There is some thing else I would like to point out as well , IBM folks on this thread can answer the question. This is regarding the "user modeling service" of Watson. I spoke to a couple of IBM folks and asked what are some of the coolest Apps they had seen that was built using Watson - and someone mentioned the following MSNBC article . It's Watson perception about the State of the Union Speech .What the user modelling service does - is to take text as input and sentiment analyze it ( and give outputs around it)

What the folks @ MSNBC did was to pass the last 10 SOTU speeches to Watson and collate the results over a graph.

But, Here is why I have trouble believing Watson's perception. Try passing the following input to Watson - (or any other gibberish)

Its plain gibberish , and you still get some results. I tried passing other text transliterated to English and Watson still gives results like this. I would expect it to atleast call it out as gibberish-text.
