Homework
1. Update the page Extensions to Water Quality Portal http://tw.rpi.edu/web/comment/reply/2193
to add your Citizen Science Section (what you wrote in class is on the titanpad http://twc.titanpad.com/267?
2. Add your name to one of two groups: (Linyun had received approval from Deborah to be in both groups).
Group 1: Aims to provide what a "Natural Resource Manager" needs to help them do their job. The natural resource manager needs
information from authoritative sources (datasets from USGS or related environmental monitoring sources) and through your project, encode
additional information (e.g. different names used in the different data sets, provenance information, etc.) that enable the natural resource
manager to make more informed decisions. Natural resource management professionals create, plan, monitor, direct and evaluate programs
that preserve the environment (source: http://bit.ly/yBs9Dq)
Ping propose an extension of SemantEco that's around the topic of animal feed operations at http://tw.rpi.edu/web/node/2193#comment-51, you can take a look if interested.
* This group might work more closely with USGS.
* Possible Data Source (PDF; not ideal, but a possible starting point):

Note: Both groups will work on the same platform, providing exentions in two different aspects.
3. By Sunday evening, March 4 you must have your name on one of the two lists, and have met with your classmates to vote on which extension your group will implement. You must post this decision by Monday noon, March 5.
4. Be prepared to present in class the answers to the following questions. Post the time of your presentation on the course website for the March 5, class.
*1 - One question the resource manager or citizen scientist seeks to answer through your group's extension *2 - One example of a successful answer to the question that would be hard to do without your group's extension *3 - One or two data sources that provide the data the resource manager or citizen scientist will access through your extension in order to answer the question in number 1. *4 - A starting point for initial tasks - what you will do first to implement the above. *5 - Name two papers or projects done by others that the data manager or citizen scientst group should know about (that they have found by doing literature / web searches)
Notes:
1. If you have not identified which group you will be in by posting to this page http://tw.rpi.edu/web/node/2193 by Saturday, with the group that you want to be in, then Deborah will assign you to either group 1 or group 2.

Notes - Apr-24 Titan Pad
Group presentations: Each member of the group will present one claim for either the advantage of semantics or provenance AND show an example in your application where you are showing value.
Note that these write ups need to be included in the project web page.
Please send your presentations to abigail and deborah.
the presentation should include
1 - the claim . e.g., encoding information in OWL allows us to do better semantic integration. Specifically encoding the meaning of polluted thing with the OWL definition that shows a thing that has a contaminant reading that is out of range allows us to automatically classify polluted things.
2 - the background semantic encoding or provenance encoding
3 - what would have been hard to do without using semantics or provenance encodings
4 - an example of the provenance usage or the owl definition in the setting of your example.
Show the OWL definition of a term if you are making claims about semantics.
Show the provenance encoding if you are making claims about provenance.
Show the result of the reasoner result for one query that proves your point
Show how you are exposing provenance in your interface if you are making claims about provenance
Since the groups did not go over the presentation web site last week, we will also need to do that this week.

Final project draft presentation. There will be an iteration on this presentation aimed at what it takes to make this publishable.
Draft presentation:
Each group has an hour to present total.
The presentation should include speaking slots for everyone on the team.
The project presentation needs to include:
1. Project overview
2. Use case
3. Architecture and technical approach making sure to include
a. Overview of the ontology
b. Provenance approach
4. Demonstration of the system in action. Make sure to include
a. Example using the ontology to answer a question in your use case
b. Example where you are using provenance to create some kind of provenance-aware service
c. a link to your outward facing project web site that also includes screen shots of your system in action as well as a link to the live demonstratoin
5. Related work
6. Discussion including
a. Learnings from the project
b. Claims about the need for and value of semantic technology in your project
c. Claims about the need for and value of provenance in your project
7. Future work
8. Roles and responsibilities for each of the team members
In the draft presentation if something is not completed for this week, let us know what will be done for next week.
The final project will include a final presentation and a walk through of your team outward facing web site. That web site needs to be on a Tetherless world machine (not just a student laptop) and is expected to stay up after the class ends.
The final web site needs to include both a static demonstration including screen grabs of your system in action as well as a link to the live system. We understand that the live system may not work after the class finishes (although we hope it continues to function) but the static demonstration should be available into the future.

