The article at :

http://www.linuxfordevices.com/c/a/News/IBMs-Watson-wins-Jeopardy-practice-round/?kc=rss

mentions:

"Under the "hood," Watson is all open-source, using Eclipse as the tools
platform along with Apache's Hadoop and Unstructured Information
Management Architecture (an "IBM Research creation") to analyze
unstructured data, said Spang."

googleing for "Unstructured Information Management Architecture" you can find:

http://domino.research.ibm.com/comm/research_projects.nsf/pages/uima.index.html

http://uima.apache.org/

There is an introduction starting at:

http://uima.apache.org/doc-uima-why.html

This could be the kernel of Watson and the rest are extras added for the show. Analyzing this information can take months but it looks very promising. (Unfortunately most is in Java.)
