Today, tomorrow, and the 16th are the fateful days: IBM's Watson supercomputer will go head to head with Brad Rutter and Ken Jennings in this silly, human-devised game we call Jeopardy. It promises to be some kickass TV, at the very least, and a historic event if Watson can prevail over his fleshy competition. The two matches, which are being spread over the three days, were pre-taped, so Ken, Brad, Alex and Watson already know the outcome, but they've done a pretty good job of keeping the secret so far. Hopefully they can keep mum until 7pm-ish this evening (check your local listings for a specific time).
IBM scientists have been working on Watson, which will be the world’s most advanced “question answering” machine, able to understand a question posed in everyday human elocution — “natural language,” as computer scientists call it — and respond with a precise, factual answer. In other words, it must do more than what search engines like Google and Bing do, which is merely point to a document where you might find the answer. It has to pluck out the correct answer itself.
