A new system would rank pages on their veracity as compared to whatever internet factoid google deems truthy.
So how would it work? The new algorithm draws on Google's "Knowledge Vault" -- a collection of 2.8 billion facts extracted from the Internet.
By checking pages against that database, and cross-referencing related facts, the research team believes the algorithm could assign each page a truth score. Pages with a high proportion of false claims would be bumped down in the search results.
