“Man vs. Machine” for $400, Please, Alex

For the first time in history, a computer will compete on Jeopardy!.

Meet Watson.

Watson is considered to be the smartest computer on Earth. Designed by IBM, Watson was created with the specific goal of being able to compete – and win – on Jeopardy!. Starting this Monday, Watson will be competing against the game show’s all-time top contestants, Ken Jennings and Brad Rutter, for a prize of one million dollars. Will Watson be able to succeed?

Creating a computer that can answer Jeopardy!‘s questions seems simple at first – just download every piece of information from every encyclopedia, book, play, movie, Wikipedia, etc. into a database, right? Wrong. This is where the trickery that is Jeopardy! comes in.

IBM had to create a computer that could understand the nuances of human language. Jeopardy! is famous for subtle clues in the questions, wicked wordplay, and requiring contestants to piece together multiple points of information from grammar and syntax in order to find the correct answer. For a computer to win at Jeopardy!, it needs a level of artificial intelligence that has all the data of Google but can “think” like a person.

It took four years, but IBM thinks they’ve done it. Composed of 90 computer servers – basically ten refrigerators of hardware – thousands of algorithms, and over a million lines of new code, Watson is ready. The best Jeopardy! champions give correct answers approximately 90% of the time, and Watson’s is right up there with them.

So will Watson be the next Jeopardy! champion? Possibly. But, then again, Watson’s still known to miss a few. For example, when asked during a practice run “It’s what grasshoppers eat,” Watson replied, “What is kosher?”

Along with watching Watson compete on February 14-16, be sure to watch Nova’s Smartest Machine on Earth, the story of Watson’s creation and how scientists are teaching computers to think and learn.

Who do you think will win this Jeopardy! championship, man or machine?
