IBM’s computer system Watson vanquished human contests on the TV quiz show Jeopardy! The question now: can it defeat the complexities of the real world?

 

IBM thinks so. The company says it plans to greatly expand its efforts to commercialize Watson by putting another 1,500 engineers and marketers to work on the project. It will also combine Watson with other “cognitive computing” technologies and invest a further $1 billion into a business it says will define the future of how companies use data.
