Dagstuhl day 1

Dagstuhl logoFirst day of the Dagstuhl seminar is now over. This is a good opportunity to tell you more about this unique place.

The idea of Dagstuhl seminars is to bring top computer scientists in a particular field from around the world and have them communicate with each other and do research. This communication is promoted by several means: First, all participants stay in the same building with hotel-style accommodations. Further, there is a coffee room, game rooms, a piano room and more informal activities to allow people to communicate. However, the most direct effort to promote communication is the random seating during lunch. The idea is to force people to talk with people outside their own narrow field of research.

Today I also gave my talk titled "An Axiomatic Approach to Personalized Ranking Systems". Several people gave me compliments about my talk and many asked questions both during and after the talk. Also, it turned out that we are not the only ones mining eBay for reputation data, which means we might be able to get the data from someone else instead of gathering it ourselves.

At dinner I was seated with several people I know, and one person from Stanford who I didn't know before. We had a nice conversation, and we have then retired to our rooms. There are no formal plans for the evening, so I plan to go online and maybe look around the premises here at Dagsuthl. All in all, I like it here.
