us this WEDS, 03 MAY (6p) for a very special TWed as the Tetherless World Constellation holds its end-of-term Graduate Research "Lightning Talks" TWed session. This special TWed is a great way for the TWC community to learn of the wide range of amazing research happening at the Tetherless World, and "a good time is had by all!"

BACKGROUND: Lightning talks are VERY short --- approx. 2 minute! --- summaries by our students of current research work, with no NO SLIDES and only brief "crib notes."

"The point (of a lightning talk) is to make a point, and explain it as quickly (and clearly) as possible. That's it..." http://bit.ly/AC6jok Don't caught up in the whole idea of providing background information or explaining other issues.

STUDENTS: See this helpful guide BUT remember that there will be NO SLIDES for your talk; lightning talks are about YOU clearly describing YOUR work.

EVENT: YouTube
KEYWORDS: Machine Learning, Computer Vision and Pattern Recognition; Neural and Evolutionary Computing

Please join us next Weds, (26 Apr, 6p Winslow 1140) as TWC Ph.D. student Matt Klawonn leads us in a discussion of an exciting new area of machine learning known as Generative Adversarial Networks (GANs). One well-known application of GANs has been the creation of photorealistic images.

DESCRIPTION: According to Yann LeCun, "There are many interesting recent developments in deep learning ... The most important one, in my opinion, is adversarial training (also called GANs for Generative Adversarial Networks). This, and the variations that are now being proposed is the most interesting idea in the last 10 years in ML, in my opinion." In this talk we will introduce GANs, starting with some theory and moving to implementation tips and techniques. We will then take a look at some GAN demonstrations and code, moving from image to sequence generation.

BIO: Matt Klawonn is a third-year PhD student working under adviser Jim Hendler in various deep learning areas. His most recent project, one which he hopes to turn into a thesis, involves the use of GANs to create knowledge graphs from images.

LEADER: Benno Lee
VIDEO: TWed video streams
EVENT: YouTube

Please join us next Weds (19 Apr, 6p Winslow 1140) as TWC Ph.D. student Benno Lee leads us in a discussion of his research exploring novel approaches to representing the versioning of datasets.

DESCRIPTION: With the proliferation of digital data gathering, data sets rarely remain unchanged through their lifespans. Whether due to correcting errors or updated algorithms, data often needs to be republished. This leads to a demand for the means to identify and communicate about different iterations of the same set of data. The current means of this discussion falls under data provenance, but perhaps a more detailed and valuable discussion may be had with the vocabulary and concepts of versioning. This talk will focus on a linked data model which looks at a prospective data relationship, publishing those relationships in a human and machine readable change log, and beginning the discussion of measuring change.

Please join us Weds (5 Apr, 6p Winslow 1140) as TWC DirDataOps Jim McCusker leads us in a practical and revealing exploration of the deeper mysteries of SPARQL, the protocol and query language without which our lives would be more difficult!

DESCRIPTION: SPARQL is much more that basic graph patterns. It's the only query language that lets you combine advanced graph traversal, dynamic database federation, dynamic data segmentation (using named graphs), subqueries, data and knowledge introspection, and inefficient filtering all into a single query. Learn how to do these things (and why you might not always want to) at this week's TWed Talk. We will be querying DBpedia and bringing it to it's knees within 20 minutes. We might talk a bit about how to query nanopublications in interesting ways using SPARQL. Learn about compositional design, and why you might want to be careful with that.

NOTE! All TWC grad students and URPs need to learn SPARQL! If you've been told you need to learn SPARQL, the web tutorials aren't enough; this talk is "required reading."

BIO: BIO: Jim McCusker, PhD is a relic of a bygone era, when graphs were still unnamed and grad students learned query languages straight from the W3C specs.

TITLE: "Using Semantic Data Dictionaries for Semantic Data Conversion in SETLr"
LEADER: Katie Chastain
VIDEO: TWed video streams
EVENT: YouTube
KEYWORDS: Linked Data, Semantic Web, SETLr

Please join us this Weds (29 Mar, 6p Winslow 1140) as TWC PhD student Katie Chastain leads us in a tour-de-force discussion of the challenges presented when including data dictionaries and codebooks in knowledge graphs, and the use of SETLr to slay such dragons. Katie's talk will include a very brief review of SETLr for noobies...

DESCRIPTION: Conversion of tabular data into linked data is a daunting task for many projects, where hand-crafting conversion parameters is not a scaleable solution. After a brief (re)introduction to SETLr and its functionality and capabilities, I will present a Semantic Data Dictionary as an extension to a traditional data dictionary. I will highlight its usefulness for limiting the workload for human users in annotating implicit data structure, and then describe a "parsing" script for processing a completed SDD into a SETLr script. I can talk about potential future work for the parse script, and I invite discussion and ideas for what functionalities may be helpful to other research projects.

BIO: Katie Chastain is a Ph.D student working with Prof. McGuinness, focusing on data curation for semantic web applications. Their current research is with the Gates Foundation's Healthy Birth, Growth, and Development program, working on a relatively painless way to get the many datasets involved into linked data format for use in the cool visualizations the TWC is developing with CASE. Outside of research, their interests include '90s science fiction television, Magic the Gathering, and cooperative problem solving in a fantasy environment (aka Dungeons and Dragons).

EVENT: YouTube

Please join us Weds (01 Mar, 6p Winslow 1140) as TWC grad student Sabbir Rashid leads us in a discussion of work related to an upcoming paper, "A Community-Built and Evolved Ontology and Data Standard for Childhood Health." Sabbir will also cover HADatAc and give a quick demo on one or two CHEAR related use cases using the system.

DESCRIPTION: Sabbir will discuss some of the steps involved in the building of the CHEAR Ontology, including foundational supporting ontologies, integration of pilot proposals into the ontology, and Management and Browsing using HADatAc, which he will then demo in the context of Use Cases that depict how an Analyst may use the acquisition framework and ontology.

BIO: After graduating undergrad with a double major in Physics and Electrical Engineering, Sabbir Rashid spent a year teaching high school and another as a Systems Engineer for General Dynamics. He began graduate school in August of 2015, when he entered RPI as a Robotics student. He found himself shifting from a robotics focus to computer vision, and then from machine learning to computer and web science. By the end of the first school year he began a research assistantship under Deborah McGuinness, with whom he is conducting research into Semantic Web Technologies and transferred to the Computer Science department. Specifically, his work related to semantically annotated data, a field which will allows for the increased understanding of relationships between concepts through data. He is funded on the NIH CHEAR project, which attempts to solve important problems related to Childhood Health Exposures. His work focuses on both the data acquisition and annotation sides, which includes creating an ontology of important concepts related to child health studies, as well as tackling problems related to the ingestion and annotation of the data.

TWed discussion: Using Information Centrality for detecting systemic anomalies in large homogeneous networks
Description:
TWed Talk: Weds, 22 Feb (6p Winslow 1140)
TITLE: "Using Information Centrality for detecting systemic anomalies in large homogeneous networks"
LEADER: Nidhi Rastogi
VIDEO: TWed video streams
EVENT: YouTube

Please join us TOMORROW (Weds, 22 Feb, 6p, Winslow 1140) as TWC PdD student Nidhi Rastogi leads us in a discussion of her recent progress in performing anomaly detection in large networks using graph analytics.

DESCRIPTION: Modern networked systems are constantly under threat from systemic attacks. There has been a massive upsurge in the number of devices connected to a network as well as the associated traffic volume. This has further led to heightened awareness as well as inclusion of most potential attack vectors during system design and implementation. The impact of this remodeling can be seen in the increased amount of time required to detect various cyber attacks. Since this is an undesirable outcome, there is a need to identify gaps in existing intrusion detection systems that can be filled using novel approaches. Information Centrality based Anomaly Detector (IC-AD) identifies anomalous activities in large, homogeneous, and static networks. It labels network nodes with better vantage points for detecting network-based anomalies as central nodes and uses them for attack detection. The intuition is that since these central nodes already see a lot of information flowing through the network, they are in a good position to detect anomaly. This research first dives into the important role played by graph based anomaly detection in existing communication networks. We then introduce IC-AD as a centrality index based approach, one that belongs to the field of graph analytics. Through simulation, we demonstrate that IC-AD is able to detect anomalous behavior using central nodes, given the anomaly is systemic in nature.

BIO: Nidhi Rastogi is a Ph.D. candidate in the Computer Science Department of Rensselaer Polytechnic Institute, Troy, NY, where she is leading innovation in anomaly detection in large networks using graph analytics. She also holds a master=E2=80=99s in computer science from the University of Cincinnati. She has extensive work experience in networks at Verizon Wireless, NJ, and GE Global Research, NY. She is also committed to social good by using her skills in securing cyberspace, networks, graph analytics, machine learning, and AI.

TWed Talk: TONIGHT, Weds, 08 Feb (6p Winslow 1140)
TITLE: "Data science and the future of the built environment: Applying the work of Tetherless World to CASE's Active Modular Phytoremediation System (AMPS)"
LEADER: Josh Draper (RPI CASE)
VIDEO: TWed video streams
EVENT: YouTube

Please join us Wednesday, February 8, 2017 (6p, Winslow 1140) as we welcome a special guest speaker, Josh Draper from RPI's Center for Architecture Science and Ecology (CASE). Josh will discuss CASE's innovative collaboration with TWC centering on data science and the built environment. Special thanks to Paulo Pinheiro for arranging with Josh to give this talk!

DESCRIPTION: Data science and the future of the built environment: Applying the work of Tetherless World to CASE's Active Modular Phytoremediation System (AMPS)

Integrating green walls in buildings raises some interesting questions: How and to what degree might they improve indoor air quality (IAQ) ? How does IAQ play a role in executive function and health? What are the plants doing to the building's microbiome? How do you prevent mold spores? How do greenwalls affect the energy use of HVAC systems?

CASE, the Center for Architecture Science and Ecology, is performing studies with human subjects and greenwalls to begin to answer the above questions. Data Science plays a central role in the work helping to understand an inherently complex, integrated problem that requires a range of domain expertise to address. Working with Paulo Pinhero and the Tetherless World team, we are using Data Science to enable better analysis, provenance and integration.

Josh Draper, PI on CASE's current greenwall studies using AMPS, will discuss progress on our latest experiments and data science's emerging, critical role.

TWed Discussion: Semantic Markdown: Embedding Workflow Semantics via R Markdown
Description:
TWed Talk: Weds, 01 Feb (6p Winslow 1140)
TITLE: "Semantic Markdown: Embedding Workflow Semantics via R Markdown"
LEADER: John Erickson
VIDEO: (TWed video streams)
EVENT: You Tube
KEYWORDS: Semantic Workflows, Reproducibility, Data Analytics

Please join us this Weds (6p, Winslow 1140) as I discuss recent thoughts on using esp. R Markdown to extend the RStudio environment to enabling data analysts to directly generate and publish RDF that richly describes the semantics of their scripts. This is a possible next step towards best practices for "in situ" embedding of appropriate concepts and vocabulary from established ontologies (including ProvONE and domain ontologies) into practical workflows.

DESCRIPTION: I'll discuss new work that aims to explore extending markdown syntax (esp. R Markdown) in concert with 'knitr' to directly produce workflow markup, in a human-compatible way. One example of an outcome: An RStudio user can "knit" a markdown rendition that, instead of generating (e.g) PDF or HTML, an extension will generate RDF (TTL or JSON-LD) or HTML+RDFa. By "human readable," we mean markdown best practices will be developed that are reasonable for a data analyst to use; methods (possibly based on templates) must be developed that do not require the user to "know" RDF. Today we can create cumbersome R Markdown (Rmd) files that produce HTML+RDFa outputs with correct embedded workflow semantics, but the user must be an HTML and RDFa hacker to understand the code. Workflow reproducibility requires tools that data analysts will actually use.

This work will be an advancement of the semantic workflow work inspired by YesWorkflow, and leverages an approach using standard practices for R extensions, markdown and publication, creating a direct path for data analysts to get their workflows represented in knowledge graphs. This approach broadens the potential user base by helping to ensure their workflows and results are easier to discover, conceptually easier to understand, and therefore increasing the likelihood they will be cited, reused and reproduced.

TITLE: "Better Searching through Reformulated Queries"
LEADER: Amar Viswanathan
VIDEO: TWed video streams
EVENT: YouTube
KEYWORDS: SPARQL, Knowledge Graph, Linked Data

Do search engines always give you the right information? How long does it take to get an answer you are looking for? Would it have been better if the system 'talked' to you. Why can't we build such a system now? Please join us next Wednesday (6p, Winslow 1140) as TWC PhD Student Amar Viswanathan talks about how query reformulation can bridge the gap between systems and humans.

DESCRIPTION: This work focuses on addressing the problem of query failure using the Gricean maxim of cooperative answering as amotivating foundation. More specifically, using query reformulations that abide by data- and schema-awareness, we show that failed user queries can be given more context. We discuss the results for the same and argue that such reformulations help in providing a better interaction with the user.

BIO: Amar Viswanathan is an n-th year graduate student in the Tetherless World Constellation who has at last finished his thesis proposal. He has worked on sentiment analysis, event summarization, entity summarization and Linked Data Analysis. Currently he is focusing on query reformulation and dialog based Knowledge Graph Search.

