Any time the system would need to be employed for a different use, it would have to retrain in the field for which it is intended. For example, if they wanted to use Watson to diagnose illness in real-time for doctors, it would need a substantial training time and reconfiguring to improve accuracy. It would not be as simple as loading a billion medical texts into it's database and sending it on its way.

However, IBM is a lot smarter than I am, and they may train it a different way, but I just can't believe that Watson has a true grasp of linguistics that can translate to any field.

I can see how they would train Watson to answer Jeopardy questions. A clue is "read" and Watson has to figure out whether it's a pun or song lyric or date, etc..., and determine what the question is actually asking and then reference the words and come up with the best answer in context. While this may be great for Jeopardy clues, it does not mean that the type of linguistics Watson has learned will translate to other fields.

I do agree that this is a major step in computing and it is fascinating to see what computer are capable of. In my opinion, this is far more impressive than IBM's chess grandmaster crushing computer as all that had to do was permute an absurd number of moves and determine the best option.

A question for more hardware savvy people. For practical applications where the responses do not have to be quite so instantaneous, what kind of size can the hardware be cut down to? Are all the server racks necessary for computation or is it mostly data storage?
The highlighted parts kind of remind me of another machine.

John Connor... I have come from the future to challenge you to a game of Jeopardy! Prepare to die... I mean lose!

They should sooooo name rename the Watson to Arnold. lol

Answering questions is trivial compared to actually understanding and reacting to a human's emotional responses toward you as a person. They just downloaded all human knowledge, up to that point, into the computer's databanks. This isn't revolutionary. >_>

Actually yes it is. The hardware isn't, the impressive part is the software. Natural Language Processing is an extremely difficult field and Watson is a showcase of how far we've come in it.

This. The ignorance shown by some people in this thread is astounding.

You clearly haven't looked into this at all. All the information Watson has access to is in "natural language," the way humans understand things. The innovation is in the fact that they've coded Watson to be able to interpret questions and look for answers. It's incredible to think of the applications this type of programming can be used for. Medicine, economics, etc. All stand to benefit from Watson greatly.

No no no Wavefunction, you see despite having no actual experience in Natural Language Processing I assure you this is a complete waste of time, money and resources. There is nothing revolutionary about this whatsoever despite your well-reasoned, sound arguments and I say this with my theoretical PhD in Computer Science.
