IBM Watson AI gets draw on Jeopardy!
Tweet
For the last three years, I.B.M. scientists have been developing what they expect 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. Technologists have long regarded this sort of artificial intelligence as a holy grail, because it would allow machines to converse more naturally with people, letting us ask questions instead of typing keywords.
Nobody ever tackled “Jeopardy!” because experts assumed that even for the latest artificial intelligence, the game was simply too hard: the clues are too puzzling and allusive, and the breadth of trivia is too wide.
With Watson, I.B.M. claims it has cracked the problem.
What is Jeopardy?
Jeopardy! is an American quiz show featuring trivia in history, literature, the arts, pop culture, science, sports, geography, wordplay, and more. The show has a unique answer-and-question format in which contestants are presented with clues in the form of answers, and must phrase their responses in question form.
In 15th of February Tuesday's competition began with Jennings (who has the longest "Jeopardy!" winning streak at 74 games) making the first choice. But Watson jumped in with the correct response: What is leprosy, following that with correct answers about Franz Liszt, dengue fever, violin, Rachmaninoff and albinism, then landed on a Daily Double in the "Cambridge" category.
"I'll wager $6,435," Watson (named for IBM founder Thomas J. Watson) said in his pleasant electronic voice. "I won't ask," said host Alex Trebek, wondering with everybody else where that figure came from. Watson answered correctly, Sir Christopher Wren and his total vaulted to $21,035 as the humans stood by stunned.
One answer stumped everyone: "A Titian portrait of this Spanish king was stolen at gunpoint from an Argentine museum in 1987." (Correct response: Philip.) Jennings shook his head. Rutter wrenched his face. Watson, as usual, seemed unfazed.
