"Jeopardy!" contest Ken Jennings, who won a record 74 consecutive games, refers to his opponent, an IBM computer called "Watson", while being interviewed after a practice round of the "Jeopardy!" quiz show in Yorktown Heights, N.Y., Thursday, Jan. 13, 2011. It's the size of 10 refrigerators, and it swallows encyclopedias whole, but an IBM computer was lacking one thing it needed to battle the greatest champions from the "Jeopardy!" quiz TV show - it couldn't hit a buzzer. But that's been fixed, and on Thursday the hardware and software system named Watson played a competitive practice round against two champions.

(AP) -- The clue: It's the size of 10 refrigerators, has access to the equivalent of 200 million pages of information and knows how to answer in the form of a question. The correct response: "What is the computer IBM developed to become a `Jeopardy!' whiz"?

Watson, which IBM claims as a profound advance in , edged out game-show champions Ken Jennings and Brad Rutter on Thursday in its first public test, a short practice round ahead of a million-dollar tournament that will be televised next month.

Later, the human contestants made jokes about the "Terminator" movies and robots from the future. Indeed, four questions into the round you had to wonder if the rise of the machines was already upon us - in a trivial sense at least.

Watson tore through a category about female archaeologists, repeatedly activating a mechanical button before either Ken Jennings or Brad Rutter could buzz in, then nailing the questions: "What is Jericho?" "What is Crete?"

Its gentle male voice even scored a laugh when it said, "Let's finish 'Chicks Dig Me.'"

Jennings, who won a record 74 consecutive "Jeopardy!" games in 2004-05, then salvaged the category, winning $1,000 by identifying the prehistoric human skeleton Dorothy Garrod found in Israel: "What is Neanderthal?"

He and Rutter, who won a record of nearly $3.3 million in prize money, had more success on questions about children's books and the initials "M.C.," though Watson knew about "Harold and the Purple Crayon" and that it was Maurice Chevalier who sang "Thank Heaven for Little Girls" in the film "Gigi." The computer pulled in $4,400 in the practice round, compared with $3,400 for Jennings and $1,200 for Rutter.

Watson is powered by 10 racks of IBM servers running the . It's not connected to the Internet but has digested encyclopedias, dictionaries, books, news, movie scripts and more.

The system is the result of four years of work by IBM researchers around the globe, and although it was designed to compete on "Jeopardy!" the technology has applications well beyond the game, said John Kelly III, IBM director of research. He said the technology could help doctors sift through massive amounts of information to draw conclusions for patient care, and could aid professionals in a wide array of other fields.

"What Watson does and has demonstrated is the ability to advance the field of artificial intelligence by miles," he said.

Watson, named for IBM founder Thomas J. Watson, is reminiscent of IBM's famous Deep Blue computer, which defeated chess champion Garry Kasparov in 1997. But while chess is well-defined and mathematical, "Jeopardy!" presents a more open-ended challenge involving troves of information and complexities of human language that would confound a normal computer.

"Language is ambiguous; it's contextual; it's implicit," said IBM scientist David Ferrucci, a leader of the Watson team. Sorting out the context - especially in a filled with hints and jokes - is an enormous job for the computer, which also must analyze how certain it is of an answer and whether it should risk a guess, he said.

The massive computer was not behind its podium between Jennings and Rutter; instead it was represented by an IBM Smart Planet icon on an LCD screen.

The practice round was played on a stage at an IBM research center in Yorktown Heights, 38 miles north of Manhattan and across the country from the game show's home in Culver City, Calif. A real contest among the three, to be televised Feb. 14-16, will be played at IBM on Friday.

The winner of the televised match will be awarded $1 million. Second place gets $300,000, third place $200,000. , which has headquarters in Armonk, said it would give its winnings to charity while Jennings and Rutter said they would give away half theirs.

In a question-and-answer session with reporters after the practice round, Rutter and Jennings made joking reference to the jump in technology Watson represents.

"When Watson's progeny comes back to kill me from the future," Rutter said, "I have my escape route planned just in case."

Jennings said someone suggested his challenge was like the legend of John Henry, the 19th-century laborer who beat a steam drill in a contest but died in the effort. Jennings prefers a comparison to "Terminator," where the hero was a little more resilient.

"I had a friend tell me, 'Remember John Henry, the steel-drivin' man.' And I was like ... 'Remember John Connor!'" Jennings said. "We're gonna take this guy out!"

Watch the video on YouTube. It's amazing. My jaw dropped. This really is a big deal. A VERY big deal. I have no idea what algorithms are at play here, but this machine, despite not having a face or a body, somehow falls into the creepy "uncanny valley" of technology. So cold and calculated! Seriously, watch the video.

Hi plasticpowee, next time include the link to help us poor followers.
Cheers,

Well, simple solution. According to every episode of the original Star Trek I've seen, the humans just have to do something illogical or show emotion and Watson will explode.

I don't see how a person can beat a computer or how this can be a fair competition. A person on the show not only has to listen to the question, but a quick reader can read the question before Alex has time to say it and react before he is done. How is the question being input to the computer? If this was fair they would eliminate the board so the contestants can't read the question and the computer would have speech recognition so all of them would have to listen to the question and react to it alone. Even so, a computer specifically designed for this should win easily. I am assuming it was specially designed to do massively parallel searching through its data base. This whole thing sounds like a BS stunt, not a fair competition like the computer chess challenge was or even a big deal like the first poster thinks. And of course the idiot that wrote this article hasn't got the brains to give an pertinent info in it.

Maye the idiot that wrote this article is one of the idiots that run this website WHO DON"T HAVE SENSE ENOUGH TO GIVE US ENOUGH TIME TO EDIT OUT MISTAKES FROM OUR POSTS

Isn't that what humans do too? Or maybe we use a different, more efficient algorithm. I don't see why any particular search algorithm would be more fair than any other. Seems to me that Jeopardy is all about interpretation of language and retrieving the pertinent data from a massive memory bank.

This was amazing. Interestingly, Watson won by $1000, but the last question was worth $1000. You could see Jennings trying to ring in, just not quickly enough. If he would have been just a tad quicker we would be talking about how Ken Jennings beat it.

thales: That's an interesting point, thanks for brining it up. Our brains are VERY good at parallelism, but are very slow. Our brains are like millions and millions of 20 MHz cores compared to IBM's 4000+ 2GHz cores in Watson.
