Computer fact-checker and news reader grab attention online

Three research papers about the potential power of computers to outsmart us -- while comforting us with cute pet videos -- caught the attention of the online science community this week. Researchers shared a PLoS ONE paper about a computational fact-checker that can sort truth from fiction; an arXiv preprint about a computer program that can read and comprehend news stories; and a study of the psychology of watching Internet cat videos. In the PLoS ONE paper1, researchers at Indiana University in Bloomington mined Wikipedia's information boxes, which summarize the key facts in most Wikipedia entries, to create a'knowledge graph' of 3 million people, places and things. The resulting algorithm could then use that knowledge to gauge the truth of simple statements that were presented to it, such as "Rome is the capital of Italy", with nearly the same accuracy as human fact-checkers. The researchers acknowledge that the source material is not 100% reliable, something that online commenters also noted.
