Watson Jeopardy Competition Review

I saw the first half hour of this competition between two former Jeopardy champions and the Watson IBM Supercomputer.  . Far too small a sample to make much of a conclusion about the generality of the technique. Watson did not have a connection to the Web, so no outside help. Though very large databases could have been downloaded and indexed ahead of time. Watson was very impressive, getting what I perceived to be very hard questions and missing some easier ones. Most impressive. the interpretation of natural language. Also revealed, the use of numerical confidence measures to determine when a set of possible answers could be narrowed to a single result.   Would like to see many more examples to see how this might be used say in an interface within the enterprise to answer questions that included both internal and expernal information, using informal business language.  IBM's Watson site.
