SWSA F2F New York City 23-24 May 2004 Plenary session introductions logistics SWSA breakout Participants: Mark Burstein Mike Dean Tim Finin Paul Kogut Massimo Paolucci Robert Patton Norman Sadeh Amit Sheth Michael Stollberg Mike Uschold Kunal Verma, UGa Michal Zaremba Requirements document nearly ready for initial release to Industrial Partners and other groups everyone should review tonight for discussion tomorrow Amit Sheth: METEOR-S demo (presentation materials in ZIP) QoS ontology parallel efforts WSDL 2.0 Semantic Web mapping METEOR WSDL-S WWW2004 paper on annotation domains, e.g. supply chain B2B MWSDI modelling tool Flow Layer using colored Petri Nets BPEL requires endpoints use abstract endpoints Mark: architecture requires more than protocols - needs internal representation using ontologies that allows you to specify your requirements for use of the service - step 1 for Semantic Web Services end-user experience, e.g. Grid community Tim Finin: cited Fujitsu College Park Task Computing work with Jim Hendler's MINDSWAP lab Mark: perhaps architecture for Semantic Web, not just Semantic Web Services, to include versioning. Massimo: Amazon interface broke because Amazon.com changed its WSDL - a possible use case Tim Finin: Trading Agent Game (TAGA) (presentation materials in http://www.daml.org/services/swsa/working/taga.ppt ) MB: Consider for use as a thought experiment/use case for considering interactions between SWS protocols. http://taga.umbc.edu AAMAS competition travel agent with 8 customers with different preferences agent with most money wins well-defined APIs and simple XML encodings OWL used for everything OWL-S an improvement over what was originally in DF SL (like KIF) typically used a content language assumed everyone using the same ontologies 2 types of auctions: Priceline and Hotwire OWL has good mechanisms for mixing multiple ontologies within content Norman: rules are pervasive implemented in Jade and April (Language from Frank McCabe at Fujitsu) UMBCTac.agentcities.net further experiment might be Norman Sadeh's supply chain management translation use case lots of effort required for SAP and Rosetta updates Norman: Covisant automotive exchange common use cases travel B2B pervasive computing eBay use of Web Services WWW2004 presentation 40% of items are submitted through their applets still moving to WSDL developer.ebay.com [use of P3P for specifying service privacy requirements?] Chris Bussler's proposal without translation, limited to islands of agreement discovery probably low-hanging fruit, but not highest payoff translation/mapping/versioning may be highest payoff Paul Kogut: recursive definitions / dogfooding e.g., defining interface to CMU Matchmaker in OWL-S Tim: FIPA means of defining ontology translation (e.g. lossless, etc.) inactive FIPA Ontology Technology Committee Mike Uschold: Natasha Noy noticed relationship between mapping and versioning - mapping is generally easier between versions of the same ontology Norman: nice if document could become journal or magazine article Mark: also W3C submission Robert: Oak Ridge sponsoring Semantic Web track at HICSS - early January http://www.csm.ornl.gov/~v8q/Homepage/SemWebCall%20for%20Papers%202005.htm Thomas Potok and Mark Elmore are chairs tomorrow mapping roadmap ---------------------------- May 24 Morning Talks by Michael Stohlberg DERI/Innsbruck on WSMO/WSMX Presentation materials in: http://www.daml.org/services/swsa/working/wsmo-SWSI-briefs-May04.zip Mark Burstein on semantic translation for dynamic service invocation http://www.daml.org/services/swsa/working/burstein-SSS04-mapping.ppt Massimo Paolucci, Katia Sycara on alternative architectures of dynamic discovery/matchmaking Afternoon Discussions of SWS Roadmap (near/long term technical issues and features to address) SWSA Task plan for the remainder of the year. Both of which are summarized in the opening/closing slides at http://www.daml.org/services/swsa/working/SWSAF2F-NYC-May04.ppt