Final assignment:
Final Assignment Advanced Semantic Technologies 2012
This assignment has two sections:
Section 1 is to completed as a team and is due on the last day of class – May 8 not later than 1pm.
Section 2 is completed individually and emailed to both Abigail and Deborah individually. This is due on May 10 at 10 am.
Section 1 – to be completed as a team.
1 – Finalize your outward facing project web site. The web site must be on a Tetherless world machine.
Your web site must have at least the following sections:
• Overview
• Technical Foundations . This section must include a description of the architecture and technical approach. It should include a subsection describing the ontology overview and the provenance approach.
• Use Case
• Demonstration - with static web page shots showing the results of asking a question and the results of your system.
• Discussion
o Learnings from your project
o Make sure to include claims you are making about your project showing
The need for and value of semantics in your demonstration.
The need for and value of provenance in your demonstration
o Make sure to support your claims with real examples showing what was difficult without your ontology definitions and the reasoner and/or without the provenance encoding and the provenance-aware services.
• Related Work - making sure to describe how your work leverages the related work and/or is different from it.
• Data sources used
• Future Work
• Bibliography (this can and most likely should include web sites)
Please also include an appendix that includes a description of the team members and what each team member contributed to the project.
You need to email a copy of the web page and your presentation to Abigail and Deborah by 12:59 pm on May 8.
Section 2.
This portion of the assignment must be done individually. This is to be submitted by email to Abigail and Deborah and is due no later than May 10 at 10 am eastern time.
A: Evaluation of you and your team members. In this section you are asked to evaluate your individual performance on the team and also of your team members. You only need to fill this in for yourself and team members. Please do make sure to fill it in on yourself.
For each person on your team starting with yourself and for each category below, please give a numerical rating from 1-10 with 10 being the best and then include one to four sentences on the reasoning for the rating.
Also, if someone other than a team member was particularly helpful to your project, please include comments about their contributions. You will be graded on your evaluation of yourself as well as your evaluation of you team members.
You do not need to do any evaluation of people NOT on your team but you must evaluate each member of your team separately including yourself.
Make sure to evaluate each team member in all categories.
The categories are:
1. Responsibilities: respond with a numerical value 1-10 with 10 being the highest AND include a short text description of responsibilities.
2. Challenges with working with this person: Respond with a number - 10 means no challenges, 1 means very many challenges. Describe challenges in text. You do not need to include challenges for yourself.
3. Accomplishments in the project: Include a numerical value between 1-10 with 10 being the highest. Include a textual description. (Note - it could be that someone accomplished something that was not part of their responsibilities which is why this is separate from point 1 above).
4. Work Effectiveness: numerical evaluation. 10 means very effective; 1 means very ineffective. Include a textual description.
5. Team Meeting Attendance: numerical evaluation. 10 means attended all meetings; 1 means missed many meetings. Include a textual description.
6. Communication skills: numerical evaluation. 10 means excellent communication. Include a textual description.
7. Teamwork: numerical evaluation. 10 means excellent teamwork. 1 means poor teamwork. Include a textual description.
8. Improvement Options: A description of each team member (including yourself ) could have improved individual performance as well as team performance.
9. Optional – comments
(renumbered after noticing that accomplishment did not have a number next to it)
B. Provide at least two clear statements of something that you learned in the class that would allow you to design or implement or write about a semantic technology project in the future. Give one example for each learning.
C. Leverage something that you learned in the class and/or did for the project to demonstrate the value of semantic technologies in your application. This could be considered input to the claims section in a paper you would submit for publication. Each claim should be able to fit into one sentence. You can support it with an example but make sure the claim can be articulated succinctly. This work should be done individually. When you defend the claim make a connection make a statement about something that you did on the project that enabled the team to make this claim. So for example you and other members of your team may make similar claims but each individual would have a different description of how their work supports this claim.
D. Leverage something that you learned in the class and/or did for the project to demonstrate the value of provenance in your application. This could be considered input to the claims section in a paper you would submit for publication. Each claim should be able to fit into one sentence. You should support it with an example but make sure the claim can be articulated succinctly. This work should be done individually. When you defend the claim make a connection make a statement about something that you did on the project that enabled the team to make this claim.
Note – if you have already been discussing your claims with team members as the result of previous work on the project, please include a statement about who you did what with.

Course evaluation worksheet
Academic Integrity
Student-teacher relationships are built on trust. For example, students must trust that teachers have made appropriate decisions about the structure and content of the courses they teach, and teachers must trust that the assignments that students turn in are their own. Acts, which violate this trust, undermine the educational process. The Rensselaer Handbook of Student Rights and Responsibilities defines various forms of Academic Dishonesty and you should make yourself familiar with these. In this class, all assignments that are turned in for a grade must represent the student’s own work. In cases where help was received, or teamwork was allowed, a notation on the assignment should indicate your collaboration. Submission of any assignment that is in violation of this policy will result in a penalty. If found in violation of the academic dishonesty policy, students may be subject to two types of penalties. The instructor administers an academic (grade) penalty, and the student may also enter the Institute judicial process and be subject to such additional sanctions as: warning, probation, suspension, expulsion, and alternative actions as defined in the current Handbook of Student Rights and Responsibilities. of an academic grade penalty or . If you have any question concerning this policy before submitting an assignment, please ask for clarification.
Attendance Policy
Enrolled students may miss at most one class without permission of instructor.
Once one class has been missed (with or without permission) no additional classes may be missed without permission.
Grading Policy
Grades will be determined based on homework assignments along with class participation. Late assignments will drop 10% of the possible value of the assignment for each day late.
Course: Advanced Semantic Web
