I've worked with some people from IBM, doing some cancer analyses with Watson. I think the goal was to compare US/EU results(cancer get different treatments in different regions I guess). We "fed" Watson with actual patient data / diagnostics(getting/selection data was my job) and reviewed the resulting suggested treatment plans. Watson would suggest different plans, with results stats, links to pubmed, datasets etc. I'm no medic, but it looked nice. I wouldn't mind a "second opinion" like that.
