Wolfram Alpha

The remarkable (and prolific) Stephen Wolfram has an idea called Wolfram Alpha. People used to assume the “Star Trek” model of computers:

that one would be able to ask a computer any factual question, and have it compute the answer.

Which has proved to be quite distant from reality. Instead

But armed with Mathematica and NKS [A New Kind of Science] I realized there’s another way: explicitly implement methods and models, as algorithms, and explicitly curate all data so that it is immediately computable.

It’s not easy to do this. Every different kind of method and model—and data—has its own special features and character. But with a mixture of Mathematica and NKS automation, and a lot of human experts, I’m happy to say that we’ve gotten a very long way.

I’m still a SearchMonkey guy at heart, so I wonder how much Wofram’s team is familiar with existing Semantic Web research and practice–because at a high level this seems very much like RDF with suitable queries thereupon. If that’s a good characterization, that’s A Good Thing, since practical application has been one of SemWeb’s weak spots.
