In 2011, the IBM Watson computer was
able to beat the top-earning human
winners on the trivia game-show
âJeopardy!â Presenter Tony Pearson,
author of "How to Build Your Own
Watson Jr. in Your Basement," will
explain how the IBM Watson system
was put together, how it works, and
what examples of text mining and big
data analytics means for society as we
apply technology to meet
tomorrow's challenges.

novel architecture, we achieved very high levels of
Precision and Confidence over a huge variety of
content.
⢠Speed â By optimizing Watsonâs computation for
Jeopardy! on 2,880 POWER7 processing cores we
went from 2 hours per question on a single CPU to an
average of just 3 seconds.
⢠Results â in 55 real-time sparring games against
