IBM’s Watson


IBM’s Watson
In February 2011, an IBM super computer named Watson trounced two previous champions of the US trivia quiz show Jeopardy!. Watson parsed natural language questions fast enough to beat the quickest human minds. IBM researchers preloaded the computer with hundreds of millions of pages of data, then armed it with algorithms for searching and ‘reading’ text–separating subjects, verbs and objects. But this was much more than a super-powered Google search. Watson used advanced algorithms to ‘reason’ which of its millions of hypothetical answers was most likely to be true. The ‘face’ behind the

Jeopardy! podium was backed by a roomful of servers, comparing results in fractions of a second until the computer had enough statistical confidence to buzz in. Watson technology is already being considered as the brains behind an automated physician’s assistant.
