  2. PhD, XQFT and reality • Monolithic • Having a massive, unchanging structure that does not permit individual variation. • Got me my PhD • Atheist • as a philosophical view, is the position that either affirms the nonexistence of gods or rejects theism. • Ended up in XQFT • Agnostic • Greek α-γνωστικισμός, "without gnosis”, “without knowledge") is the philosophical view that the truth value of certain claims is unknown or inherently unknowable (!) due to the nature of subjective experience perceived by that individual. • Having fun… until Monolithic Microsoft

  4. Now, closer to the people, further from THE truth • No XML! • Lots of data and opinions • Collaborative tagging sites: Flickr,del.icio.us, etc. • Collaborative reviewing sites: Y! Movies, Y! Local, etc. • Efficient and effective recommendation platform • Serve (socially!) relevant content to users • Better recommendations • relevance determined by people who matter to you! • social context, explanation, diversity, temporality, etc • Characterize users’ interests and connections • I enjoy watching Schindler’s list with my parents • and very different movies with my boyfriend!

  5. It’s a beautiful world about philosophy and people • … and a little bit about publishing papers: • Social Information Processing Symposium • http://www.isi.edu/~lerman/sss07/ • x.qui.site recommendations in del.icio.us (with Cameron Marlow, Julia Stoyanovich and Cong Yu) • reviewing the reviewers: extracting biases (with Andrei Broder and Alban Galland) • … and quite a bit about internal impact: • extensions to the Vibes platform • Y!Travel, Real Estate, Shopping, Autos, News, …

  6. and now… show me the money • A bidding language for advertisers • A standard • Banner ads • I am Nike: Target soccer moms who live in the Bay area and keep in mind that they would not like to see the same ad more than 5 times, preferably in the afternoon (after their kids soccer!), and remember, I don’t want to be shown with Adidas • I am a language school: Target 25-35 year olds who live in the tri-state area, and remember, I can only pay $1000 for 5000 impressions. • With David Pennock and Sebastien Lahaie
