An Insight Into Watson's Brain

I found a neat article briefly discussing how Watson derives solutions. A much more in-depth analysis can be found here. It's amazing to see so many different aspects of computer science come together to create something like Watson. Most, if not all, the techniques used by Watson have been around for years now, but Watson is probably one of the first to combine them all in such a powerful way. It probably helps that it runs on specialized (and expensive) IBM hardware. The impressive performance of Watson is a great milestone in artificial intelligence and computer science. It's a good time to be in CS. :P
