Conference Call Details    (2FA4)

Attendees:    (2FB3)

Agenda & Proceedings:    (2F51)

Abstract: This is the second of our two back-to-back sessions devoted to OWL 2. Our session chiar, Professor IanHorrocks (co-chair of the W3C OWL 2 Working Group) has brought together an expert panel of OWL 2 researchers and developers to show us some of the state-of-the-art in OWL 2 tools and applications. Again, we will have about 30 minutes for open discussion after all the panel briefings. The panelists and their presentations will include:    (2FBV)

	PeterYim: now speaking - Mr. MatthewHorridge (U of Manchester) - "The OWL API: a Java API for 
	working with OWL 2 ontologies"    (2G24)
	FrankChum: Are the versions backward compatible?    (2G25)
	Axel Polleres: What's the relation OWLAPI vs dig regarding the reasoning interface?    (2G26)
	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    (2G27)
	PeterYim: now speaking - Dr. TimRedmond & Dr. TaniaTudorache (Stanford-BMIR) - "The Protege Tool 
	Suite for Editing OWL Ontologies"    (2G28)
	NicolasRouquette: It is often difficult to tell which ontology asserted a particular axiom and which 
	axioms a particular ontology asserts.    (2G29)
	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.    (2G2A)
	PeterYim: now speaking - Dr. AndreasHarth (The NeOn Project; Institute AIFB, Karlsruhe Institute of 
	Technology) - "The NeOn Toolkit"    (2G2B)
	PeterYim: now speaking - Dr. EvrenSirin (Clark & Parsia) - "Pellet: OWL 2 Reasoner"    (2G2C)
	Axel Polleres: afraid I need to run, thanks for the interesting talks!    (2G2D)
	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)    (2G2E)
	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)?    (2G2F)
	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?    (2G2G)
	EvrenSirin: Pronto uses lexicographic entailment algorithms to perform default probabilistic 
	reasoning    (2G2H)
	EvrenSirin: The semantics is based on first order probabilistic logic    (2G2I)
	EvrenSirin: The computation of probabilistic inferences has several steps and involves solving 
	linear equations among others    (2G2J)
	Enrico Franconi: @Evren, which is the reference for the integrity constraint validator? Is it just 
	what we can find on the web page?    (2G2K)
	EvrenSirin: @Enrico, longer technical report has several corrections: 
	http://www.cs.rpi.edu/%7Etaoj2/publications/ic-tr-2010-0607.pdf    (2G2L)

	OWL, AAAI2010    (2G2N)

	Enrico Franconi: cheers    (2G2T)
	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    (2G2U)
	PeterYim: more questions? ... see: 
	http://ontolog.cim3.net/cgi-bin/wiki.pl?ConferenceCall_2010_08_05#nid2FCF    (2G2V)
	RexBrooks: Perhaps we could schedule a follow-up session dedicated to questions with these panelists 
	and few others?    (2G2W)
