I.B.M. plans to announce Monday that it is in the final stages of completing a computer program to compete against human “Jeopardy!” contestants. If the program beats the humans, the field of artificial intelligence will have made a leap forward.
I.B.M. scientists previously devised a chess-playing program to run on a supercomputer called Deep Blue. That program beat the world champion Garry Kasparov in a controversial 1997 match (Mr. Kasparov called the match unfair and secured a draw in a later one against another version of the program).
But chess is a game of limits, with pieces that have clearly defined powers. “Jeopardy!” requires a program with the suppleness to weigh an almost infinite range of relationships and to make subtle comparisons and interpretations. The software must interact with humans on their own terms, and fast.
Indeed, the creators of the system — which the company refers to as Watson, after the I.B.M. founder, Thomas J. Watson Sr. — said they were not yet confident their system would be able to compete successfully on the show, on which human champions typically provide correct responses 85 percent of the time.
I applaud whatever confidence they have, because this seems like quite a mountain to climb:
I would guess the Jeopardy writers could deliver a show that would leave the machine at sea. Metaphorically.
