Google Now Scores Higher Than Siri And Cortana On Massive Knowledge Quiz. An AI Breakthrough? Not So Fast.

Apple's famous artificial intelligence agent is eating humble pie today. Ask Siri "Who is smarter, Siri or Google Now?" and Siri obligingly links to an article about a recent 3,086-question challenge that ranked Google Now as the top scorer. Unfortunately for Siri, the quiz had some built-in biases. Designed by the Stone Temple digital marketing group, the purpose of the exercise was to explore a giant, new knowledge base that Google was rumored to be building. Google's mysterious "Knowledge Vault," which was reported by the New Scientist in August, caused a tumult in the SEO community, which lives or dies by its ability to understand how Google prioritizes responses to search queries.
