Software That Reads Harry Potter Might Perform Some Wizardry

Teaching a computer to play Go at a superhuman level is cool, but not especially useful for you or me. But what if a computer could read a few dozen pages of text, like the manual for a new microwave, and then answer questions about how it works? Reading and comprehending text is incredibly difficult for computers, but a Canadian company called Maluuba has made progress with an algorithm that can read text and answer questions about it with impressive accuracy. Most importantly, unlike other approaches, it works with just small amounts of text. It might eventually help computers "comprehend" documents.
