Hello All,
Here's a thought I have not seen discussed so far in the various
excellent threads about Watson.
Watson is of course a major achievement, as it demonstrated by
comfortably winning Jeopardy.
It's now official that IBM sees Watson has having potential in
Medicine -- it could read the biological-medical literature and
outperform the Doctors.
However, for these purposes, there's a key difference between
Jeopardy and Medicine.
In Jeopardy, humans know the right answers -- the city of
Toronto is not in the USA.
In Medicine, humans don't have consensus answers to new questions
(e.g. What is the best treatment for multiple sclerosis). So,
whatever algorithms Watson uses will lead to new medical knowledge
that humans cannot easily check by thought experiments.
Perhaps evidence-based medicine over structured data may help to
to check Watson's new medical knowledge?
Of course, if Watson could produce English explanations of its
answers, that could help too.
It appears that Watson can give you a lot of insight into how it
arrived at an answer including the various parallel processes that
were done.
It probably can do a much better job of this than most humans since
we quickly forget the bad ideas and fruitless paths whereas Watson
remembers them all.

Just a Friday afternoon thought.
