Subject Re: Watson powered by UIMA

Greetings all,

The following is a rather nice summary that highlights the use of both
UIMA and Hadoop in Watson.


This also mentions UIMA and Hadoop, and gives some hardware details...


But my favorite part is Prolog. :) Dear old rumply lovable Prolog. PROLOG!

I looked around the apache UIMA site and didn't see anything specific
about supporting Prolog though - is that included in the generic UIMA
or is this some specific IBM add-on?