Data Analytics 2017
Description:
Data and Information analytics extends analysis (descriptive and predictive models to obtain knowledge from data) by using insight from analyses to recommend action or to guide and communicate decision-making. Thus, analytics is not so much concerned with individual analyses or analysis steps, but with an entire methodology. The world at-large is confronted with increasingly larger and complex sets of structured/unstructured information; from sensors, instruments, and generated by computer simulations; data is "hidden" in websites, application servers, social networks and on mobile devices. As a nation, assimilating information across disparate domains (e.g., intelligence, economics, science) has the potential to provide improved capabilities for decision makers. In commerce and industry, analytics-driven enterprises are becoming mainstream. Yet, there is a shortfall in the key education skills needed to meet the growing needs. Traditional enterprises are moving toward analytics-driven approaches for core business functions. In the government and corporations, cybersecurity problems are prevalent. The investment in advanced analytics capabilities could potentially be more broadly leveraged today and greater than any prior government investments in computing. Emphasis is now placed on disruptive data and information sources on the Web and Internet: using Web Science and informatics to explore social networks, platform competition, the "long tail" and economic or resource impacts of the search for new findings. Key topics include: advanced statistical computing theory, multivariate analysis, and application of computer science courses such as data mining and machine learning and change detection by uncovering unexpected patterns in data.
  • Introduce students to relevant methods to recognize and apply quantitative algorithms, techniques and interpretation
  • To develop students' strategic thinking skills, combined with a solid technical foundation in data and model-driven decision-making.
  • Develop ability to apply critical and analytical methods to formulate and solve science, engineering, medical, and business problems
  • Students will examine real-world examples using modern cyberinfrastructure to place statistical and data-mining techniques in context, to develop data-analytic thinking, and to illustrate that proper application is as much an art as it is a science.
  • By the end of the course, students can effectively communicate analytic findings to non-specialists

Description:
To learn how to build computer understandable definitions of terms for usage in automated systems.
This course provides an introduction to ontologies, their uses, and an overview of their application in semantically enabled systems. Ontologies encode term meanings. Ontologies with their declarative encodings of meaning can be used to improve communications between people and can enable computer programs to function more effectively. They provide the foundation for clear and unambiguous interaction. Ontologies have become increasingly common on the web, and class participants will not only learn about the use of ontologies in web-based applications but how to evaluate ontologies for reuse in such applications. Participants will read relevant papers, learn how to critically review ontology papers as well as ontologies themselves, and will participate in at least one group project designing, using, and evaluating ontologies.

Stream Reasoning Workshop 2016
Description:
The continuous growth of volume, velocity and variety of data poses new challenges for their processing, especially when it has to be done in real-time or near-real time. It happens in many scenarios, such as IoT, social media analytics and smart cities: highly dynamic flows of heterogeneous data, supplied by different actors, have to be integrated and processed to create new knowledge. Reasoning techniques are a possible solution to cope with the problem of variety in the processing of these continuous streams of information. Anyway, while reasoners scale up in the classical, static domain of ontological knowledge, reasoning upon rapidly changing information has received attention only very recently. The combination of reasoning techniques with data streams gives rise to Stream Reasoning, a high impact research area that has already started to produce results that are relevant for both the semantic and data processing communities.

Moreover, an observation from the lessons learned on Stream Reasoning in these years is that the ordering of data over time is just one of the possible types of orders to harness in optimising the reasoning tasks. We perceive a trend in the community towards order-aware semantic technologies in works such as: top-k query answering techniques for Linked Data, SPARQL query answering on RDF annotated with partially ordered labels, and top-k ontological query answering in the context of Ontology Based Data Access.

The workshop aims at bringing together this growing and very active community interested in integrating stream processing, ordering and reasoning by using methods inspired by data and knowledge management.

KEYWORDS: Jupyter Notebooks, Data Science

Please join us this Wednesday (_6p_, Beta Classroom, Folsom Library) as TWC PhD students Ahmed Eleish and Anirudh Prabhu guide us on an "excellent adventure": a deep-dive into the practical application of Jupyter notebooks for conducting collaborative data science in various scientific domains.

NOTE: Ahmed and Anirudh are using this talk to test the use of the Beta Classroom (Folsom Library) for studying classroom interactions. Pizza will be served immediately outside the Beta (library lower level)

DESCRIPTION: As scientific research moves towards a data-driven paradigm, a need is developing for tools that enable the exploration, analysis, and visualization of data while being usable and accessible to users of different skill sets and disciplines. Data science is inherently an inclusive and interdisciplinary field that requires knowledge and expertise in multiple and at times non overlapping domains among which are applied mathematics, computer science, information science, and the domains that are the source of the data or study such as geology, astronomy, biology, and others. As such, users who are interested in working extensively with data may have varying skill sets and teams will most probably consist of members with different areas of expertise which raises the need for tools that allow collaborative work as a standard feature.

Jupyter Notebook (a spin-off project from IPython) is an open-source, interactive data science and scientific computing environment across 40 programming languages. Jupyter Notebook is a web application that allows users to create and share documents that contain code, equations, visualizations, and documentary text. Notebooks can be used in data cleaning and transformation, statistical modeling, machine learning, and much more. JupyterHub is a multiuser version of the notebook designed for centralized deployments in companies, university classrooms and research labs. In this TWed we will demonstrate some of the features of Jupyter Notebook and share our own experience of its use in a real-world data science effort.

BIO: Ahmed Eleish received his Master's degree in Information Technology from RPI in December 2015 and is currently pursuing a PhD in Multidisciplinary Science with research interests in Knowledge Representation, Knowledge Discovery, and Computational Linguistics. He is a member of the Deep Carbon Observatory's Data Science team and has worked with domain scientists on data-driven approaches to common research problems. Previous to joining RPI he had received his Bachelor's degree in Computer Science in Egypt where he worked in industry for 6 years, 4 of those at the Oracle Corporation.

Anirudh Prabhu is currently pursuing his PhD at Rensselaer Polytechnic Institute. His research interests include Data Modeling, Semantic E-science, and Data Visualization. He has completed his masters project under Prof. Peter Fox and holds a Masters in IT at RPI.

TWed Discussion: Demonstrating Wireless Sensor Networks using NS2
Description:
TWed Talk: Weds, 28 Sep (5:30p-6:30p, 1140 Winslow)
TITLE: "Demonstrating Wireless Sensor Networks using NS2"
LEADER: Nidhi Rastogi
VIDEO: TWed video streams
KEYWORDS: wireless networks, network simulation, information centrality, anomaly detection

Please join us next Wednesday (_5:30p_, 1140 Winslow) as TWC PhD student Nidhi Rastogi leads us in a discussion of the use of NS2 [1] as a means for simulating wireless sensor networks, and its potential application to her anomaly detection research.

This is a different, earlier time (this week only)...

DESCRIPTION: Large-scale collection of data, while a boon to modern data collection and analysis techniques, also poses a huge challenge of removing noise from the more useful data. Researchers have approached this problem through various means - machine learning of different data types, clustering those that should or shouldn't be present in the packet layer and labeling them according to their characteristics. This complements other existing techniques of reducing the amount of data to be analyzed making anomaly detection a much faster process. The goal remains to minimize data collection without compromising the quality of data collected. However, approaches to this end differ in means, application and kind of data to be analyzed - is it stored or real time. This research takes this effort forward by take a graph theoretic approach to large networks that need to be analyzed for identifying anomalies for a systemic detection of cyber attacks. It works by identifying specific nodes, known as node centralities that can monitor anomalies effectively and rapidly. Node centralities can be measured through various means and can depend on the type of flow or transfer across a network.

Nidhi's current focus is on applying principles of information centrality to anomaly detection. In this TWed Nidhi will share the latest developments in using NS2 (Network Simulator 2) to simulate wireless sensor networks, which she plans to use as a platform for demonstrating her broader research.

BIO: Ms. Nidhi Rastogi is pursuing PhD in Computer Science at RPI with research in Cyber Security of distributed systems. Dr. Jim Hendler is her adviser. Currently she is pursuing is identifying anomalous activities by using Information Centrality on simulated and real dataset (this part is for a later time) in NS2. Prior to joining RPI, Nidhi worked in the industry for four years in security and remote management of wireless devices on cellular networks at Verizon Wireless, NJ, and security of devices operating on the smart grid at Logic Technology Inc., Schenectady for the client GE Global Research Center, Niskayuna. Nidhi also has a Masters in Computer Science from the University of Cincinnati, OH where her thesis research was on improving security protocols in heterogeneous wireless networks during vertical handoff.

KEYWORDS: deep learning, cognitive computing, neuromorphic computing

Please join us Wednesday (7pm, 1140 Winslow) as TWC PhD student Matt Klawonn leads us in what promises to be a fascinating, practical introduction to deep learning using a number of different frameworks.

This is a new time (this week only)...

SUMMARY: In recent years, deep learning has exploded as a field of machine learning, having "dramatically improved the state-of-the-art in speech recognition, visual object recognition, object detection and many other domains such as drug discovery and genomics" (Lecun et al, 2015). It can be hard to separate the signal from the noise in the deep learning field, given the amount of research and news surrounding this trending area. In this talk, some of the core ideas of deep learning will be explored, along with a number of "tricks of the trade" which can prove critical when creating deep learning models. We will also provide examples of how models are implemented in practice, using code from a number of deep learning frameworks.

BIO: Matt Klawonn is a third-year PhD student working with professors Hendler and McGuinness in the areas of cognitive computing, neuromorphic computing, and ontologically based recommendation systems. His research is funded through a Department of Defense SMART scholarship.

With the availability of personal agents such as Cortana, Siri and Google Now, a world of humans and machines communicate and solve problems together in natural language seems not far away. The scene of freely chatting with HAL in “2001: A Space Odyssey” or Samantha in “Her” could happen to us within our lifetime. The question is: “Are we ready?”, and if the answer is “no”, then we want to ask: “What are the necessary technologies to make it happen? In this talk, I will first give an overview of how machine learning, natural language processing, and knowledge computing research are applied in Microsoft’s conversation as a platform efforts and then use math problem solving as an example to highlight the challenges ahead.

TWed Discussion: Remember the important things: semantic importance in stream reasoning
Description:
TWed Talk: Wed, 31 Aug (6p-7p, 1140 Winslow)
TITLE: "Remember the important things: semantic importance in stream reasoning"
LEADER: Rui Yan
VIDEO: TWed video streams
EVENT: Google Plus Event
KEYWORDS: stream reasoning, window management, semantic importance

Please join us WEDS, 31 Aug (6p, 1140 Winslow) for our first TWed Talk of the Fall 2016 season as sixth-year TWC PhD student provides an update on his stream reasoning research, with a particular focus on his recent progress in stream window management.

SUMMARY: Reasoning and querying over data streams rely on the ability to deliver a sequence of stream snapshots to the processing algorithms. These snapshots are typically provided using windows as views into streams and associated window management strategies. In this work, we explore a general notion of semantic importance that can be used for window management of RDF streaming data using semantically-aware processing algorithms. Semantic importance exploits the information in RDF streams and surrounding ontologies for ranking window data in terms of its contribution to solution mappings. We also consider how a stream window management strategy based on semantic importance could improve overall processing performance, especially as available window sizes decrease.

TWed Discussion: Implementing Data-driven Bioinformatics in SemNExt

TWed Talk: Wed, 20 Apr (6p-7p, 1140 Winslow)
TITLE: "Implementing Data-driven Bioinformatics in SemNExt"
LEADER: Spencer Norris
VIDEO: TWed video streams
EVENT: Google Events
KEYWORDS: Bioinformatics, ontology, data analytics, semantalytics

Please join us TOMORROW, WEDS, 20 Apr (6p, 1140 Winslow) as TWC undergrad superstar Spencer Norris leads us in an overview of SemNExT from the perspective of his contributions to the software infrastructure.

DESCRIPTION: Bioinformatics has benefited strongly from the incorporation of semantics in many high-profile projects, including StringDB, Ensembl, Uniprot, and others. While numerical analyses are not new in this discipline, the fusion of numerical and semantic analysis is. The Semantic Numeric Exploration Technology project, or SemNExT, aims at developing a framework that smooths the integration of semantically-enhanced datasets into mathematical models. As a motivating example, SemNExT has focused on gene expression in the cortical development cycle, feeding data from the aforementioned projects into R scripts and composing the results. However, the end goal is to build a system that can be easily generalized, regardless of the application domain. This is accomplished by abstracting dataset interaction using an object-oriented approach and dynamically applying different forms of analysis based upon mappings to an internal ontology, allowing the data to drive the analysis and not the other way around.

BIO: Spencer Norris is a third-year undergraduate working towards his B.S. in Computer Science at RPI. He joined the Tetherless World Constellation as a Sophomore and worked for the lab on campus over Summer 2015. His work is supervised by Dr. Deborah McGuinness and Ph.D. candidate Evan Patton, who originally conceived SemNExT. He will be expanding his skills in ontology engineering and semantic technologies as an intern at Mitre over Summer 2016 and hopes to pursue an advanced degree upon graduation.

TWed Discussion: Using Information Centrality for anomaly detection in large networks
Description:
TWed Talk: Wed, 06 Apr (7p-8p, 1140 Winslow)
TITLE: "Using Information Centrality for anomaly detection in large networks"
LEADER: Nidhi Rastogi
VIDEO: TWed video streams
EVENT: tbd
KEYWORDS: Information centrality, graph theory, cyber attacks

Please join us this WEDS, 06 Apr (7p, 1140 Winslow) as PhD student Nidhi Rastogi leads us in an update on her interesting research applying the concept of "information centrality" to the problem of detecting cyber attacks in large networks.

