Current search engines use keywordsYou might get 104M pages backYou can only look at one page at a time.Hard to aggregate and visualize resultsHow can we ask more complicated questions, and get real answers?

Key ConceptsStructured knowledge leads to better search and more accurate information retrieval over sets of related dataBest knowledge repositories will be user-extensible, but leverage form fillable fields as defined by typesThe W3C’s Semantic Web will make sure that info doesn’t have to be centralized!
