Meet Dr. Watson: 'Jeopardy!' Champ Takes on Cancer and Land Use

IBM's Watson may be most famous for winning at the game show "Jeopardy!" In a room at IBM offices, software developers and business customers can query the famous computer and see a demonstration of its work as a research partner in fields ranging from land use to medicine. The room itself has a display wall on one side and a touch screen in the center and near the window. In a recent demonstration of how the machine approaches search queries, Rachel Liddell, a "Watson Experience Leader," used the central touch screen to search through a series of TED talks. As she touched the screen to look up lectures on human psychology, Watson created a set of associated topics, such as "education," and touching one of those words generated more specific topics that appeared in the talk.
