Sometimes you don’t know the right search terms to use, but you know it when you’ve found the right web page. This talk describes Personal Eyes, a search add-on that learns to find what you need without you having to know the right search terms. Personal Eyes learns and combines item-based and user-based profiles to produce personalized search results. An item-based profile uses web-page features such as tags, words, hierarchy (e.g. from Google Base), user ratings, and image coefficients. Personal Eyes learns this profile for each user’s interests and uses it to retrieve web pages with similar features. This allows it to also retrieve based on contrary patterns (e.g. any page that Bob does not like, I might like). A user-based profile is based on user features such as age, sex, income, zip code, and web page interests. This allows Personal Eyes to make surprising connections between seemingly disparate web sites by leveraging the idea that users who share some demographics and interests are likely to share others interests. This can be particularly powerful in social networks such as Personal Eyes uses the strengths of one profiling method to fill in the weaknesses of the other to better find what you need.
