Data and Semantics — Topics of Interest at ESIP 2015 Summer Meeting

July 27th, 2015

The ESIP 2015 Summer Meeting was held at Pacific Grove, CA in the week of July 14-17. Pacific Grove is such a beautiful place with the coast line, sand beach and sun set. What excited me more are the science and technical topics covered in the meeting sessions, as well as the opportunity to catch up with friends in the ESIP community. Excellent topics + a scenic place + friends = a wonderful meeting. Thanks a lot to the meeting organizers!

The theme of this summer meeting is “The Federation of Earth Science Information Partners & Community Resilience: Coming Together.” Though my focus was Semantic Web and data stewardship relevant sessions, I was able to see the topic ‘resilience’ in various presented works. It was nice to see that the ESIP community has an ontology portal. It implements the Bio Portal infrastructure and focuses on collecting ontologies and vocabularies in the field of Earth sciences. With more submissions from the community in the future the portal has great potential for geo-semantics research, similar to what the Bio Portal does for bioinformatics. An important topic was reviewing progress and discussing directions for the future. Prof. Peter Fox from RPI offered a short overview. The ESIP Semantic Web cluster is nine years old, and it is nice to see that through the cluster has helped improve the visibility of semantic web methods and technologies in the grand field of geoinformatics. A key feature supporting the success of Semantic Web is that it is an open world and it evolves and updates.

There were several topics or projects of interest that I recorded during the meeting:

(1) It recently released version 2.0 and introduced a new mechanism for extension. There are now two types of extensions: reviewed/hosted extensions and external extensions. The former (e1) gets its own chunk of namespace: All items in that extension are created and maintained by their own creators. The latter means a third party to create extensions specific to an application. Extensions to location and time might be a topic for the Earth science community in the near future.

(2) GCIS Ontology: GCIS is such a nice project it is incorporated several state-of-the-art Semantic Web methods and technologies. The provenance representation in GCIS means it is not just a static knowledge representation. It is more about what are the facts, what do people believe and why. In the ontology engineering for GCIS we also see the collaboration between geoscientists and computer scientists. That is, conceptual model came first, as a product that geoscientists can understand, before it was bound to logic and ontology encoding grammar. The process can be seen as within the scope of semiology. We can do good jobs with syntax and semantics, and very often we will struggle with the pragmatics.

(3) PROV-ES: Provenance of scientific findings is receiving increasing attending. Earth science community has taken a lead on working of capturing provenance. The World Wide Web Consortium (W3C) PROV standard provide a platform for Earth science community to adopt and extend. The Provenance – Earth Science (PROV-ES) Working Group was initiated in 2013 and it primarily focused on extending the PROV standard, and tested the outputs with sample projects. In the PROV-ES hackathon at the summer meeting, Hook Hua and Gerald Manipon showed more technical details of with PROV-ES, especially about its encodings, discovery, and visualization.

(4) Entity linking: Jin Guang Zheng and I had a poster about our ESIP 2014 Test bed project. The topic is about linking entity mentions in documents and datasets to entities in the Web of Data. Entity recognition and linking is a valuable work in works with datasets collected from multiple sources. Detecting and linking entity mentions in datasets can be facilitated by using knowledge bases on the Web, such as ontologies and vocabularies. In this work we built a web-based entity linking and wikification service for datasets. Our current demo system uses DBPedia as the knowledge base, and we have been collecting geoscience ontologies and vocabularies. A potential future collaboration is to use the ESIP ontology portal as the knowledge base. Discussion with colleagues during the poster session shows that this work may also be beneficial to works on dark data, such as pattern recognition and knowledge discovery from legacy literature.

(5) Big Earth Data Initiative: This is an inter-agency coordination work for geo-data interoperability in US. I would copy paste a part of the original session description to show the detailed relationships about a few entities and organizations that were mentioned: ‘The US Group on Earth Observations (USGEO) Data Management Working Group (DMWG) is an inter-agency body established under the auspices of the White House National Science and Technology Council (NSTC). DMWG members have been drafting an “Earth Observations Common Framework” (EOCF) with recommended approaches for supporting and improving discoverability, accessibility, and usability for federally held earth observation data. The recommendations will guide work done under the Big Earth Data Initiative (BEDI), which provided funding to some agencies for improving those data attributes.’ It will be nice to see more outputs from this effort and compare the work with similar efforts in Europe such as the INSPIRE, as well as the global initiative GEOSS.

GYA, CODATA-ECDP and Open Science

June 7th, 2015

During May 25-29, 2015, the Global Young Academy (GYA) held the 5th International Conference for Young Scientists and its Annual General Meeting at Montebello, Quebec, Canada. I attended the public day of the conference on May 27, as a delegate of the CODATA Early Career Data Professionals Working Group (ECDP).

The GYA was founded in 2010 and its objective is to be the voice of young scientists around the world. Members are chosen for their demonstrated excellence in scientific achievement and commitment to service. Currently there are 200 members from 58 countries, representing all major world regions. Most
GYA members attended the conference at Montebello, together with about 40 guests from other institutions, including Prof. Gordon McBean, president of the International Council for Science and Prof. Howard Alper, former co-chair of IAP: the Global Network of Science Academies.

