ISWC Day3
by Naiwen Lin
Hi guys,
This is also my first post. Athens is a nice place and there are some good restaurants (and bars) in downtown. I can see why Vlatko likes here.
Today (Nov 7) is the first day of main conference and we started with Keynote talk 1 by Tom Gruber: “Where the social web meets the semantic web.” After a short break, I wanted to go to the session “Robust and Scalable Semantic Web Technologies” but it was full - some people had to sit on the floor. After the first talk, the staff rearranged the seats so that more people could join. Taowei presented his work of ontology survey. His talk was nice and maybe the best in that session. 
Then I sat in “Semantic Web Service Composition” session. Wow.. I never imagine there are many people working on those topic - web service composition, service planning, workflow, OWL-S, etc. The first talk was given by Freddy Lecue and they proposed a formal model for automated service composition. They followed similarity levels (exact, subsume, plugin, disjoint) by Paolucci et al. and used matrices to calculate all possible I/O matching degree.
Shirin Sohrabi from U. of Toronto presented their work of “Web Service Composition via Generic Procedures and Customized User Preference.” Basically they considered user preferences when performing service matching. And then Ahlem Ben Hassine from Japan gave a talk of “A constraint-based approach to horizontal web service composition.” Vertical composition is the composition of abstract services and horizontal composition is that of concrete services. They considered user preference, QoS, volatile information and other real-time factors.
Tonight was posters reception. Taowei looked very very busy since his poster was located in the middle of the hall. It seemed my teeth problem is getting worse so I couldn’t join the dinner with people after posters reception. Now I’m looking forward to tomorrow’s “Semantic Web Services” session. =)
