How IBM Plans To Win Jeopardy!
wjousts writes "Technology Review is reporting on IBM's plans to take on Trebek at his own game. The 'Watson' computer system uses natural-language processing techniques to break down questions into their structural components and then search its database for relevant answers. A televised matchup with Trebek is planned for next year. 'David Ferrucci, the IBM computer scientist leading the effort, explains that the system breaks a question into pieces, searches its own databases for "related knowledge," and then finally makes connections to assemble a result. Watson is not designed to search the Web, and IBM's end goal is a system that it can sell to its corporate customers who need to make large quantities of information more accessible.'"
Presumably they will either have to take into account the clues that come from the category itself (as in your example) or rig the system by avoiding "trick" categories. It's not an easy problem and it'll be very interesting to see what IBM come up with.
An example from last night, they had a category "Knockouts" in both the first and second round. In the first round, all the answers were hot women (i.e. knockouts!), in the second round all the answers were about boxing. How will Watson deal with this? I don't know.
Yes, there are categories which require the contestant to have an active imagination and it's these categories I wish the article had addressed instead of a vanilla one. And I believe it's these categories that makes Jeopardy fresh and new after decades.
... oh, say Pig Latin!
... as they could make this into an annual competition drawing fans and viewers much like the quest to beat the world chess grand masters.
In retrospect, I should have broke out the conversation into a different post so that this wasn't modded +5 Funny. I'm seriously interested in how IBM plans to address things that require the natural speech recognition of Alex Trebek. Does it take into account other answers in the same category to "catch on" like some contestants obviously do?
Then there's the folks running Jeopardy who could pick some categories that would wreck Watson and give the humans the creative advantage. I hope they exploit this creative ability humans have and write an entire category in
In reality, they stand to have much more to gain if the machine comes close to winning
My work here is dung.
Without speculating on the specifics of tweaking the AI, my guess is that IBM has tried to think through these things. Having put together a few AI bots myself (purely recreationally - you know, just for kicks), I know that I let them play in the real world for quite a while to work out the kinks before unveiling them to nerdy friends and family to show them off and demonstrate just how much time and sleep I'd wasted. My poker-bot played thousands of games in free online rooms before I told anyone that I was even working on him.
IBM has probably been feeding Watson DVR'd episodes for a while now so that they could identify (if not fix) the kind of gotchas that you're thinking about.
