How is Freebase different from Wikipedia? From Google Base?
Wikipedia and Freebase both appeal to people who love to use and organize information, but the difference lies in the type of information covered, and the way it’s organized. Wikipedia arranges information in the form of articles, while Freebase lists facts and statistics. Freebase information is good not only for people who want to research facts, but also for people who want to use those facts to build other websites and applications. Information in article form can’t be reused in the same way, though it is great for other purposes. Google Base is a database like Freebase, but with much different features and information coverage. The information in Freebase is all shared and collectively editable, with a single topic containing information about its subject across multiple categories.
