We've been talking plenty about Google's efforts in the search space lately, and today's news holds another big announcement for us. Google has announced that its Knowledge Graph, which works behind-the-scenes with Google Now, has been expanded to include support for a handful of new languages. The Knowledge Graph is a way for Google to deliver not only the information you're looking for when you search, but also extra information that's relevant to your query.

Google is already pretty good at delivering information right when we ask, but naturally, it wants to get better. It wants to get so good, in fact, that it's been looking into what sort of questions people have but never think to search for. That's according to MIT Technology Review's Tom Simonite, who spent three days participating in Google study that aimed to find out what was on his mind.