GYA issued a position statement on Open Science in 2012, which calls for scientific results and data to be made freely available for scientists around the world, and advocates ways forward that will transform scientific research into a truly global endeavor. Dr. Sabina Leonelli from the University of Exeter, UK is one of the lead authors of the position statement, and also a lead of the GYA Open Science Working Group. A major objective of my attendance to the GYA conference is to discuss the future opportunities on collaborations between CODATA-ECDP and GYA. Besides Sabina, I also met Dr. Abdullah Tariq, another lead of the GYA Open Science WG, and several other members of the GYA executive committee.
The discussion was successful. We mentioned the possibility of an interest group in Global Open Science within CODATA, to have a few members join both organizations, to propose sessions on the diversity of conditions under which open data work around the world, perhaps for the next CODATA/RDA meeting in Paris or later meetings of the type, to collaborate around business models for data centers, and to reach out to other organizations and working groups of open data and/or open science, etc.

GYA is such an active group both formed and organized by young people. And I was so happy to see that Open Science is one of the four core activities that GYA is currently promoting. I would recommend ECDP and CODATA members to see more details of GYA on the website and propose future collaborations to promote topics of common interest on open data and open science.

DCO-DS participation at Research Data Alliance Plenary 5 meeting

April 30th, 2015

In early March I attended the Research Data Alliance Fifth Plenary and “Adoption Day” event to present our plans for adopting DataTypes and Persistent Identifier Types in the DCO Data Portal. This was the first plenary following the publishing of the data type and persistent identifer type outputs and the RDA community was interested in seeing how early adopters were faring.

At the Adoption Day event I gave a short presentation on our plan for representing DataTypes in the DCO Data Portal knowledge base. Most of the other adopter presentations were limited to organizational requirements or high-level architecture around data types or persistent identifiers – our presentation stood out because we presented details on ‘how’ we intended to implement RDA outputs rather than just ‘why’. I think our attention on technical details was appreciated; from listening to the presentations it did not sound like many other groups were very far into their adoption process.

My main takeaways from the conference were the following:
– we are ahead of the curve on adopting the RDA data type and persistent identifier outputs
– we are viewed as leaders on how to implement data types; people are paying attention to what we are doing
– the chair of the DataType WG was very happy that we were thinking of how data types made sense within the context of our existing infrastructure rather than looking to the WGs reference implementation as the sole way to implement the output
– the DataType WG reference repository is more proof-of-concept then production system
– The data type community is interested in the topic of federating repositories but is not ready to do much on that yet

Overall I think we are well positioned to be a leader on data types. Our work to-date was very well received and many members involved in the DataType WG will be very interested in what more we have to show next September at the Sixth Plenary.

Good work team and let’s keep up the good work!

Another AGU and we all get wet from the rain in San Fran…

January 10th, 2015

The 2014 Meeting of the American Geophysical Union in the wet city of San Francisco has not yet faded from memory. Unfortunately, it may be remembered for the “year of the RFID mess” over the great science progress. However, let’s start with the positive. Rensselaer’s Tetherless World was well represented – see what we did at = Patrick, Stephan, Marshall, Evan and Paulo (representing others including Linyun and Han) in talks, posters covering both research and project progress, and the academic booth (go RPI!). This year, we presented in Informatics (IN) and Education (ED) sessions with talks and many posters. Just on a logistics note, I was very pleased to have the exhibit hall adjoined to one of the poster halls this year. This made the task of moving between them and not missing one or the other, much easier. Hope that continues. It was another excellent year for Informatics; I’ve misplaced the stats but suffice to say increasing numbers of abstracts, great student contributions and a sea of new faces. A continuing treat is the Leptoukh Lecture (honouring Greg L, whom I still miss very much). This year, Dr. Bryan Lawrence (working in the UK, but actually a Kiwi) gave a tour de force lecture on computation and data aspects of climate science. The attendance was excellent, clearly pulling in a wide cross-section of attendees from well beyond the IN folks. Thanks Bryan. This year was the change over for Informatics leadership with Kerstin Lehnert taking over from Michael Piasecki as President – thanks Michael for your leadership and efforts over the last two years. Ruth Duerr (NSIDC) came in as President-Elect and Anne Wilson (CU/LASP) as secretary. Diversity rules in Informatics!!!

In regard to IN poster sessions, we saw an increase in the flash mob approach. What is that you ask? It is where, at an appointed time during the poster session, the session convener arranges for all poster presenters to be present. After having also advertised by twitter, email and general coercion, they gather poster attendees around each poster (in order, down the row). The presenter has 5 minutes to present their poster and then the mob moves on. It has shown to be a very effective way of engaging attendees and the presenters. If the session organiser has pre-planned it, the sequencing can also be very effective. After each has been presented, may attendees stay to quiz specific posters they were interested in. The one aspect that makes this style hard is the general noise level in the poster hall. Poster presenters need to “speak up” and project their voice: not all are prepared for that but it is very good practice!

I am author / co-author on quite a few presentations each year. This year I had two posters (both invited) as lead. You can see them via the link above. Sixth generation of data and information architectures, and Anatomy and Physiology of Data Science drew quite a lot of interest. But I must say, I did enjoy getting to stand with Mark Parsons at our poster “Why Data Citation Misses the Point” (I will add that to the website) and elaborate on our premise. Interestingly, we had a lot of agreement with the work — we’d hope to provoke arguments (!! as usual !!). Now to find time to write that up.

I want to acknowledge the excellent presentation of other works I was co-author on. The TWCers noted above are indeed skilled and knowledgeable researchers and practitioners. I know that but it is always excellent to have peers approach me to tell me that and how impressed they are with both the work and the people!

And the RFID issue – just go here and see for yourselves:

See all of you next December.