DESCRIPTION: Large-scale collection of data, while a boon to modern data collection and analysis techniques, also poses a huge challenge in removing noise from the more useful data. Researchers have approached this problem through various means - machine learning of different data types, clustering those that should or shouldn't be present in the packet layer and labeling them according to their characteristics. This complements other existing techniques of reducing the amount of data to be analyzed making anomaly detection a much faster process. The goal remains to minimize data collection without compromising the quality of data collected. However, approaches to this end differ in means, application and kind of data to be analyzed - is it stored or real time. This research takes this effort forward by taking a graph theoretic approach to large networks that need to be analyzed for identifying anomalies for a systemic detection of cyber attacks. It works by identifying specific nodes, known as node centralities that can monitor anomalies effectively and rapidly. Node centralities can be measured through various means and can depend on the type of flow or transfer across a network. Information centrality is used to sparsify the graph and compare various network fingerprints to identify anomalous behavior, thus proving that IC can be used for this purpose as well.

BIO: Ms. Nidhi Rastogi is pursuing PhD in Computer Science at RPI with research in Cyber Security of distributed systems. Dr. Jim Hendler is her adviser. Currently she is exploring malware propagation in distributed systems when it is under a targeted attack. Another topic she is pursuing is identifying anomalous activities by using graph analytics fundamentals. Prior to joining RPI, Nidhi worked in the industry for four years in security and remote management of wireless devices on cellular networks at Verizon Wireless, NJ, and security of devices operating on the smart grid at Logic Technology Inc., Schenectady for the client GE Global Research Center, Niskayuna. Nidhi also has a Masters in Computer Science from the University of Cincinnati, OH where her thesis research was on improving security protocols in heterogeneous wireless networks during vertical handoff.

TWed Discussion: Towards Liberal Information Extraction: A Study on Event Extraction
Description:
TWed Talk: Wed, 30 Mar (6p-7p, 1140 Winslow)
TITLE: "Towards Liberal Information Extraction: A Study on Event Extraction"
LEADER: Lifu Huang
VIDEO: TWed video streams
EVENT: Google Plus
KEYWORDS: Event extraction, event schemas, typing frameworks

Please join us WEDS, 30 Mar (6p, 1140 Winslow) as PhD student Lifu Huang leads us in what is sure to be an interesting discussion of part of his PhD research, extracting events and discovering event schemas from arbitrary input corpora.

SUMMARY: We propose a brand new ``Liberal" Event Extraction paradigm to extract events and discover event schemas from any input corpus simultaneously. We incorporate symbolic semantics (e.g., Abstract Meaning Representation) and distributional semantics to detect and represent rich event structures and adopt a joint typing framework to simultaneously extract types of events and argument roles and discover an event schema. Experiments on general and specific domains demonstrate that this framework can construct high-quality schemas with many event and argument role types, covering a high proportion of event types and argument roles in manually defined schemas. We also show that extraction performance using discovered schemas is comparable to supervised models trained from a large amount of data labeled according to pre-defined event types.

BIO: Lifu Huang is a second-year graduate student in Prof. Heng Ji's group. His research mainly focus on Information Extraction, Text Mining and Deep Learning. Specifically, his current research topic is Liberal Information Extraction, which aims to extract facts (entity, event, relation) and induce schema without humans in the loop and requires no training data or pre-defined schema.

Please join us WEDS, 23 Mar (6p, 1140 Winslow) as TWC PhD student Amar Viswanathan leads us in what will be an interesting discussion of his PhD research exploring query failure and his unique solution applying the Gricean maxim of "cooperative answering."

SUMMARY: Description : This work focuses on addressing the problem of query failure using the Gricean maxim of cooperative answering as a motivating foundation. More specifically, using query reformulations that abide by data- and schema-awareness, we show that user queries can be tuned to give approximate results. We discuss the results for the same and argue that such queries help in providing a better interaction with the user.

BIO: Amar Viswanathan is a fifth-year graduate student at Tetherless World Constellation under Prof. James A. Hendler. He has worked on sentiment analysis, event summarization, entity summarization and Linked Data Analysis. His current research interests include query reformulation in knowledge graphs.

KEYWORDS: Ontologies, scientific workflows, provenance, reproducability

Please join us WEDS, 09 Mar (6p, 1140 Winslow) as TWC PhD student John Sheehan leads us in a discussion of semantic workflows, the intersection of scientific workflows and semantic technologies including provenance. This work is becoming increasingly important as funding organizations such as the NIH focus on "rigor and reproducability" in grant applications

SUMMARY: This TWed talk will share our work in leveraging semantic technologies to capture the provenance of scientific workflows. It will discuss existing workflow management systems including YesWorkflow, a tool that enables workflow and provenance metadata to be captured by directly annotating workflow scripts in languages and tools such as Python, R, and MATLAB. Retrospective provenance consists of data dependencies captured at the time the script is run, whereas prospective provenance can capture the methods by which results are obtained. Workflow systems including YesWorkflow can support both forms of provenance. We will then explore how YesWorkflow can be extended to utilize Semantic technologies including RDF, SPARQL, and PROV-O as an alternative representation of the workflow and its provenance. Our initial focus is capturing prospective provenance from an example Python script to demonstrate these new features of YesWorkflow. Ultimately this effort may help scientists to better share and leverage each other's workflows by capturing and matching the meaning behind them.

BIO: John Sheehan is a 2nd Year Computer Science PhD student working with Prof. McGuinness. His research interests are in Healthcare Informatics and medical applications of semantic technologies.

Semantic importance in cache-enabled stream reasoning systems
Description:
TWed Talk: TONIGHT, Wed, 10 Feb (6p-7p, 1140 Winslow)
TITLE: "Semantic importance in cache-enabled stream reasoning systems"
LEADER: Rui Yan
VIDEO: TWed video streams
EVENT: Google Event
KEYWORDS: Stream reasoning, ontology, question answering

Please join us, TONIGHT, WEDS, 10 Feb (6p, 1140 Winslow) as Rui Yan leads us in a discussion of his interesting recent work on creating a cache-enabled, order-aware, ontology-based stream reasoning framework.

SUMMARY: While streaming data has become increasingly more popular in business and research communities, semantic models and processing software for streaming data have not kept pace. Traditional semantic solutions have not addressed transient data streams. Semantic web languages (e.g., RDF, OWL) have typically addressed static data settings and linked data approaches have predominantly addressed static or growing data repositories. Streaming data settings have some fundamental differences; in particular, data are consumed on the fly and data may expire.

In this talk Rui will describe a cache-enabled, order-aware, ontology- based stream reasoning framework. This framework consumes RDF streams with expiration timestamps assigned by the streaming source, utilizing both arrival and expiration timestamps in its cache eviction policies. In addition, Rui introduces the notion of "semantic importance" which aims to address the relevance of data to the expected reasoning, thus enabling the eviction algorithms to be more context- and reasoning-aware when choosing what data to maintain for question answering. Rui evaluate this framework by implementing three different prototypes and utilizing five metrics. The trade-offs of deploying the proposed framework are also discussed.

TWed Discussion: An Immersive Field Trip to Experience The Campfire
Description:
TWed Talk: TODAY, 27 Jan (6p-7p, EMPAC)
TITLE: "An Immersive Field Trip to Experience The Campfire"
LEADER: Eric Ameres
VIDEO: (TWed video streams)
EVENT: Google Event Page
KEYWORDS: Visualization, interaction, immersion, collaboration, awesomeness

"Something is always happening in the Tetherless World!"

Please join us TODAY, 27 Jan at 6p as EMPAC senior research engineer and TWC grad student Eric Ameres takes us on a guided tour of The Campfire, one of the first tools to be installed sat the Cognitive and Immersive Systems Laboratory at the Curtis R. Priem Experimental Media and Performing Arts Center (CISL@EMPAC), a partnership between Rensselaer Polytechnic Institute and IBM Research.

NOTE: For this "field trip," we will meet at the 8th Street entrance to Winslow approx. 5:45p Weds and walk to the CISL lab at EMPAC. We'll bring our pizzas with us ;)

SUMMARY: When we need to consider information as a group, most of us turn to a computer projector and a mouse. The world may be round, but our only digital option for exploring it in a meeting is on a flat screen. Surpassing that limitation by creating new computer interfaces that allow people to intuitively share and manipulate data would vastly expand the power of computers in collaborative decision-making situations (think business, medicine, and design).

The Campfire is a new computing interface that allows a small group of users to collaboratively consider information. The platform was developed by Eric Ameres, an EMPAC senior research engineer and Rensselaer doctoral student, and Gordon Clement, an EMPAC media systems integrator and Rensselaer graduate. As suggested by its name, the Campfire is a projection device shaped like a cylindrical fire pit, about six feet in diameter and two feet high. A wide rim surrounds the top of the cylinder, allowing users to gather around the Campfire and view data projected onto the walls and flat circular floor of the device. Related data sets or images can be projected onto different locations inside the Campfire, with the edge between the surfaces acting as a blending site.

In the last decade, Informatics has attained greater visibility across a broad range of disciplines, especially in light of great successes in bio- and biomedical-informatics and significant challenges in the explosion of data and information resources. Xinformatics is intended to provide both the common informatics knowledge as well as how it is implemented in specific disciplines, e.g. X=astro, geo, chem, urban, econ, etc. Informatics' theoretical basis arises from information science, cognitive science, social science, library science as well as computer science. As such, it aggregates these studies and adds both the practice of information processing, and the engineering of information systems. This course will introduce informatics, each of its components and ground the material that students will learn in discipline areas by coursework and project assignments.

TWed Discussion: Pragmatic Query Reformulation in Knowledge Graphs
Description:
TWed Talk: Tues, 01 Dec (7p-8p, Winslow 1140)
TITLE: "Pragmatic Query Reformulation in Knowledge Graphs"
LEADER: Amar Viswanathan
VIDEO: (TWed video streams)
EVENT: Google Plus

Please join us TUESDAY, 01 Dec (7p-8p) as TWC grad student Amar Viswanathan leads us in a discussion of his recent work with Prof. Jim Hendler and Geeth De Mel of IBM on query reformulation. Amar recently presented this work as a poster at the IBM Cognitive Computing Symposium and has submitted to WWW 2016 and AAAI-16, and will also present his early results at the AAAI-16 Doctoral Consortium.

SUMMARY: Knowledge graphs, one of the key components in the Semantic Web, are fast becoming indispensable in research for storing and retrieving information effectively. The ease of linking heterogeneous data coupled with the expressiveness to make inferences and the ability to find new knowledge without additional human has made them an invaluable resource for information intensive domains. Today researchers use a rich set of tools including NELL[1], YAGO[2], and DBpedia[3] to augment their information extraction work. However, access to readily consumable knowledge in such diverse and expressive KGs is still challenging. The rich schema is not expressed in a more intuitive and obvious way to the naive user. This results in a mismatch between the user's needs and the exposed knowledge; user intent does not always get translated to the right query interpretation to get accurate results.

Our work focuses on making KGs accessible for querying by using the Gricean maxim of cooperative answering[4] as a motivating foundation. More specifically, using query reformulations[5], data awareness, and pragmatic context, KGs can be made more responsive to user requirements and provide quality results in context. As a first step, we have developed a novel "pragmatic data aware query reformulation" that provides a constrained set of quality queries that augment the user's imprecise query. We discuss the results for the same and argue that such queries help in providing a better interaction with the user.

BIO: Amar Viswanathan is a fifth-year graduate student at Tetherless World Constellation under Prof. James A. Hendler. He has worked on sentiment analysis, event summarization, entity summarization, linked data and RDF analysis. His current research interests include query reformulation in knowledge graphs. This work focuses on augmenting user queries in a constrained network with reformulations that draw from both RDF entailment rules and data awareness.

Biography-Dependent Collaborative Entity Archiving for Slot Filling
Description:
TWed Talk: Mon, 09 Nov (12p-1p, Winslow 1140)
TITLE: "Biography-Dependent Collaborative Entity Archiving for Slot Filling"
LEADER: Yu Hong
VIDEO: TWed video streams
EVENT: Google Plus

Please join us MONDAY, 09 Nov (12p-1p) as postdoc Yu Hong leads us in a discussion of his work as a postdoc with Heng Ji on improving entity-oriented automatic relevant document acquisition. This is particularly interesting and relevant to those of us working to connect knowledge graphs representing domains of research (think: DCO, HBGDki, etc) with artifacts in digital repositories and other corpora.

SUMMARY:
Current studies on Knowledge Base Population (KBP) tasks such as slot filling show the particular importance of entity-oriented automatic relevant document acquisition. Richer, diverse and reliable relevant documents satisfy the fundamental requirement that a KBP system explores the nature of an entity, such as provenance-based background knowledge extraction (e.g., a person’s religion, origin, nation, etc.). We propose a fuzzy-to-exact matching-based collaborative archiving method as a possible solution to the bottleneck problem between comprehensiveness and definiteness of acquisition. In particular, we introduce topic modeling methodologies into profiling entity biography, so as to build a bridge between fuzzy and exact matching. We employ the topics in a small-scale high-quality relevant documents (i.e., exact matching results) to summarize the life slices of a target entity (i.e., so-called biography), while using the biography as a reliable reference material to detect new truly relevant documents from a large-scale semi-finished pseudo-feedback (i.e., fuzzy matching results). We leverage the archiving method in state-of-the-art slot filling systems. Experiments on KBP corpus show significant improvement.

DCO Data Science and Thermodynamic Data Rescue

TWed Talk: Tues, 27 Oct (6-7p, Winslow 1140)
TITLE: "DCO Data Science and Thermodynamic Data Rescue"
LEADER: Hao Zhong and Marshall Ma
VIDEO: TWed video streams
EVENT: Google Hangout

Please join us TOMORROW, Tuesday, 27 Oct (6-7p) PhD student Hao Zhong, together with associate research scientist Xiaogang (Marshall) Ma, leads us in a discussion of the current work on thermodynamic data rescue as a boundary activity of the DCO Data Science team.

