So it seems to me that alpha is going to try to create mathematical models from unstructured data found on the web and match them with similar models generated from natural language queries entered by the users. I'm sure probabilistic NLP methods are used extensively and I can see maybe how Mathematica can compute these quickly. But what the bleep is the role of NKS? From what little I know, I can speculate that he might have modeled statistical inference using CAs and so can constrain the probability space of matches?? Jebus I need to know more or forget what I know already, anything in between is frustrating.
