Recap: IBM’s Watson Dominates at Jeopardy!

“I, for one, welcome our new computer overlords.”

So wrote Ken Jennings as part of his correct response to the Final Jeopardy! clue in tonight’s final game between Ken Jennings, Brad Rutter, and the newcomer, IBM’s Watson.

Though it didn’t do as well today as it did in match 1, Watson had another impressive showing in Game 2, earning $41,413 and combined with his $35,734 in game 1, won the two-day affair with combined winnings of $77,147. At the end of the Double Jeopardy! round, Ken Jennings computed that he wouldn’t be able to beat Watson even if Ken wagered it all, so he wagered conservatively in Final Jeopardy!. The category was 19th Century  Novelists and the clue was:

“William Wilkenson’s ‘An Account of the Principalities of Wallachia and Moldavia’ inspired this author’s most famous novel.”

All three contestants got the right answer: Bram Stoker, who wrote Dracula (I got it right at home, playing along). In the end, Ken Jennings wound up with $24,000. Brad Rutter came in third with $21,600 in winnings. Of course, IBM’s Watson was playing for charity, and the cool $1,000,000 prize will be split between World Vision and World Community Grid.

Overall, I was very impressed with Watson’s showing. And yes, I was wrong with my prediction that I made last week. The last three days on Jeopardy! have been a blast.

So what’s next for IBM? According to the New York Times:

For I.B.M., the future will happen very quickly, company executives said. On Thursday it plans to announce that it will collaborate with Columbia University and the University of Maryland to create a physician’s assistant service that will allow doctors to query a cybernetic assistant. The company also plans to work with Nuance Communications Inc. to add voice recognition to the physician’s assistant, possibly making the service available in as little as 18 months.