SUMMARY: A huge number of legacy datasets are contained in the geoscience literature. Extracting, organizing, and reusing these datasets is valuable for many within the Earth and planetary science community. To explore methods and techniques for data rescue and management, the Deep Carbon Observatory Data Science Team and DCO Extreme Physics and Chemistry community member Mark Ghiorso identified thermodynamic datasets related to carbon, or, more specifically, datasets about the enthalpy and entropy of chemicals, as a proof of principle analysis.

The team developed a semi-automated workflow for accomplishing this. First, a domain expert collected relevant journal papers in the fields of geochemistry, mineralogy and petrology. The DCO-DS Team extracted, reviewed, and registered the datasets via the DCO Data Portal. Most of those papers were published between 1930 and 1980, and were only available as images scanned from printed copies, implying the extracting and reviewing process require huge amount to human work. The semi-automatic workflow includes steps to ensure extracted datasets are correct, and are saved in widely-used formats. There indeed are perceivable margins where in the future we may develop a fully automated extracting process and furthermore a more advanced workflow governing the whole process with more developed merits in the sense of data science.

The resulting datasets from this work are accessible in the DCO dataset browser through the Extreme Physics and Chemistry Community, or a newly developed Dataset Browser through the DCO Data Portal.

5th Workshop on Linked Science 2015— Best Practices and the Road Ahead (LISC2015)
Description:
Scientific dissemination traditionally relies heavily on scholarly articles and presentations at conferences. However in the past few years, we have seen an increasing trend towards the publication of raw research data to facilitate verification and reuse. ​Linked Science champions the process of publishing, sharing and interlinking scientific resources and data along with complete experiment context, which is critical for understanding, reusing and verifying scientific research. Semantic Web technologies provide a promising means for achieving this practice. ​In the past four Linked Science workshops, we have focused on investigating benefits of this approach. However, there is a still huge knowledge gap in understanding how to support Linked Science, especially for non­technical users who are new to this domain. To overcome this critical barrier to the adoption of the Linked Science approach, our 2015 edition proposes a focus on ​“Best Practices and the Road Ahead”, ​aiming for practical solutions that help applying Linked Science principles and open research discussions with regards to supporting this new practice. We are particularly interested in tools and workflows that could facilitate the practice of Linked Science, and investigations identifying challenges and gaps to be addressed, with a special focus on less technology­savvy users​. LISC2015 program will start with a keynote by Krzysztof Janowicz from the Department of Geography at the University of California, Santa Barbara and continue with paper/demo presentations. We will also arrange again the successful break-out groups for preparing a joint memo as the outcome of LISC2015.

SUMMARY: Nyushu (女书,literally "Women's writing") Nyushu Script is a gender-specific language which was used to record dialects in Hunan Province, South China. This language is now endangered because the last native user passed away 11 years ago. Some linguists in China are attempting to rescue and document Nyushu. However, the interpretation and translation process is slow since they have to manually segment, recognize and translate the characters and documents. In this presentation, we will show our recently accepted paper on automatic segmentation, recognition and translation of Nyushu. We hope this work can help expediting the process of documentation of Nyushu and other endangered languages as well.

BIO: Tongtao Zhang is a second year Ph.D. student from BLENDER, supervised by Professor Heng Ji. His main focus is cross-media information extraction.

LEADER: Rui Yan
VIDEO: TWed video streams
EVENT: Hangout

Please join us MONDAY, 28 Sep (11a-12p) as TWC PhD student Rui Yan leads us in a discussion of stream reasoning, a fascinating area of research that combines stream processing and semantic reasoning.

SUMMARY: Streaming data is ubiquitous on the web today. Lots of information conveyed by streaming data are of high value to research, for example, for the purpose of trend detection and anomaly detection. However, streaming data are so heterogeneous in physical formats and conceptual models that it is inconvenient to analyze them.

Existing stream processing systems are capable of processing large volume, high updating rate data, but not good at revealing hidden knowledge. However, semantic reasoning techniques are able to extract hidden knowledge out of the static knowledge base, but cannot deal with streaming data. Stream reasoning is proposed by D. E. Valle in 2009 to bridge this gap. Due to the transient nature of streaming data, stream reasoning systems are required to not only process data on the fly, but also reveal interlinks and relations among them to provide an abundant, accurate, timely and updating answers to a continuous query. An abstract model of a stream reasoning system is composed by stream processing unit (for data pre-processing and selection), reasoning unit (for mining hidden knowledge), querying unit (for graph matching in the selected data) and output unit (for outputting the results in stream).

BIO: Rui Yan is a 5th year PhD student in Tetherless World Constellation, Rensselaer Polytechnic Institute. He is under the guidance of Prof. McGuinness. He has been involved in many successful projects that aim to leverage the semantic technologies to facilitate semantic data processing and reasoning. His thesis topic will be around stream reasoning, which is an exciting yet vastly unexplored multidisciplinary research area. He has done internships in both startups (Franz Inc) and national labs (PNNL) from which he gained lots of industry and academic sights. More about Rui Yan please refer to his LinkedIn profile

TITLE: "HADataC: Human Aware Data Collection Framework"
LEADER: Paulo Pinheiro

Please join us WEDNESDAY, 09 Sep as Paulo Pinheiro leads us in an informal discussion and demonstration of the Human Aware Data Collection Framework (HADataC*) a compelling data management infrastructure that has emerged from TWC's engagement in the Jefferson Project at Lake George.

* HADataC is pronounced like "heart attack" with a strong Boston accent ;)

SUMMARY: A significant amount of time and effort is often spent organizing data before their meaning can be understood, thus enabling one to analyze the data and to infer new knowledge from them. The Human Aware Data Collection Framework (HADataC) is an infrastructure that enables combined collections of data and metadata in a way that metadata is properly and logically connected to data. By data collection we mean the process of identifying data sources, interacting with these sources to move the data from their transient state into persistent repositories, and to enable the data to be retrieved from their persistent repositories through the use of queries. HADataC data is composed of scientific measurements in support of empirical scientific activities and/or computer-generated results of model simulations in support of computational scientific activities. HADataC metadata is a rich collection of contextual knowledge about scientific activities encoded and connected to the data through the use of semantic web technologies. This rich metadata collection is thus leveraged by the HADataC infrastructure to support the following: data management; data governance in terms of privacy, access and dissemination; uncertainty management; and (big) data analytics.

BIO: Dr. Paulo Pinheiro is a Tetherless World (TW) Research Scientist. Previously, he was a Staff Scientist at the Scientific Data Management Group at Pacific Northwest National Laboratory and an Associate Professor of Computer Science at the University of Texas at El Paso. Dr. Pinheiro da Silva has more than one hundred publications in the area of data-intensive applications covering topics like provenance, semantic technology, human-computer interaction, artificial intelligence, databases and software engineering. His research has focused on innovative ways of using semantically enabled resources such as ontologies, process specifications (i.e., abstract workflows) and distributed provenance to support the management, preservation, analysis and visualization of complex data and information.

Cognitive Computing 2015
Description:
Cognitive Computing is a term being used for a new generation of artificially intelligence computers that interact with humans in new and important ways. Rather than human-machine interaction, cognitive computing is said to be leading to a new generation of human-machine collaboration, where computers help humans gain new insights i nto problems via a suite of technologies ranging from natural language to machine learning. The “coming of age” of cognitive computing was demonstrated when IBM’s Watson program beat the world’s experts at the TV gameshow Jeopardy! In this course, we will explore several types of cognitive computing architectures, including Watson, neuromorphic computing, and agent - based modeling, and try to discover, via team projects motivated by the students in the class, what, if anything, is truly new and exciting in t his technology space. Students should be willing to work in small teams on research - related projects requiring the teams to define, plan and implement their approaches.

Semantic eScience Class (Fall 2015)
Description:
Science has fully entered a new mode of operation. E-science, defined as a combination of science, informatics, computer science, cyberinfrastructure and information technology is changing the way all of these disciplines do both their individual and collaborative work.

Scientists are facing global problems of a magnitude, complexity and interdisciplinary nature that progress is limited by a trained and agile workforce.

At present, there is a lack formal training in the key cognitive and skill areas that would enable graduates to become key participants in e-science collaborations. The purpose is to teach methodologies, and provide application experience and skill-sets in an inter-disciplinary forum to students and interested participants.

As semantic technologies have been gaining momentum in various e-Science areas (for example, W3C's new interest group for semantic web health care and life science), it is important to offer semantic-based methodologies, tools, middleware to facilitate scientific knowledge modeling, logical-based hypothesis checking, semantic data integration and application composition, integrated knowledge discovery and data analyzing for different e-Science applications.

Partially influenced by the Artificial Intelligence community, the Semantic Web researchers have largely focused on formal aspects of semantic representation languages or general-purpose semantic application development, with inadequate consideration of requirements from specific science areas. On the other hand, general science researchers are growing ever more dependent on the web, but they have no coherent agenda for exploring the emerging trends on the semantic web technologies. It urgently requires the development of a multi-disciplinary field to foster the growth and development of e-Science applications based on the semantic technologies and related knowledge-based approaches.

To fill the gaps that are currently present in the integrative nature of informatics for the translation of science into requirements for the underlying and largely syntactic e-infrastructure.

TWed Discussion: Using Graph Centralities for detecting Anomalies
Description:
"There's always something happening Wednesday evenings in the Tetherless World!"

TWed Talk: Weds, 06 May (7p, Winslow 1140) TITLE: "Using Graph Centralities for detecting Anomalies" LEADER: Nidhi Rastogi VIDEO: TWed video streams Google Plus: Live Stream

Please join us NEXT WEDNESDAY, 06 May as TWC Ph.D. student Nidhi Rastogi leads us in a discussion of applying graph analytics, especially identifying node centralities, to the problem of combatting "noise" in large-scale data collection in applications such as detecting cyber attacks.

DESCRIPTION: Large-scale collection of data, while a boon to modern data collection and analysis techniques, also poses a huge challenge of removing noise from the more useful data. Researchers have approached this problem through various means - machine learning of different data types, clustering those that should or shouldn't be present in the packet layer and labeling them according to their characteristics. This complements other existing techniques of reducing the amount of data to be analyzed making anomaly detection a much faster process. The goal remains to minimize data collection without compromising the quality of data collected. However, approaches to this end differ in means, application and kind of data to be analyzed - is it stored or real time. This research takes this effort forward by take a graph theoretic approach to large networks that need to be analyzed for identifying anomalies for a systemic detection of cyber attacks. It works by identifying specific nodes, known as node centralities that can monitor anomalies effectively and rapidly. Node centralities can be measured through various means and can depend on the type of flow or transfer across a network. Our current focus is on exploring Information centrality and if can prove useful for this research.

BIO: Ms. Nidhi Rastogi is pursuing PhD in Computer Science at RPI with research in Cyber Security of distributed systems. Dr. Jim Hendler is her adviser. Currently she is exploring malware propagation in distributed systems when it is under a targeted attack. Another topic she is pursuing is identifying anomalous activities by using graph analytics fundamentals. Prior to joining RPI, Nidhi worked in the industry for four years in security and remote management of wireless devices on cellular networks at Verizon Wireless, NJ, and security of devices operating on the smart grid at Logic Technology Inc., Schenectady for the client GE Global Research Center, Niskayuna. Nidhi also has a Masters in Computer Science from the University of Cincinnati, OH where her thesis research was on improving security protocols in heterogeneous wireless networks during vertical handoff.

TWed Discussion: Down and Dirty with Cognitive Computing
Description:
"There's always something happening Wednesday evenings in the Tetherless World!"

TWed Talk: Weds, 29 Apr (7p, Winslow 1140)
TITLE: "Down and Dirty with Cognitive Computing"
LEADER: Simon Ellis
VIDEO: This event will NOT be streamed. In-person attendance is strongly encouraged
Google Plus: Limited available to TWC lab members

Please join us this WEDNESDAY, 29 Apr as TWC Ph.D. student Simon Ellis leads us in a very special, "down and dirty" discussion of the realities of cognitive computing, now and into the future! This discussion may include sensitive comments based on RPI's extensive experience with leading cognitive platforms and thus will not be broadcast.

DESCRIPTION: The term "cognitive computing" is becoming increasingly ubiquitous. Every few months, it seems, IBM announces a new research partnership, a new "next best thing" or another application for its biggest growing and most recognisable brand, Watson. But what really *is* 'cognitive computing'? Is it truly the game-breaking, world-changing system that it's made out to be? And what about IBM's "other", non-Watson-based form of 'cognitive computing', SyNAPSE, modelled on the architecture and processing system of the human brain itself?

In this discussion-driven event, we'll discuss the nature of "cognitive computing," what it can be used for --- and what it can't, or shouldn't --- where the technology might go and where it might lead, and everything and anything else that seems interesting at the time.

BIO: Simon Ellis is a 4th year PhD candidate, working with Professor Jim Hendler on cognitive computing. His research involves using a Watson-like system to play games with extremely large search spaces, such as Go, Arimaa and Bridge. (His dream is to make a computer that can play Dungeons & Dragons, mostly so he'll never have to go "looking for group".) He earned a BSc in Computer Games Software Development from the University of Bolton, UK and worked in the games industry before coming to RPI.

TWed Talk: Weds, 15 Apr (7p, Winslow 1140)
TITLE: "Exploring Scientific Data with Faceted Visualization Featuring Solr"
LEADER: Henrique Santos
VIDEO: (TWed video streams)
Google Plus: Live Stream

Please join us this Weds (15 Apr) as TWC visiting scholar Henrique Santos leads us in a hands-on introduction to Apache Solr, using real-life examples from the Jefferson Project!

