the IBM. Watson won the second match against the strongest players in the intellectual game Jeopardy ( the Russian equivalent - ' Jeopardy '), thus becoming the strongest in the three-day contest, the BBC reported.
On the sum of two games Watson earned 77,000 dollars, more than three times ahead of the strongest participants in Jeopardy - Ken Jennings (Ken Jennings) and Brad Rutter (Brad Rutter). ' Welcome to our new computer overlords ...
In the first game of the tournament Watson defeated rivals: only in the first round Rutter was on par with the computer system to answer questions from different fields of knowledge.
After the first round lead of the second game took Jennings, who collected 8.6 thousand dollars, Watson at this point in his account had 4.8 thousand dollars, and Rutter - 2,4 thousand dollars. In the second round, the computer beat Jennings ( 23.44 thousand dollars from Watson against 18.2 thousand dollars from Ken ).
In the final round, consisting of one question to be appointed by the players value, the computer did not leave people a chance to win. Even if Jennings would be played all in and won, and Watson, on the contrary, made a mistake in the ' piggy bank ' cars would be a dollar more.
However, all three participants responded to the last job correctly ( Jennings put a thousand dollars ).
As in the previous game, Watson often his opponents mistaken: he three times gave the wrong answer. Twice wrong Rutter, and only once incorrectly answered Jennings. However, the total number of correct answers out of the competition Watson - 29, against 18 at the Jennings and 13 from Rutter.
The outcome of the tournament may well have been different if the people a little more luck. Under the rules of Jeopardy, in the first two rounds of the game three points, like the final task, have an open price - the player who got a question, he may assign its price within the available amount in the account. In the first round thanks to the rate of all- silicon Jennings managed to get around an opponent ( the two remaining issues to be appointed by the cost went to the computer, which made a rather cautious rate).
As written in the book 'Final Jeopardy' journalist Stephen Baker (Stephen Baker), one of the previous tournament training games because of large bets on the fallen value of the open issues with Jennings managed to beat Watson.
Demonstrated machine in the course of the tournament ' knowledge' were obtained by indexing a large number of texts. During the game Watson was acting in standalone mode, without using external information resources and computer networks.
The success of Watson in Jeopardy tournament was evidence of progress in the field of automatic processing of requests formulated in natural language.
Another brainchild of IBM - a supercomputer Deep Blue - the famous chess match held in 1997, defeated world champion Garry Kasparov.
According to representatives of IBM, technology, which uses Watson, can be used, particularly in the professional activities of doctors ( to aid in diagnosis ) and lawyers ( for the analysis of legal texts and legal documents in preparation for the examination of specific cases ).
According to Information Week, IBM and the company Nuance, which specializes in speech recognition technology, signed an agreement to develop a system that will assist physicians in diagnosing. It is assumed that the computer will be able to prepare an advisory opinion, extracting information from existing medical databases and electronic records of patient health.
Creation of the first commercial products based on technologies Watson for use in medicine is planned for two years.
