The computer "doesn't tell you what to do. It tells you that a treatment is at the top of the list" for a particular patient, says Kris. What makes Watson unique, besides its power (on "Jeopardy!" it sifted through more than 66 million pages of data per second and has only gotten faster since), is its ability to absorb text that isn't in a standardized format, such as a doctor's case notes, and pull out the most relevant ideas. And it learns from experience, says Marty Kohn, IBM's chief medical scientist; the more cases Watson sees, and the more interaction it has with users who point out additional sources Watson should consider, for instance, the better it gets. "It's like teaching someone to be a doctor," says Kris.
