Companies such as True Knowledge are automatically scouring Wikipedia, Freebase, and other databases for "facts" -all painstakingly entered and curated by individual contributors.
The difference is that information on Wikipedia tends to be "unstructured" -ie, buried in text-whereas on Freebase it will be structured, so that each item can be re-used in any context.
两者的不同在于维基百科的信息杂乱无章，淹没在浩渺的文字之中，而Freebase则实现了在上下文中的重运用。
