What is Watson ? (not ‘who’) |
I first heard about IBM’s challenge to build a computer system which could compete at the game of Jeopardy. Knowing the types of questions, the many ways the clues are hidden in the questions, and the enormous breadth of categories, I was definitely curious to see the path of the work. It’s here. It’s called Watson. And it’s VERY COOL.
The producers of “Jeopardy!” have agreed to pit Watson against some of the game’s best former players as early as this fall. To test Watson’s capabilities against actual humans, I.B.M.’s scientists began holding live matches last winter. They mocked up a conference room to resemble the actual “Jeopardy!” set, including buzzers and stations for the human contestants, brought in former contestants from the show and even hired a host for the occasion.
Technically speaking, Watson wasn’t in the room. It was one floor up and consisted of a roomful of servers working at speeds thousands of times faster than most ordinary desktops. Over its three-year life, Watson stored the content of tens of millions of documents, which it now accessed to answer questions about almost anything. (Watson is not connected to the Internet; like all “Jeopardy!” competitors, it knows only what is already in its “brain.”)

How Watson works is a great read. Watson is not infallible. As noted in the NYT article, one day it won four of six games and another day it won only three of seven games and in one case, had no winnings at all.
When Watson is playing a game, Ferrucci lets the audience peek into the computer’s analysis. A monitor shows Watson’s top five answers to a question, with a bar graph beside each indicating its confidence. Ferrucci’s team has programmed Watson generally not to buzz until it arrives at an answer with a high confidence level.

I have no desire to play Jeopardy against Watson … because I’m not very good at Jeopardy. But I am looking forward to watching the game!
