2. Query Log Workshop ~ 70 participants Structure: –Research presentations (~20 mins each) –Panel discussion on social issues URL: http://querylogs2007.webir.org/http://querylogs2007.webir.org/

3. Feedbacks Only “authority” facet reflects user ‘s need. Ambiguity and other facets are not. (Amitay, IBM)  Not the user informational needs, but rather the needs for functional helps from search engines. Why don't use clickthrough data, but query string only? (Russell, Google)  valid argument. It may offer more reliable judgment, but that may be used for future augmentation in the future.

4. Feedbacks Authority sensitivity concerns search results. Ambiguity or others: concern the queries?  Answer: does not matter. What we care after all are strategies to help users. Influence of search engines to query log. search engines also complement query logs. For e.g. by analyzing behaviors that search engines offer (query suggestion, query rewriting), perhaps we have more data to analyze the query logs. (Ms. Teevan, Microsoft Research)

5. Future research Jansen: real automated algorithm on query logs –Give some ideas about how the classification will work out. Test out the algorithms. –Have real impacts Other query log sources (e.g. MSN, which is given on an award basis) A demonstration on faceted classification –With functional support from search engines –Extensible for other facets?

6. Other research Papers that I (or you may) think interesting: –Browse this: Exhibit browser: http://people.csail.mit.edu/dfhuynh/projects/w ww-conferences/www-conferences.html http://people.csail.mit.edu/dfhuynh/projects/w ww-conferences/www-conferences.html –Work might be interest our group: Name disambiguation or record redundancy handling Personalized pagerank Chemical formulae IR (?)

7. For students: Volunteer Program Some brief info –In my opinion: a kind of support to students –Well-treated!: good accommodation, flexible time and access to all interesting talks –Opportunities to talk with other researchers / professors/ students –Parties & dinners –WWW’08 in Beijing
