IBM's Watson supercomputer turned in an impressive performance on the game show Jeopardy! early last year, beating its two human competitors by a wide margin. IBM assured the Jeopardy! audience that the technology behind Watson could be used to solve a number of problems, including some related to medicine. Now, says Semanticweb.com's Jennifer Zaino, IBM has teamed up with health insurance provider WellPoint to put Watson to the task of helping doctors treat cancer.
