Jeopardy: Man vs. Machine

For the first time, an IBM computer against the best players in the first inning and Jeopardy holds man and machine tie. IBM prepares the game for years. It puts forward Watson, a system of artificial intelligence capable of understanding a question and answer (see "A computer will play Jeopardy"). The task is difficult because not only must understand the syntax, but the wordplay and the complexity of the issues that are given, search through its database to output the correct answer.

Big Blue can already be welcomed, because his performance is impressive. Opponents of the system are the best American players of all time. Brad Rutter is the biggest winner in terms of gain with 3.3 million. Beside, there Ken Jennings, the only man to have won 74 games in a row. Watson has started on a flying ahead of its competitors.

Mr Rutter was then caught up. He is tied with Watson, both with $ 5 000. Mr. Jennings is a distant second with $ 2 000. Watson has nevertheless made some missteps. He repeated the wrong answer to one of its competitors and gave the wrong answer. There are still two rounds to decide between man and machine.

The winner will receive the sum of one million dollars. The game has already been recorded last month in the IBM research center in New York, but nobody knows the outcome. Many have in mind the chess game won by Gary Kasparov against IBM in 1997. This is another step equally symbolic in the development of artificial intelligence.
