http://www.w3.org/2005/Incubator/urw3/#Minutes
- Minutes approved without discussion.
- Review status of action items from previous meeting
Action
1:Giorgos, please look more into wiki to HTML tool and make
recommendation on use.
Action 1 is still open.
Paulo suggests that editing team should manually translate to html.
Peter agrees.
Action
2: Editing Team continue from last meeting Actions 2, 4, and 5: insert
more detailed specifics in discussion section of discovery use case; work on
appropriately connecting Discovery use case to uncertainty ontology; start
identifying "methodologies" for addressing the issue of annotating the use
cases.
Kathy suggests that
Action 2 should be deferred to report from editing team.
Action 3: Kathy wants to comment on [fuzzy vice probabalistic]
link and extend.
Kathy made some suggested changes to Peter and Mitch's suggestions on
combining probability and fuzzy.
http://www.w3.org/2005/Incubator/urw3/wiki/OpenIssues
Peter suggested that both suggestions are appropriate.
Kathy asks Peter to find a citation for fuzzy preference functions.
Peter found citation: Optimal aggregation algorithms for middleware, with
Amnon Lotem and Moni Naor. J. Computer and System Sciences 66 (2003), pp.
614-656. Extended abstract appeared in Proc. 2001 ACM Symposium on
Principles of Database Systems (PODS '01), pp. 102-113.
http://www.almaden.ibm.com/cs/people/fagin/
ACTION: Kathy and Peter to add citations to the
reference list and link them from the fuzzy/probabilistic scenario.
Action 4: Combined to action 2.
Action 5: Vipul to expand one of the HCLS use
cases with types of uncertainty exhibited (using uncertainty ontology as
guide)
ACTION: (carry over from last meeting) Vipul to
expand one of the HCLS use cases with types of uncertainty exhibited (using
uncertainty ontology as guide).
Mitch suggested that the fuzzy-probabilistic scenario be made a bit more
explicit, i.e., it be supported by graphical represenations of fuzzy
functions and giving an explicit example of the fuzzy preference function
for this particular scenario.
Action 6: Peter to work on the extraction use
case.
Kathy summarized that Peter did a draft relating extraction use case to
uncertainty ontology and there was a discussion over the email list.
Claudia thinks that we need to discuss the annotation process.
ACTION: Peter to continue working on extraction use
case.
Kathy noted that we have an agenda item to discuss uncertainty ontology.
ACTION: Kathy to work with Mitch and Peter to extend
and expand f/p scenario and add graphical representation of fuzzy
preferences.
Action 7: Ken to start email on interest and
availability for January/February timeframe for full ftf, including possible
locations.
ACTION: (carry over from last meeting) Ken to start
email on interest and availability for January/February timeframe for full
ftf, including possible locations
- Report on Busan F2F
- ACTION: Authors annotate use cases with
uncertainty ontology.
- Kathy said that Discovery use case has been annotated.
http://www.w3.org/2005/Incubator/urw3/wiki/Discovery
- Peter isn't sure how far we need to go on annotating use cases, he
suggests a more detailed annotation which shows that the ontology can
help in finding data.
- Kathy said that this upper level ontology is
not sufficient, but shows necessity for future work on uncertainty
interchange format.
- Claudia thinks that we need also to define in a
more precise way what we can do with such annotations.
- Kathy asks:
For instance, how do these annotations help a software tool to work with
the use case? Mitch, can you comment on this?
- Peter notes: GRDDL.
- Thomas asked whether Peter thinks annotation should be in RDF.
- Peter
is not so worried about the syntax. He is concerned about the semantic
content.
- Kathy thinks that it should support automated sharing of
data.
- Mitch agrees that ontology is not detailed enough for some
purposes. His intent is that it is a top level structure.
- Kathy said
that Mitch developed the ontology to help us evaluate whether we were
covering all the essential aspects of uncertainty. If we annotate use
cases, we can uncover holes in our use cases. We can find kinds of
uncertainty for which we don't have a use case, and develop a use case
to fill that gap.
- Kathy asks whether we need to fully work out the
ontology to meet our charge?
- Mitch thinks we do not have time to
fully work out an ontology.
- Claudia and Peter think we need to go
lower, identify where in the ontology the interchange format fits.
- Mitch thinks we can do this with the speaker scenario
-
ACTION: Mitch, Peter and Kathy to develop a
speaker use case and link to ontology.
- Peter suggests to extend TBox and some Abox. He asks for URL.
-
ACTION: Trevor and Thomas to make use cases from
their URSW papers.
- Kathy suggested that Thomas will send the people who want to join URW3
contact info for Ken and Kathy.
- Paolo needs to leave.
- Another topic debated at Busan F2F was uncertainty reasoning visibility at
major conferences.
- Peter recomends The Web of Uncertainty - Computational Intelligence and
the Internet, session is announced at
http://www.informatics.manchester.ac.uk/~zeng/FS2008/FS18.htmy
FUZZ-IEEE Hong Kong 2008.
- Kathy noted that Preliminary call on ISWC came out 9 November,
http://iswc2008.semanticweb.org/wp-content/uploads/2007/11/prelim_cfp_iswc2008.pdf
- Claudia said that about our visibility also icsc could be an interesting
place.
- Peter asks Claudia for more detaisl on icsc.
- Claudia said
http://icsc2007.eecs.uci.edu/index.html this is the url. This year
they have had the first edition and they are interested in continuing
with new topics and also places for the next conference edition.
- Kathy noted that Mitch volunteered to ask Amit Sheth, one of the program
chairs, to put some uncertainty people on the PC and add some
uncertainty topics.
- Claudia will ask Steffen the same.
- Peter suggests a topic relating to automating uncertainty processing.
- Mitch thinks the difference comes with incorporating uncertainty into
reasoning.
- Petter suggested to add reasoning and querying.
- Peter says inference engines are not so good at querying. Cannot load 1
billion triples into Protege. Querying becomes an important issue,
especially in presence of uncertainty.
- ACTION: Mitch and Claudia talk to
ISWC08 PC chairs about uncertainty PC members and topics.
- Another topic debated at Busan F2F was
discussion of whether new people can join now or should we ask them to
wait.
- Most people seem to think people should be able to join now.
- Discussion of uncertainty ontology and annotation of use cases
Kathy noted
that we already discussed this under a previous agendum.
- Report from editing committee -- way forward on report
.
- Kathy notes that we don't have a report, but we have a wiki draft.
We have wiki pages for each use case. In the draft report, we have a
place to summarize each use case.
- Paulo suggests that each use case writer should summarize the use
case for the report.
http://www.w3.org/2005/Incubator/urw3/wiki/DraftFinalReport .
Otehrwise, he has nothing new beyond his email.
http://lists.w3.org/Archives/Public/public-xg-urw3/2007Nov/0001.html
- Kathy thanks to Paulo for all his work on the draft report.
- ACTION: use case authors write
summaries of their use cases.
- Paulo recommends we subscribe to the report page so we are notified
when it changes.
- ACTION: use case authors should insert their
use cases into draft final report
- Other business
- ACTION: Matthias to report on Springer
volume at next meeting.
- Meeting was adjourned.
