Scott Marshall PeterYim: now speaking - Mr. MatthewHorridge (U of Manchester) - "The OWL API: a Java API for working with OWL 2 ontologies" FrankChum: Are the versions backward compatible? Axel Polleres: What's the relation OWLAPI vs dig regarding the reasoning interface? PeterYim: (just for those who are unfamiliar with the process) we will hold Q&A until after all the presentations are done. We should have time for discussion then, hopefully. Feel free to capture your questions or remarks here, partly using this as a placeholder, and partly to document that for the records PeterYim: now speaking - Dr. TimRedmond & Dr. TaniaTudorache (Stanford-BMIR) - "The Protege Tool Suite for Editing OWL Ontologies" NicolasRouquette: It is often difficult to tell which ontology asserted a particular axiom and which axioms a particular ontology asserts. NicolasRouquette: The class browser view in particular shows all classes across all loaded ontologies -- although we can show the ontology-specific prefix to tell which ontology declares a particular class, it is sometimes difficult to get a sense of all the classes declared in a particular ontology. PeterYim: now speaking - Dr. AndreasHarth (The NeOn Project; Institute AIFB, Karlsruhe Institute of Technology) - "The NeOn Toolkit" PeterYim: now speaking - Dr. EvrenSirin (Clark & Parsia) - "Pellet: OWL 2 Reasoner" Axel Polleres: afraid I need to run, thanks for the interesting talks! PeterYim: thank you for your participation - the entire proceedings will be available on our archives - slides, audio recording, chat transcript, and all (just come back to the session page in a day or two) RaviSharma: @Evren - Pronto, does it break the distribution into histograms and for each histogram you get the same reasoned answer i.e. is it equivalent to making it deterministic within the histogram for a given axiom (or / Assertion)? RaviSharma: @Evren - how does Pronto discover inferences that are probabilistic does it apply the above process in previous question in reverse to fill a particular histogram with population / samples? EvrenSirin: Pronto uses lexicographic entailment algorithms to perform default probabilistic reasoning EvrenSirin: The semantics is based on first order probabilistic logic EvrenSirin: The computation of probabilistic inferences has several steps and involves solving linear equations among others Enrico Franconi: @Evren, which is the reference for the integrity constraint validator? Is it just what we can find on the web page? EvrenSirin: @Enrico, longer technical report has several corrections: http://www.cs.rpi.edu/%7Etaoj2/publications/ic-tr-2010-0607.pdf NicolasRouquette: Thanks Evren! EvrenSirin: There is: Jiao Tao, EvrenSirin, Jie Bao, Deborah L. McGuinness, Integrity Constraints in OWL, AAAI2010 EvrenSirin: http://www.aaai.org/ocs/index.php/AAAI/AAAI10/paper/download/1931/2229 PeterYim: now speaking - Mr. EricChan & Dr. AlanWu (OASIS ICOM TC; Oracle) - "Application of OASIS Integrated Collaboration Object Model (ICOM) with Oracle Database 11g Semantic Technologies" anonymous morphed into TomBrunner FrankChum: Thank you all. Great presentations! Sorry I have to run. RexBrooks: I had a bunch of questions, but they'll wait. Enrico Franconi: cheers IanHorrocks: sorry we ran out of time today. We will have to defer the Q&A and further discussion to the [ontolog-forum] discussion list PeterYim: more questions? ... see: http://ontolog.cim3.net/cgi-bin/wiki.pl?ConferenceCall_2010_08_05#nid2FCF RexBrooks: Perhaps we could schedule a follow-up session dedicated to questions with these panelists and few others? Enrico Franconi: ciao Ian! ZheWu: Thanks Ian RaviSharma: thanks bye. M. Scott Marshall: thanks! bye. PeterYim: Great session ... thank you Ian and all our panelists Andreas Harth: good bye! ZheWu: bye MatthewHorridge: Thanks for listening, Cheers, Matthew PeterYim: thank you all for coming ... let's continue the dialog on the [ontolog-forum] mailing list. PeterYim: if you aren't already a member of Ontolog (which gets you subscribed to the [ontolog-forum] discussion list), please refer to membership details at: http://ontolog.cim3.net/cgi-bin/wiki.pl?WikiHomePage#nid1J PeterYim: -- session ended: 2010.08.05 - 12:32pm PDT -- ---------------
