Researchers at IBM have launched a billion-dollar project to develop a machine that can compete in the quiz show Jeopardy--and win. Early next year, if all goes well, the machine will face off in a nationally televised match against two kingpins of trivia: The reigning champion of Jeopardy, still to be determined, and the game's greatest all-time winner, Ken Jennings. Final Jeopardy, by journalist Stephen Baker, carries readers on a captivating journey from the IBM labs to the showdown in Hollywood. The story features brilliant Ph.D.s, Hollywood moguls, knowledge-obsessed Jeopardy masters--and a very special collection of silicon and circuitry named Watson. It is a classic match of Man vs. Machine, not seen since the chess-playing computer Deep Blue bested the world's reigning grandmaster, Garry Kasparov. But Watson will need to do more than churn through chess moves or find a relevant Web page. It will have to understand language, including puns and irony, and master everything from history and literature to science, arts, and entertainment.