DESCRIPTION: Scientific data comes from different sources and convey a plethora of different kinds of information. In this context, metadata plays a main role for the understanding of what is available. But to be able to fully explore the data, tools for storing, indexing and querying it are indispensable. Sometimes, a regular relational database may not be enough for the task, due to the size and variety of the available datasets.

In this talk, we'll cover the basics of Apache Solr, an open source search platform built on top of Apache Lucene with hands-on examples. Also, progress that have been made on Jefferson Project will be presented, which is making heavy use of Solr spatial and facet features.

BIOGRAPHY: Henrique Santos is a Ph.D. candidate from Universidade de Fortaleza, in Fortaleza, Brazil, visiting Tetherless World under the supervision of Prof. Deborah McGuinness. He currently works on the Jefferson Project, building its indexing and searching processes. For his Ph.D. studies, he is working with Prof. Vasco Furtado on integrating urban live stream data and static datasets using Semantic Web technologies to leverage the development of intelligent agents that make use of it. He earned a masters degree in Computer Science form Unifor in 2012 and a bachelors degree in Computer Science from Universidade Federal do Ceará in 2006.

INTRODUCTION In the past few decades, the field of ecology has grown from a collection of disparate researchers who collected data on their local phenomenon by hand, to large projects fueled by automated sensor networks that rely on sharing data to answer questions of extraordinary scale and complexity. Semantic technologies offer many opportunities for better data management in ecology, but also pose a challenging learning curve to already busy researchers. This talk will discuss and demonstrate a mobile application for recording semantic metadata about sensor network deployments in real time, in the field, and with no prior knowledge of semantics. This application enables more efficient and less error-prone metadata collection, and generates structured and shareable metadata with just a few QR code scans.

Twed Hackathon: Hands-on Environmental Modelling with openModeller
Description:
"There's always something happening Wednesday evenings in the Tetherless World!"

TITLE: "Hands-on Environmental Modelling with openModeller"
LEADER: Matt Klawonn
VIDEO: (TWed video streams)
Google Plus: http://bit.ly/twed_google_plus

NOTE: Next week's TWed will be a highly interactive, hands-on session in which Matt Klawonn will guide us through modelling with openModeller. PLEASE review Matt's installation instructions (below) and contact him klawom@rpi.edu if you have any questions.

INTRODUCTION: Environmental niche modelling, alternatively known as species distribution modelling, (ecological) niche modelling, predictive habitat distribution modelling, and climate envelope modelling refers to the process of using computer algorithms to predict the distribution of species in geographic space on the basis of a mathematical representation of their known distribution in environmental space." In this talk, the openModeller tool will be introduced as an open source means of creating ecological niche models. We will generate an example model based on available data and the openModeller package, and then explore techniques to visualize and programmatically use the model. Applications into other distribution models will be discussed.

INSTALLATION REQUIREMENTS: In order to use the time efficiently, plan to install the openModeller package at minimum. The openModeller package can be downloaded via http://sourceforge.net/projects/openmodeller/files/openModeller/1.5.0/

Currently, there are binaries for Windows, Mac, and rpm linux distros. If installing on a debian based distro, you will need to follow the instructions at http://openmodeller.sourceforge.net/INSTALL.html#toc17 NOTE: John has verified the Linux instructions; there is an issue using that method, wherein the package cannot locate a shared library when attempting to run openModeller. Matt will discuss the fix for this during the talk if anyone runs into it.

If you would like to visualize your results, or use them programatically, you can also install some GIS software. Matt will discuss how to use QGIS to visualize the output, and also give pointers to python modules that will let you use your output in applications. These modules are PyQGIS and GDAL, if you would like to install them ahead of time.

QGIS is available through your package manager on Linux, or downloadable for another OS (even Android supposedly, though not tested) via http://www2.qgis.org/en/site/index.html Information for downloading GDAL is available at http://www.gdal.org/

Integrating Relational Databases with the Semantic Web
Description:
Title: Integrating Relational Databases with the Semantic Web
Speaker: Dr. Juan Sequeda

Abstract:
An early vision in Computer Science was to create intelligent systems capable of reasoning on large amounts of data. Independent results in the areas of Description Logic and Relational Databases have advanced us towards this vision. Description Logic research has advanced the understanding of the tradeoff between the computational complexity of reasoning and the expressiveness of logic languages; and now underpins the Semantic Web. Database research has advanced the theory and practice of storage and management of data, embodying features such as views and recursion, which are capable of representing reasoning. Despite the independent advances, the interface between Relational Databases and Semantic Web is poorly understood.

My research revisits this vision with respect to current technology and addresses the following question: How and to what extent can Relational Databases be integrated with the Semantic Web? The thesis is that much of the existing Relational Database infrastructure can be reused to support the Semantic Web.

In this talk, I will provide an answer to the following question: Can a Relational Database be mapped to existing Semantic Web ontologies and act as a reasoner? I will present our system UltrawrapOBDA, an Ontology Based Data Access system comprising bidirectional evaluation, that is, a hybridization of query rewriting (backward chaining) and materialization (forward chaining). UltrawrapOBDA supports inheritance and transitivity.

We observe that by compiling the ontological entailments as mappings, implementing the mappings as SQL views and materializing a subset of the views; the underlying SQL optimizer is able to exploit capabilities beyond relational algebra, such as query rewriting using materialized views and SQL recursion, hence reducing the execution time of a SPARQL query. The ontology expressivity considered is not specific to a single profile, hence I will also speak to a new proposal: OWL-SQL.

I will close with a discussion on the extent that Relational Databases can integrated with the Semantic Web and open problems.

RDA Metadata And Semantics Workshop
Description:
The Metadata IG will concern itself with all aspects of metadata for research data. In particular it will attempt to coordinate the efforts of the WGs concerned with metadata to produce a coherent approach to metadata covering metadata modalities of description, restriction, navigation, provenance, preservation and the use of metadata for the purposes discovery, contextualisation, validation, analytical processing, simulation, visualisation and interoperation. It will also liaise with the other WGs especially Data Foundation and Terminology, PIDs, Standardisation of data categories and codes and Data Citation. This IG activity relates to data management policies and plans of research organisations and researchers, and to policies and standards of research funders and of research communities which may or may not be official standards.

The metadata IG will organise itself through online meetings and face-to-face meetings of members of the IG present at RDA Plenary events. It is proposed that – while membership is open to any RDA registered member – key members will be the leaders of the WGs concerned with metadata. In order to get the renovated IG working I volunteer to initiate this activity but would expect elections and handover to someone else after an initial period.

TWed Discussion: Choose Your Own Path: A Journey Down the Rabbit Hole of Privacy
Description:
TWed Talk: Weds, 18 Feb (7p, Winslow 1140)
TITLE: "Choose Your Own Path: A Journey Down the Rabbit Hole of Privacy"
LEADER (TWC): Kristine Gloria

Please join us NEXT WEDNESDAY (18 Feb) as TWC Ph.D. student Kristine Gloria leads us down the "rabbit hole" in an open discussion of the present and future of privacy!

"Choose Your Own Path: A Journey Down the Rabbit Hole of Privacy" Privacy evokes a myriad of concepts that are neither static in time or in context. For some, its traditional notion of a civil liberty is being challenged by new technologies and increased surveillance. While others, dismiss it all together as a barrier to solving larger social needs, like healthcare. It is a concept deeply intertwined in social, technical, and political implications. "It is a riddle, wrapped in a mystery, inside an enigma".

Yet, no matter your allegiance in the debate, it is clear that it is time to re-conceptualize privacy in light of our contemporary, highly-connected world. This interactive discussion will present the different paths and definitions currently in play and will ask of participants to think beyond the now. We encourage anyone interested in privacy from any level and from any perspective to join in what we hope will be a lively debate.

TWed Discussion: The Philosophy of Linked Data
Description:
"There's always something happening Wednesday evenings in the Tetherless World!"

TWed Talk: Weds, 04 Feb (7p, Winslow 1140)
TITLE: "The Philosophy of Linked Data"
LEADERS (TWC): Dominic DiFranzo

Please join us WEDNESDAY (04 Feb) for our second Spring 2015 TWed as TWC Ph.D. student Dominic DiFranzo leads us in an open discussion of "The Philosophy of Linked Data"

BACKGROUND: In "Hypertext 3.0" [1] George Landow draws on theorists such as Jacques Derrida, Roland Barthes, Gilles Deleuze, Paul de Man, and Michel Foucault, among others to argue, especially, that hypertext embodies the textual openness championed by poststructuralist theory and that hypertext enables people to develop knowledge in a non-linear, non-sequential, associative way that linear texts do not. He states that hypertext and literary theory argue that we must abandon conceptual system founded on the ideas of center, margin, hierarchy and linearity and replace them by ones of multi-linearity, nodes, links and networks.

Many parallels between computer hypertext and critical theory have many points of interest, critical theory promises to theorize hypertext and hypertext promises to embody and thereby test aspects of theory, link those concurring textuality, narrative and the roles or function of a reader and writer. Hypertext and reading hypertext clarifies many pot the most significant ideas of critical theory. Bolter point out in the course of explaining that hypertextiality embodies poststructralist conceptions of the open text. Foucault conceives of text in terms of networks and links. In the Archaeology of Knowledge, he points out that the ",frontiers of a book are never clear-cut,", because ", it is fought up in a system of references to other books, other texts, other sentences; it is a bode within a network ... a network of references"

Because readers in hypertext can easily follow links, and follow paths on their own in a easy manner, this changes the nature of reading and what is read. And this blurs the line between the reader and writer.

FOR DISCUSSION: Can Linked Data also be seen as a poststructural technology like hypertext? What does this mean for our knowledge production in linked open data, and what effect will this have on the tools and technologies we produce?

This TWed is relevant to virtually everyone at TWC; be there!

Xinformatics 2015
Description:
In the last 2-3 years, Informatics has attained greater visibility across a broad range of disciplines, especially in light of great successes in bio- and biomedical-informatics and significant challenges in the explosion of data and information resources. Xinformatics is intended to provide both the common informatics knowledge as well as how it is implemented in specific disciplines, e.g. X=astro, geo, chem, etc. Informatics' theoretical basis arises from information science, cognitive science, social science, library science as well as computer science. As such, it aggregates these studies and adds both the practice of information processing, and the engineering of information systems. This course will introduce informatics, each of its components and ground the material that students will learn in discipline areas by coursework and project assignments.
To instruct future information architects how to sustainably generate information models, designs and architectures To instruct future technologists how to understand and support essential data and information needs of a wide variety of producers and consumers For both to know tools, and requirements to properly handle data and information Will learn and be evaluated on the underpinnings of informatics, including theoretical methods, technologies and best practices.

Data Analytics 2015
Description:
Data and Information analytics extends analysis (descriptive and predictive models to obtain knowledge from data) by using insight from analyses to recommend action or to guide and communicate decision-making. Thus, analytics is not so much concerned with individual analyses or analysis steps, but with an entire methodology. The world at-large is confronted with increasingly larger and complex sets of structured/unstructured information; from sensors, instruments, and generated by computer simulations; data is "hidden" in websites, application servers, social networks and on mobile devices. As a nation, assimilating information across disparate domains (e.g., intelligence, economics, science) has the potential to provide improved capabilities for decision makers. In commerce and industry, analytics-driven enterprises are becoming mainstream. Yet, there is a shortfall in the key education skills needed to meet the growing needs. Traditional enterprises are moving toward analytics-driven approaches for core business functions. In the government and corporations, cybersecurity problems are prevalent. The investment in advanced analytics capabilities could potentially be more broadly leveraged today and greater than any prior government investments in computing. Emphasis is now placed on disruptive data and information sources on the Web and Internet: using Web Science and informatics to explore social networks, platform competition, the "long tail" and economic or resource impacts of the search for new findings. Key topics include: advanced statistical computing theory, multivariate analysis, and application of computer science courses such as data mining and machine learning and change detection by uncovering unexpected patterns in data.
• Introduce students to relevant methods to recognize and apply quantitative algorithms, techniques and interpretation • To develop students' strategic thinking skills, combined with a solid technical foundation in data and model-driven decision-making. • Develop ability to apply critical and analytical methods to formulate and solve science, engineering, medical, and business problems • Students will examine real-world examples using modern cyberinfrastructure to place statistical and data-mining techniques in context, to develop data-analytic thinking, and to illustrate that proper application is as much an art as it is a science. • By the end of the course, students can effectively communicate analytic findings to non-specialists

TWed Talk: TONIGHT, Weds, 12 Nov (7p, Winslow 1140)
TITLE: "Exploring Threat modeling using Semantic Web Technologies: A Summer Internship at Raytheon BBN Technologies"
LEADER: Nidhi Rastogi, Ph.D. Student, Tetherless World Constellation

Please join us TONIGHT (Weds, 12 Nov) as TWC Ph.D. student Nidhi Rastogi leads us in a discussion of her Summer 2014 internship at Raytheon BBN Technologies, focussing on threat modelling using Semantic Web technologies.

ABSTRACT: Threat modeling involves threat analysis of a system to identify all possible attacks when considering the overall architecture. Deploying moving target defenses (MTDs) on this system can protect it from active adversaries by changing control across multiple system dimensions in order to increase uncertainty and apparent complexity for attackers. It also reduces their window of opportunity, increases the costs of their probing and attack efforts. Quantification of the impact of deploying some of the MTDs on the system's security and overall performance can be quite useful. Semantic web tools and technology come handy when performing this interesting research. Some of my responsibilities during the internship involved modeling the system, attack surfaces and MTDs primarily using ontology based applications such as Protégé, and Topbraid. I learnt that Turtle, SPARQL, and OWL are the underlying Semantic web technologies used in these tools. The talk will cover these topics and more.

