What is Freebase?

Freebase contains tens of millions of topics, thousands of types, and tens of thousands of properties. By comparison, English Wikipedia has over 4 million articles. Each of the topics in Freebase is linked to other related topics and annotated with important properties like movie genres and people's dates of birth. There are over a billion such facts or relations that make up the graph and they're all available for free through the APIs or to download from our weekly data dumps.
