There isn’t enough Data to power Wolfram Alpha

Stephen Wolfram, the CEO of Wolfram Alpha, explains the algorithmic capabilities behind Wolfram Alpha. It is powered by massive data sets — so much that it cannot be simply retrieved from the internet. Stephen Wolfram even states that “there actually isn’t enough data on the Web to get all of the things we need.” To make sense of the data, Wolfram Alpha must both compute custom answers (and not simply search for them), and of course, natural language processing plays a major role in understanding what’s asked.