About BBN: Raytheon BBN Technologies is an American high-technology company which provides research and development services. Based next to Fresh Pond in Cambridge, Massachusetts, it is also a military contractor, primarily for DARPA.

BIO: Ms. Nidhi Rastogi is pursuing PhD in Computer Science at RPI with research in Cyber Security of distributed systems. Dr. Jim Hendler and Dr. Stacy Paterson are advising her. Currently she is exploring malware propagation in distributed systems when it is under a targeted attack.

Prior to joining RPI, Nidhi worked in the industry for four years in security and remote management of wireless devices on cellular networks at Verizon Wireless, NJ, and security of devices operating on the smart grid at Logic Technology Inc., Schenectady for the client GE Global Research Center, Niskayuna. Nidhi also has a Masters in Computer Science from the University of Cincinnati, OH where her thesis research was on improving security protocols in heterogeneous wireless networks during vertical handoff.

Please join us this Wed (05 Nov) as RPI EMPAC Sr. Research Engineer and CogSci Ph.D. student Eric Ameres blows us away with a discussion and LIVE demonstration of his work combining live, interactive coding and intelligent agents in live musical performance! Cool visuals and loud music are promised...

ABSTRACT: This talk will provide an introduction to interactive coding technologies and techniques used typically in music and performing arts (the Max coding environment from Cycling74 and Ableton's "Max for Live") along with insight into how to create simple but effective "intelligent" agents using such methods as Markov models and hidden Markov processes and chains that can not only learn and "improvise" based on rules and user input, but that provide direct feedback to their fellow collaborators, including humans and other programmed agents.

The talk will also likely include some musical performances by the agents that will be "live coded" during the presentation.

BIOGRAPHY: Eric Ameres is an Nth year (part time) PhD student in Cognitive Science and is the Sr Research Engineer at RPI's EMPAC. His interests include human/machine collaboration and creativity and the perceptual coding of data, based on probabilistic models of cognition and creativity "tuned" to human perception.

UbiKeyboard: Using sensors and muscle memory to eliminate physical keyboards
Description:

TWed Talk: Weds, 22 Oct (7p, Winslow 1140)
TITLE: "UbiKeyboard: Using sensors and muscle memory to eliminate physical keyboards"
LEADER: Yu "Momo" Chen

Please join us this Wed (22 Oct) as Tetherless Ph.D. student Yu "Momo" Chen leads us in a discussion and (possible) LIVE DEMO of some extraordinarily cool work he has been involved with in advancing gestural input technology.

ABSTRACT: As wrist-worn motion sensors become increasingly common, the opportunities for gestural input techniques, in particular the input of natural language text, have become increasingly compelling. In this paper, we present the design, implementation and evaluation of UbiKeyboard, a novel data glove which enables one-handed typing by means of inertial sensors alone. UbiKeyboard takes advantage of the fact that frequent users of a simple keyboard such as a telephone-style keypad have committed the layout to muscle memory and are able to type by touch. By tracking the relative position of the hand as it moves from memorized key to key, our system is able to do away with the physical keyboard entirely, responding to characters typed upon an imaginary keyboard within any flat, level surface. Accurate recognition of words and phrases is facilitated by the use of a language model trained on a large corpus. We have demonstrated 72% accuracy for input of individual words and 53% accuracy for input of full sentences by trained users, sufficient for supporting a variety of real- world applications.

BIOGRAPHY: Yu Chen is a fourth-year PhD student in Computer Science. His interests includes mobile sensor data analysis and context modeling using a combination of techniques such as machine learning, signal processing, language modeling etc.

TWed Talk: Automatic Summarization of Customer Log Data
Description:
"There's always something happening Wednesday evenings in the Tetherless World!"

TWed Talk: Weds, 24 Sep (7p, Winslow 1140)
TITLE: "Automatic Summarization of Customer Log Data"
Presenter: Amar Viswanathan
LEADERS: Amar Viswanathan, Ph.D. student, Tetherless World Constellation, Rensselaer Polytechnic Institute
KEYWORDS: Natural Language Processing, Watson, Question Answering

Please join us this Weds, 24 Sep in Winslow as Amar Viswanathan leads us in a review of his internship with IBM this summer, where he applied NPL principles to the practical but challenging problem of customer log data summarization!

ABSTRACT: Traditionally issues arising from IBM's Operation System Products i.e. AIX machines are referred to customer service agents who look at these issues and then try to resolve them based on their knowledge of the system. They are aided by a huge database of call logs which allow them basic querying i.e. "keyword based queries". However, it has been noticed that this database does not really provide a good set of similar documents for the query. The reason this happens is because current indices like indri or lucene or even the Question Answering System Watson, aren't able to index such documents efficiently. This happens primarily because each customer log has text that can be classified as noise. i.e. a lot of machine specific data generation, stack traces, OS dump data, file size data, file transfer data, and even text which are Operating System commands. But all of these are required for the agent to resolve the issue. Imagine if the same issue has cropped up earlier and has also been resolved. If we had an efficient querying system all it would do is tell the agent what documents had similar issues and also tell him how it was resolved. So I had to produce a different kind of summarization where I could summarize the client log data and then prepare it in such a way that it not only provides details about what kind of commands were issued and how these issues were resolved, but also tells the agent where to find the required patches if an issue was resolved. So a "from the scratch" NER system was built, which handled new entity types i.e. as opposed to the ones mentioned in the ACL challenges. This NER system's output was then used to build summaries, which in turn are in the process of being sent to QA systems like Watson. In addition the outputs of the NER phase are also in the process of being converted to Linked Data and I shall talk about how Linked Data can be effectively utilized for further analysis of Natural Language System Outputs.

BIO: Amar Viswanathan is a fourth year PhD Student in the TWC and is advised by Prof. Hendler. He works primarily on Natural Language Processing Systems and Linked Data. He is particularly interested in Question Answering Systems for Linked Data Graphs and Generating Event Summaries from Natural Language Outputs using Linked Data as a medium.

TWed Discussion: Capturing and Presenting Provenance of Global Change Research
Description:
"There's always something happening Wednesday evenings in the Tetherless World!"

TWed Talk: Weds, 17 Sep (7p, Winslow 1140) TITLE: "Capturing and Presenting Provenance of Global Change Research" Presenter: Xiaogang (Marshall) Ma LEADERS: Xiaogang (Marshall) Ma (Associate Research Scientist at Tetherless World Constellation, Rensselaer Polytechnic Institute)

Please join us TOMORROW, Weds, 17 Sep in Winslow as Marshall Ma leads us in what should be an interesting discussion on the importance of data provenance enablement in global change research and may ultimately play a role in policy and decision-making.

ABSTRACT: The topic of global change covers changes in the global environment that may alter the capacity of the Earth to sustain life and support human systems. The provenance information of global change research is important because the research findings are of great public and academic concern and are used in policy and decision-making. This talk consists of two parts. One is an introduction to the recent work on provenance enablement in information modeling and semantic prototypes for the Global Change Information System. Experience of ontology engineering with the use case-driven iterative approach developed by the Tetherless World Constellation will be presented. The other is a discussion on future works centered on the concept of scenario in global change research. A scenario is a qualitative or quantitative projection of the future. The talk will review the current works on scenario in global change research and set a context for further information modeling.

BIO: Short bio: Xiaogang (Marshall) Ma is an associate research scientist at Tetherless World Constellation, Rensselaer Polytechnic Institute. He received PhD of Earth Systems Science and GIScience from University of Twente, The Netherlands. His research interests include qualitative and quantitative modeling of complex systems in Earth and environmental sciences, data interoperability and provenance enablement through participatory approaches and semantic technologies, and exploratory visualization of spatio-temporal features in Big and Little Data.

Talk: Silk Purses from Sow’s Ears: Generating Quality Multiple Choice Questions from Ontologies
Description:
Dr. Bijan Parsia will be visiting the Tetherless World Constellation lab next week. He will be giving a talk on Monday, September 15 at 1:00pm in Winslow, Room 1140.

Short Biography
Bijan Parsia is a senior lecturer at the University of Manchester (UK) in the School of Computer Science. Bijan Parsia is a member of the Information Management Group (IMG) since May of 2006. Before that, he was a Faculty Research Associate in the Mindswap group at the University of Maryland College Park (UMCP).

Title: Silk Purses from Sow’s Ears: Generating Quality Multiple Choice Questions from Ontologies

Abstract: One promise of Knowledge Representation (KR) is that a properly designed, representationally adequate KR in a sufficiently powerful language will be reusable in many contexts for many applications beyond the original intended purpose. The classic example of this was the attempt to repurpose the early diagnostic expert system, MYCIN, into a tutoring tool (GUIDON). The key hope was that the knowledge encoded in MYCIN which was sufficient for *performing* diagnosis would be useful for *teaching* how to diagnose.

Today, the Resource Description Framework Schema (RDFS) language and the Web Ontology Language (OWL 2) are probably the most popular logic based KR languages extent with thousands of ontologies and datasets availed for a wide variety of topics with varying degrees of complexity and comprehensiveness of representation. The BioPortal community repository has a growing, actively evolving set of hundreds of ontologies focused on the life sciences. This constitutes a vast reservoir of knowledge to reuse.

In this talk, I will discuss a small piece of this puzzle, the generation of high quality Multiple Choice Questions (MCQ) from OWL ontologies. To this end, I first discuss the basic theory of MCQs, their utility, and their quality dimensions. Then I will propose a psychological grounded theory of MCQ difficulty (a key metric) base on similarity theory. Then I will discuss how we can interpret similarity in the context of logic based ontologies. Finally, I will discuss some experiments and experiences in applying all this to generating classroom ready MCQs.

TWed Talk: Weds, 27 Aug (7p, Winslow 1140) TITLE: "Complicating the Social and the Technical Sciences of the Web: Provocations from Feminist and Postcolonial Studies" LEADERS: Lindsay Poirier (Grad student, Science and Technology Studies; member, RPI Web Science Research Center)

Please join us Weds, 27 Aug in Winslow for our first TWed of the Fall 2014 term as Lindsay Poirier, an active member of our WSRC team, leads us in a discussion of how political and cultural decisions shape the Web as we know it, and the sorts of design considerations needed to produce a robust and inclusive web.

ABSTRACT:
As Web Science emerges as an interdisciplinary field, there have been laudable efforts to carve space for the social sciences to contribute to understanding web dynamics. However, in carving that space, the social component of the web is deemed distinct from computational and architectural components. My talk will complicate the distinctness of the web's social and technical aspects, showing how they not only overlap, but are in fact fully integrated. I will focus on concepts from feminist and postcolonial studies to (1) show how political and cultural decisions shape the Web as we know it and (2) draw attention to the sorts of design considerations needed to produce a robust and inclusive web.

BIO:
Lindsay Poirier is a second-year M.S./PhD student in Science and Technology Studies. Her research critically examines web architecture, information infrastructures, and computational social science methods.

GeoData 2014: Strengthening the connections, building the inter-agency network
Description:
GeoData, in the scope of EarthCube (http://earthcube.org/), refers to datasets collected and curated by the broad 'Geo' community supported by: DoE, EPA, NASA, NOAA, NSF, USDA, USGS, etc. These datasets cover subject areas including agriculture, atmospheric, solid Earth, energy and climate, environment, geospace, ocean and polar sciences. EarthCube seeks a community-driven, interoperable, geoscience-wide geoinformatics infrastructure in concert with other agencies. The GeoData workshop series aims to complement EarthCube by extending the scope of the discourse beyond the NSF-funded geoscience research community. The GeoData 2011 workshop (http://tw.rpi.edu/web/Workshop/Community/GeoData2011) provided a forum for the rich exchange of ideas, experiences and challenges focusing on three subject areas: data lifecycle, citation and integration. Many key findings and recommendations have been extracted from the detailed breakout discussions and syntheses during and after the workshop and many have been acted upon. Topical categories included: metadata, standards, standards-based tools, culture, collaboration and workforce development. GeoData 2014 takes the next steps. It begins with a review of progress in those three subject areas in recent years, and continues the focus on data lifecycle issues within inter-agency and community conversations, connecting and interacting with on-going EarthCube community activities. GeoData 2014 focuses on two subject areas: (1) Social, political and financial issues of connecting geodata within and among governmental agencies and (2) Technical issues of connecting geodata in and among governmental agencies. Each subject will be covered by an introductory panel discussion and four working breakouts. Invited participants are sought from all ‘Geo’ disciplines, and beyond: information, computer and library science, agency, academia and commercial organizations, and student to senior faculty/administrators.

The goal of the Semantic Web is to create a Web of knowledge and services in which the semantics of content is made explicit and content is linked to both other content and services novel applications allowing to combine content from heterogeneous sites in unforeseen ways and support enhanced matching between users needs and content. This network of knowledge-based functionality will weave together a large network of human knowledge, and make this knowledge machine-processable to support intelligent behaviour by machines. Creating such an interlinked Web of knowledge which spans unstructured, RDF as well as multimedia content and services requires the collaboration of many disciplines, including but not limited to: Artificial Intelligence, Natural Language Processing, Database and Information Systems, Information Retrieval, Machine Learning Multimedia, Distributed Systems, Social Networks, Web Engineering, and Web Science. These complementarities are reflected in the outline of the technical program of the ESWC 2014; in addition to the research and in-use tracks, we will feature two special tracks putting particular emphasis on inter-disciplinary research topics and areas that show the potential of exciting synergies for the future, eGovernment and Digital Libraries. ESWC 2014 will present the latest results in research, technologies and applications in its field. Besides the technical program organized over twelve tracks, the conference will feature a workshop and tutorial program, system descriptions and demos, a posters exhibition and a doctoral symposium.

