IBM's Watson explained at RPI's EMPAC

After checking out RPI's panels at EMPAC discussing IBM's Jeopardy challenge I must say I'm impressed with what they've done.  There are videos linked at watson.rpi.edu that really give some insight into how Watson works.  The videos are about an hour each (and no, they don't show any of the Jeopardy games), check them out if you're interested in what went on last week.
