WHITE PLAINS, N.Y. (AP) — Dr. Watson is accepting new patients.

The Watson supercomputer is graduating from its medical residency and is being offered commercially to doctors and health-insurance companies, IBM said yesterday.

IBM Corp., the health insurer WellPoint Inc. and Memorial Sloan-Kettering Cancer Center announced two Watson-based applications — one to help assess treatments for lung cancer and one to help manage health-insurance decisions and claims. Both applications take advantage of the speed, huge database and language skill the computer demonstrated in defeating the best human Jeopardy! players on television two years ago. IBM said Watson has improved its performance by 240 percent since the Jeopardy! win.

In both applications, doctors or insurance-company workers will access Watson through a tablet or computer. Watson will quickly compare a patient’s medical records to what it has learned and make several recommendations in decreasing order of confidence.

In the cancer program, the computer will consider what treatment is most likely to succeed. In the insurance program, it will consider what treatment should be authorized for payment.
