- Basically, to evaluate a stated fact, you only need two things: the fact and a reference work to compare it to. Google already has the beginnings of that reference work, in the form of its Knowledge Graph — the thing that displays “August 15, 1990” when you search “Jennifer Lawrence birthday,” or “American” when you search “Obama nationality.”
- Google culls those details largely from services like Freebase, Wikipedia and the CIA World Factbook; a separate, internal research database, called Knowledge Vault, can also automatically extract facts from the text on Web pages. Whichever database we’re talking about, Google structures these ‘lil factoids as things called “knowledge triples”: subject, relationship, attribute.
- To check if a fact found in the wild is accurate, all Google has to do is reference it against the knowledge triples in its giant internal database. And to check whether a Web page or a Web site is accurate, Google would just look at all the site’s knowledge triples and see how many don’t agree with its established body of facts.
Google has developed a technology to tell whether 'facts' on the Internet are true