TWed Talk: WebSig: A Digital Signature Framework for the Web
Description:
"There's always something happening Wednesday evenings in the Tetherless World!"

TWed Talk: Weds, 14 May (7p, Winslow 1140)
TITLE: "WebSig: A Digital Signature Framework for the Web"
LEADERS: Jim McCusker

Please join us Wednesday for the final TWed of the Spring 2014 term as TWC PhD student Jim McCusker leads us in an a discussion of Web Signature (WebSig), a new digital signature framework Jim is developing as a component of his PhD work.

ABSTRACT: Conventional digital signatures are designed to sign specific byte sequences. Further, the standard infrastructure of Public Key Cryptography does not include a mechanism for independently asserting _who_ controls the key in question. This means that any assertions about the signing agent within the signed document are not clearly defined. The link between the signer and the content must be interpreted either relative to a fixed database or via some knowledge external to the document signature. This means that any database that collects digital signatures and signed documents must either be itself trusted to faithfully record the identity of the signer (and how they relate to the document itself) or to some trusted third party that can produce interpretations of the document that relate its content to the signing agent. We put forth a web-oriented digital signature scheme called Web Signature (WebSig) that uses several existing standards and technologies to produce verifiable digital signatures where it is possible not only to identify the signer of the document using the emerging WebID standard, but also to store the resulting signatures and document contents in untrusted databases in a way that allows the content itself to be trusted, not simply one particular serialization of it.

TWed Talk: Weds, 23 Apr (7p, Winslow 1140)
TITLE: "Urban Sprawl Assessment Portal for Tetherless World Constellation"
LEADERS: ITWS Capstone Project Team One: Lakshmi Chenicheri, Aaron Tobias, Gouravjeet Singh and Jiale Sun

Please join us this Wed (23 Apr) for a very special TWed as ITWS Capstone Team One leads us in an interesting discussion AND LIVE DEMO of their Spring 2014 Capstone project, a dynamic web application for reviewing factors contributing to urban sprawl. This project was sponsored by the Web Science Research Center (WSRC) of TWC RPI.

ABSTRACT:
The team was challenged to utilize open government data to create a mobile app that would promote positive social change by helping solve a local, community problem. Based on an evaluation of available datasets and consultation with the WSRC team, ITWS Capstone Team One chose to create a portal to help a variety of stakeholders interactively review factors associated with urban sprawl. The team identified datasets provided through the New York State open data portal [1] from relevant domains such as health, environment or education; applied Semantic Web and other technologies to combine and visualize datasets in compelling ways; used agile development techniques to deliver a mobile, interactive app; and applied Web Science principles to measure the effectiveness of their solution.

To complete this challenge Team One was expected to demonstrate a practical knowledge of data structures and application development, including web application development. During the development process specific skills such as mobile app design and development, the architecture of data-driven apps, the implementation of web apps using remote visualization APIs, and knowledge of Javascript, JSON, and the Semantic Web stack (RDF, SPARQL, principles of Linked Data) were utilized.

TWeD Talk: PROV and OPeNDAP
Description:
"There's always something happening Wednesday evenings in the Tetherless World!"

TWed Talk: Weds, 16 Apr (7p, Winslow 1140) TITLE: "PROV and OPeNDAP" LEADER: Tim Lebo (TWC RPI)

Please join us this coming Wed (16 Apr) as TWC Ph.D. student Tim Lebo leads us in an interesting discussion of the challenges of adding provenance to deployed systems, using his current work extending OPeNDAP with PROV!

ABSTRACT: Adding provenance to existing systems can benefit users, but comes at an expense that may be difficult for some to justify. This trade-off can be overcome by increasing the value of provenance, by decreasing the cost to add it - or by doing both.

This talk discusses a contribution for each. First, we develop further the W3C PROV pingback technique so that it may reach its potential to interconnect provenance records that would traditionally sit in isolation, thus increasing their value. Second, we reduce the expense to publish the provenance of existing host systems by using minimal coupling to the Prizms Linked Data platform. Using an Earth Sciences scenario and the OPeNDAP data transport architecture as an example host system, we investigate how PROV pingback could work in practice, demonstrate its potential, and identify outstanding issues that must be addressed before it can be widely adopted.

BIOGRAPHY: Tim Lebo is a fifth year Ph.D. student on a campaign to capture, facilitate, and exploit the implicit connections throughout and among individual analytical processes, so that it is easier for analysts to create, understand, trust, and repurpose prior analytical results. The application of PROV Pingback joins a variety of other tools that Tim has been developing to form explicit links among data and their analyses, including Linked Data, PROV-O the PROV Ontology, DataFAQs data quality evaluation framework, and Content-Preserving Graphics.

TWeD Talk: HTTPA: HTTP with Accountability
Description:

TWed Talk: Weds, 02 Apr (7p, Winslow 1140)
TITLE: "HTTPA: HTTP with Accountability"
LEADER: Oshani Seneviratne (MIT CSHALS)

Please join us this Wed (02 Apr) as MIT CSAIL Ph.D. student Oshani Seneviratne leads us in a discussion of some of her current work investigating protocols for accountability on the Web!

ABSTRACT:
We have developed HTTPA, an architecture for the Web to address complex issues arising from data reuse. These issues include privacy violations and intellectual property rights violations. This talk will present the motivation for HTTPA based on results from a policy awareness study and some initial tools such as the License Usage Validator, and the Semantic Clipboard. These tools are limited to a particular type of content reuse, i.e. image reuse. Therefore, we extended our work to include policy awareness on any resource on the Web using HTTPA. HTTPA is built on open Web standards and uses the 'Provenance Tracking Network' (PTN), an open global trusted network of peer servers that logs resource usage data. Websites that conform to the architecture communicate information about transactions for any sensitive data items with the PTN. These logs can later be queried to check compliance with individual, organizational, state or federal policy and usage restrictions that assert no unauthorized data transfer or usage has taken place. We have evaluated this architecture using an electronic healthcare records application called Transparent Health that gives patients a better sense of how their sensitive data has been used.

BIOGRAPHY:
Oshani is a PhD candidate at MIT CSAIL. Her research is on social systems on the Web augmented with provenance, policy expressions and linked data. She is also working on using MIT app inventor to make disaster relief apps using SPARQL streams. She has previously worked on the Tabulator, a linked data browser, where she has introduced the 'pane' mechanism that can be used to introduce new visualizations to Tabulator very easily.

TWed Talk: Weds, 19 Mar (7p, Winslow 1140)
TITLE: "Context Modelling as a Service"
LEADER: Yu "Momo" Chen

Please join us TOMORROW (19 Mar) as Tetherless Ph.D. student Yu "Momo" Chen leads us in a discussion of some of his current work investigating context modeling as a service.

ABSTRACT: In this talk Yu Chen will discuss some of his current research on context modeling as a service. As more and more portable devices, e.g. mobile phones, are equipped with sensors, there is a huge potential in understanding what can be revealed from patterns in the sensor data, as it is expected to be highly correlated to human activities and behaviors. However, this sensor data is not easy or intuitive to analyze, especially as the noisy time series data requires both intensive heuristics and mathematical analysis to reflect the real significance of the raw data. Based on his research, Yu argues that a web service that can be delegated by any application that interacts with sensors will be of great interest. In this talk, Yu will discuss work he has done that helps move this idea forward.

BIOGRAPHY: Yu Chen is a fourth-year PhD student in Computer Science. His interests includes mobile sensor data analysis and context modeling using a combination of techniques such as machine learning, signal processing, language modeling etc.

TWeD Talk: Experiences Curating Science Metadata and Recommendations for Publishing Metadata
Description:
"There's always something happening Wednesday evenings in the Tetherless World!"

TWed Talk: Weds, 05 Mar (7p, Winslow 1140)
TITLE: "Experiences Curating Science Metadata and Recommendations for Publishing Metadata"
LEADER: Jesse Weaver

Please join us Wed, 05 Mar for the return of Tetherless Ph.D. recipient Jesse Weaver as he leads us in a discussion of some of his current work at the Pacific Northwest National Labs on RDESC, "Experiences Curating Science Metadata and Recommendations for Publishing Metadata"

ABSTRACT: "Experiences Curating Science Metadata and Recommendations for Publishing Metadata"

At present, much science metadata is utterly inaccessible (i.e., not shared), digitally inaccessible (i.e., not on the Web), or machine-incomprehensible (i.e., text). Although standard vocabularies like GCMD keywords and CF standard names are a step in the right direction, much more is needed in order to bridge the semantic gap between the detail of science metadata and the generality of posed questions. As part of the RDESC project, we attempt to demonstrably bridge this gap for a specific atmospheric science use case by incrementally developing an OWL ontology to accommodate the precision of various metadata, and by curating the metadata into semantically rich, RDF triples. The ontology and RDF data model enable us to meaningfully related heterogeneous metadata of varying precision from different sources. In this talk, I will primarily discuss the metadata curation effort that has taken place to date in RDESC and make recommendations for how to improve on publishing science metadata.

RDESC is a DOE/ASCR-funded project in collaboration with RPI that aims to facilitate discovery of science resources at the scale of the scientific community. The project involves the curation of existing science metadata, the development of recommendations for publishing science metadata, and the development of a prototypical web interface for discovering resources described by the curated metadata.

BIOGRAPHY: Jesse Weaver is a Research Computer Scientist in the Data Intensive Science Computing (DISC) group at Pacific Northwest National Laboratory (PNNL) in Richland, WA. He is the PI of the Streaming Hypothesis Reasoning (Shyre) project and the Resource Discovery for Extreme Scale Collaboration (RDESC) project, the latter of which is a DOE/ASCR-funded project in collaboration with RPI. Jesse is also a key member of the Center for Adaptive Supercomputing Software (CASS) where he contributes to the development of a distributed graph database called SGEM.

Prior to joining PNNL in April 2013, Jesse was a doctoral student at RPI where he wrote his dissertation entitled "Toward Webscale, Rule-based Inference on the Semantic Web via Data Parallelism" for which he co-received the 2013 Karen and Lester Gerhardt Prize. Jesse was the Dr. Shirley Ann Jackson and Dr. Morris A. Washington Patroon Fellow, the first recipient of a Patroon Fellowship. While at RPI, he participated in the champion team of the 2009 Billion Triples Challenge, co-organized the Workshop on High Performance Computing for the Semantic Web (HPCSW) in both 2011 and 2012, and interned as a software engineer at Facebook for the summer of 2011.

Prior to his graduate studies at RPI, Jesse was a software engineer at Raytheon IIS where he contributed to code parallelization and R&D in knowledge management/discovery. He received his B.S. in Computer Engineering from the University of Arkansas in Fayetteville in 2006.

Description:
The 17th biennial Ocean Sciences Meeting, co-sponsored by the Association for the Sciences of Limnology and Oceanography (ASLO), The Oceanography Society (TOS), and the American Geophysical Union (AGU), will be held at the Hawaii Convention Center in Honolulu from 23-28 February 2014. The Ocean Sciences Meeting (OSM) is an important venue for scientific exchange across broad marine science disciplines. Sessions will include all aspects of oceanography, especially multidisciplinary topics, as well as presentations that reflect new and emerging research on the global ocean and society, including science education, outreach and public policy. The OSM originated in 1982 as a joint effort between AGU and ASLO, TOS joined as a regular co-sponsor in 2004.

Increasing evidence of multiple human impacts on the oceans makes this is a critical time for the largest international assembly of ocean scientists, engineers, students, educators, policy makers, and other stake holders to gather and share their results on research, application of research, and education. What better place to hold the meeting than an island in the middle of the Pacific Ocean, where there is emphasis on mauka to makai (ridge to reef) connection, the ultimate in ecosystem-based management; where there is interest in combining traditional knowledge with science-based understanding; where islands are in threat of disappearing from sea level rise; and where East and West can easily meet? Throughout their history, Hawaiians have demonstrated a thorough understanding of sustainability with an approach to land and water use that allowed them to self-sustain nearly one million islanders. Today they build on that heritage with innovations in science and clean energy. Hawaii is a place where interdependence and sustainability are both historic and necessary.

"There's always something happening Wednesday evenings in the Tetherless World!"

TWed Talk: Weds, 12 Feb (7p, Winslow 1140) TITLE: Coding Provenance in Software and Matching Tools to Data LEADER: Patrick West

Please join us this week as the Tetherless World's Patrick West leads us in a discussion of his work with OPeNDAP [1] and ESIP's ToolMatch Project [2]

ABSTRACT: OPeNDAP.org has been providing software solutions for the access, manipulation, transformation, and dissemination of science data for over a decade now. But it's been only recently that we have started thinking about providing information about exactly how and from what that final data product was generated. The OPeNDAP provenance project looks to research the coding of software systems to provide provenance information and implement that in OPeNDAP.

And given those original datasets and that generated data product, what client software can be used to visualize that data and in what ways. The ToolMatch project looks to formalize the expression of the datasets, and client tools that can visualize them in some way, developing an ontology and set of inference rules that can help the user realize the full potential of their data search and access.

BIO: Patrick West is a senior software engineer with the Tetherless World Constellation at Rensselaer Polytechnic Institute.

TWeD Talk: Who are the Influencers? New Algorithms for Detecting Key Players in Social Networks
Description:
"There's always something happening Wednesday evenings in the Tetherless World!"

