Mark Meiss presented our work on Web click traffic analysis at the First International Conference on Web Search and Data Mining (WSDM 2008) on the beautiful Stanford campus. His talk was very well received, as reported in Greg Linden’s blog. The quality of the conference itself was very good, with several excellent presentations. Those I found most interesting were Qiaozhu Mei’s talk on search log entropy, Nick Craswell on click position bias, Carlos Castillo on social media, and Paul Heymann on social bookmarks. I think future WSDM conferences should have an award for the best-delivered talk. This year I would have voted for Carlos Castillo. The next WSDM will be in Barcelona.
