To create Watson, IBM had to engineer analytics technology that could sift through the equivalent of one million books and find a single correct answer—all in less than three seconds. What’s more, the computer had to be able to understand subtleties in the English language, such as puns.

Rod Smith: There were two things we really leveraged in Watson. First we figured out how to get Watson to take questions apart and look at many interpretations.

Then, in parallel, he kicked off searches on lots of different search engines.

As information came back, it was weighted—it had a probability of being correct. That probability was based not only on the information, but also