TWed Talk: Weds, 29 Jan (7p, Winslow 1140)
TITLE: Who are the Influencers? New Algorithms for Detecting Key Players in Social Networks
LEADER: Xiaohui Lu

Please join us this week as new TWC postdoc Xiaohui Lu leads us in what promises to be an interesting discussion of his work developing novel social network analysis algorithms.

ABSTRACT: One of the primary tasks of social network analysis is the identification of the influential actors in a social network. Centrality measures based on one's structural position, such as betweenness, closeness and degree centrality, are widely applied to various social networks for this purpose. However, these measures often suffer from prohibitive computational cost, non-intuitive assumptions, and limited applications. Meanwhile, with the explosive emergence and the widespread accessibility of online social network sites, large scale networks with multiple types of entities, such as author-publication, actor-movie, employee-email networks, are ubiquitous and readily available. However, due to size and multiple modes, classical centrality measures are helpless in such cases.

In this talk, I first present algorithms for pure social networks (actor-actor networks), then an algorithm for multi-mode networks. In pure social networks, centrality algorithms are good candidates. However, these centrality measures suffer from several issues - they either look solely at the structure of the network disregarding issues like attention nodes have to give to others or make a shortest path interaction assumption that might be impractical in large networks. Algorithms for pure social networks are not able to take advantage of abundant information hidden in multi-mode (heterogeneous) networks. I developed an algorithm to analyze such heterogeneous networks. The algorithm iterates from one type of objects to another, and importance of objects flow through these different types of edges. This algorithm is based on empirical observations - influential actors are likely to collaborate with influential others; good collaboration product tends to be in good groups.

BIO: Xiaohui Lu is a postdoctoral research associate at The Tetherless World Constellation at Rensselaer Polytechnic Institute. He earned a doctoral degree in computer science from Rensselaer Polytechnic Institute. His primary research interest is designing effective algorithms for key players identification in large-scale networks. He is also interested in information diffusion in complex networks, and he has broad interests across computational social science, data mining/machine learning.

Xinformatics Class Spring 2014
Description:
In the last 2-3 years, Informatics has attained greater visibility across a broad range of disciplines, especially in light of great successes in bio- and biomedical-informatics and significant challenges in the explosion of data and information resources. Xinformatics is intended to provide both the common informatics knowledge as well as how it is implemented in specific disciplines, e.g. X=astro, geo, chem, etc. Informatics' theoretical basis arises from information science, cognitive science, social science, library science as well as computer science. As such, it aggregates these studies and adds both the practice of information processing, and the engineering of information systems. This course will introduce informatics, each of its components and ground the material that students will learn in discipline areas by coursework and project assignments.
  • To instruct future information architects how to sustainably generate information models, designs and architectures
  • To instruct future technologists how to understand and support essential data and information needs of a wide variety of producers and consumers
  • For both to know tools, and requirements to properly handle data and information
  • Will learn and be evaluated on the underpinnings of informatics, including theoretical methods, technologies and best practices.

Advanced Web Science (Spring 2014)
Description:
Web Science is an inherently interdisciplinary area which explores how we can understand the workings and effect of the World Wide Web. In this project-oriented course, students will work both alone and in teams to design potential "killer apps" for the Web and/or mobile web infrastructure. Students will do a combination of ideation, study, design, experimentation, and implementation - as fits their skill set and major. Students coming out of the course will better understand what makes particular Web-based applications work, how to explore scaling of projects to the Web, and how to know what might or might not "go viral" in the modern information space.
This course attempts to provide the foundations of that understanding, exploring the fundamentals of the World Wide Web's function including the HTTP protocol, key algorithms that make the Web function, future trends, and social issues with respect to Web use and effect.

Data Analytics 2014
Description:
  • Introduce students to relevant methods to recognize and apply quantitative algorithms, techniques and interpretation
  • To develop students' strategic thinking skills, combined with a solid technical foundation in data and model-driven decision-making.
  • Develop ability to apply critical and analytical methods to formulate and solve science, engineering, medical, and business problems
  • In groups, students will identify qualitative problems and apply content analytics
  • Students will examine real-world examples using modern cyberinfrastructure to place statistical and data-mining techniques in context, to develop data-analytic thinking, and to illustrate that proper application is as much an art as it is a science.
  • By the end of the course, students can effectively communicate analytic findings to non-specialists
Data and Information analytics extends analysis (descriptive and predictive models to obtain knowledge from data) by using insight from analyses to recommend action or to guide and communicate decision-making. Thus, analytics is not so much concerned with individual analyses or analysis steps, but with an entire methodology. The world at-large is confronted with increasingly larger and complex sets of structured/unstructured information; from sensors, instruments, and generated by computer simulations; data is "hidden" in websites, application servers, social networks and on mobile devices. As a nation, assimilating information across disparate domains (e.g., intelligence, economics, science) has the potential to provide improved capabilities for decision makers. In commerce and industry, analytics-driven enterprises are becoming mainstream. Yet, there is a shortfall in the key education skills needed to meet the growing needs. Traditional enterprises are moving toward analytics-driven approaches for core business functions. In the government and corporations, cybersecurity problems are prevalent. The investment in advanced analytics capabilities could potentially be more broadly leveraged today and greater than any prior government investments in computing. Emphasis is now placed on disruptive data and information sources on the Web and Internet: using Web Science and informatics to explore social networks, platform competition, the "long tail" and economic or resource impacts of the search for new findings. Key topics include: advanced statistical computing theory, multivariate analysis, and application of computer science courses such as data mining and machine learning and change detection by uncovering unexpected patterns in data.

TWed Talk: Weds, 20 Nov (7p, Winslow 1140)
TITLE: "Text Analysis of Large Metadata Catalogs"
LEADER: Amar Viswanathan (TWC RPI)

Please join us as TWC Ph.D. student Amar Viswanathan leads us through a discussion and demo of tools and methods used for analyzing large dataset catalogs!

ABSTRACT: We will demonstrate the application of traditional IR methods including entity extraction[1], tf-idf[2] and (if time permits) topic modelling[3] on large collections of metadata such as the International Open Government Dataset Catalog (IOGDS[4]) --- over 1M datasets --- and the visualization of these results.[5] The focus of this talk will be on demonstrating how to use certain simple tools to generate results and produce quick visualizations, including word clouds and graphs. We will also discuss how the kinds of analysis performed on IOGDS including languages, categories, and keywords maybe used as source data for a question answering system like IBM's Watson.

BIO: Amar Viswanathan is a third year Computer Science PhD student working with Prof. Hendler since Fall 2011. Prior to joining RPI he worked as a Senior Software Engineer at Infosys Labs, Bangalore, India, where his primary work was on entity and event extraction, sentiment analysis leading into suggestion mining and extraction. Since the Summer of 2013 he has worked on IOGDS analytics and Watson@RPI and hopes to extend its capabilities to understanding Linked Data.

TWeD Talk: A First Look at the Deep Carbon Observatory Data Portal
Description:
"There's always something happening Wednesday evenings in the Tetherless World!"

TWed Talk: Weds, 23 Oct (7p, Winslow 1140) TITLE: A First Look at the Deep Carbon Observatory Data Portal
LEADER: John Erickson and members of the DCO Data Science Team (TWC RPI)

Please join us as members of the DCO Data Science Team demonstrate and discuss the DCO Data Portal!

ABSTRACT: In support of the Deep Carbon Observastory[0] the DCO-Data Science Team has adapted, extended, and integrated several open source applications and frameworks to create a novel Web-based collaborative research plaform well-suited to emerging science networks. In this talk the DCO-DS team will discuss how we have combined platforms including Drupal[1], VIVO[2], CKAN[3], and the Handle System[4] in ways that leverage and reinforce knowledge networks inherent to the distributed research enterprise.

The DCO Data Portal is a Web-based service integrating an object-type repository, collaboration tools, an ability to identify and manage all key entities in the platform, and an integrated portal to manage diverse content and applications, with varied access levels and privacy options. In this informal talk we'll demonstrate how global science networks composed of people, diverse intellectual artifacts produced or consumed in research, organizational and/or outreach activities, as well as the relations among them can be modeled as knowledge networks, documented using formal ontologies and instantiated within platforms including the DCO Data Portal. Nodes within such networks may be people, organizations, datasets, events, presentations, publications, videos, meetings, reports, groups, and more. In such a heterogeneous ecosystem, common informatics approaches are used to co-design and co-evolve the needed research platforms to help ensure they reflect what real people want to use them for.[5]

ICSTI 2013 Workshop - Data and Non-Data Integration
Description:
The International Council for Scientific and Technical Information (ICSTI) will hold a half-day workshop for the morning of Wednesday, October 16, 2013, as part of the 2nd Annual CASRAI International Conference. The workshop theme is “Data and Non-Data Integration – A Journey Across Disciplines.”

Thanks to the creativity and innovation of scientists, libraries, publishers, and information and technology communities, scientific discovery is being accelerated through the seamless integration and synthesis of digital data and non-data (e.g., text, multimedia, visualization). Rapidly making sense of huge volumes of data and facilitating easy navigation between data and non-data are enablers of new knowledge – and discovery. In this workshop, we will explore how this integration is taking place across a broad range of disciplines, such as environmental sciences, life sciences, chemistry, engineering, geosciences, and crystallography.

TWeD Talk: MealQA: A food-oriented intelligent assistant
Description:
"There's always something happening Wednesday evenings in the Tetherless World!"

TWed Talk: Weds, 25 Sep (7p, Winslow 1140)
TITLE: MealQA: A food-oriented intelligent assistant (Summer Internship Talk)
LEADER: Yanning (Yu) Chen

Please join us this week as Yu Chen leads us in a discussion of his summer internship work with the Samsung R&D Center!

ABSTRACT: During the summer internship at Samsung R&D Center, TWC grad student Yu Chen worked on the MealQA system, a food-oriented intelligent assistant which can answer natural language queries w.r.t. food and dishes. For example, given a natural language query such as "What's the best restaurant for bibimbap?" the system is able to provide a list of Korean restaurants that offer bibimbap [1] (based on menus and other data), ranked according to sentiment analysis and entity extraction from available reviews. Yu's responsibility was to develop a ranking engine that provides the "most consistent" results at the front in the ranking list. The techniques include Bayesian networks and information theory. The dataset Yu trained the model on is based on Freebase, DBpedia and some proprietary datasets.

BIO: Yu Chen is a fourth-year PhD student (second year officially in the CS Department). His research interests include time series sensor data analysis. He's been working with Prof. Peter Fox on the Deep Carbon Observatory project.

Research Data Alliance Second Plenary
Description:
The Research Data Alliance (RDA) Second Plenary Meeting is sponsored by RDA/US through grants from the United States of America National Science Foundation (NSF) and the National Institute of Standards and Technology (NIST).

Data sharing offers important benefits for scientific progress and advancement of knowledge. However, several limitations and barriers in the general adoption of data sharing are still in place. Probably the most important challenge is that data sharing is not yet very common among scholars and is not yet seen as a regular activity among scientists, although important efforts are being invested in promoting data sharing.

The focus of this second plenary is Building Global Partnerships.

TWeD Talk: Introduction to Collustra Visual SPARQL Editor
Description:
"There's always something happening Wednesday evenings in the Tetherless World!"

TWed Talk: Weds, 11 Sept (7p Winslow 1140)
TITLE: Introduction to Collustra Visual SPARQL Editor (with Group Discussion)
LEADER: Evan Patton

ABSTRACT: Last semester TWC Ph.D student Evan Patton presented semantic web support for the MIT AppInventor platform that enables Android developers to use linked data to power applications[1]. However, application of this work revolves around proficient understanding and ability to construct SPARQL queries, which is a challenge for the target audience of the AppInventor. This summer Evan began work with graduate students at MIT's Decentralized Information Group (DIG) to develop a query-by-example inspired HTML5 application, Collustra[2], for constructing bottom-up SPARQL queries given a SPARQL endpoint. Evan and the MIT team make use of the SPARQL Inference Notation (SPIN) [3] to represent SPARQL queries in RDF so that queries can be stored in an endpoint with the goal of being able to index and search them. This also enables queries to be accessed from within AppInventor to ease linked data app development.

On Wednesday Evan will demonstrate an alpha version of the software and provide a road map in the first portion of the talk. For the remainder of the time there will be a group discussion on how tools such as Collustra could be used within Tetherless World and elsewhere to encourage access to linked data and what improvements are necessary to foster this growth. Students who are new to the lab or interested in learning SPARQL will benefit most from this talk. If anyone is interested in working on this project, Evan will be available after the talk or you may contact him via email.

Description:
To instruct future scientists how to sustainably generate/ collect and use data for their research as well as for others: data science. To instruct future technologists how to understand and support essential data and information needs of a wide variety of producers and consumers For both to know tools, and requirements to properly handle data and information Will learn and be evaluated on the full life-cycle of data and relevant methods, technologies and best practices.
Science has fully entered a new mode of operation. Data science is advancing inductive conduct of science driven by the greater volumes, complexity and heterogeneity of data being made available over the Internet. Data science combines of aspects of data management, library science, computer science, and physical science using supporting cyberinfrastructure and information technology. As such it is changing the way all of these disciplines do both their individual and collaborative work. Data science is helping scienists face new global problems of a magnitude, complexity and interdisciplinary nature whose progress is presently limited by lack of available tools and a fully trained and agile workforce. At present, there is a lack formal training in the key cognitive and skill areas that would enable graduates to become key participants in escience collaborations. The need is to teach key methodologies in application areas based on real research experience and build a skill-set. At the heart of this new way of doing science, especially experimental and observational science but also increasingly computational science, is the generation of data.
