Some comments: (04)
1. It's important to distinguish the research system called Watson,
which was used to play Jeopardy!, from the commercial products
that IBM sells under the Watson umbrella. (05)
2. Machine learning (of various kinds) is important for both. (06)
3. But the research system also used a wide variety of AI techniques,
and many of them do not seem to be used in the commercial products
from IBM (at least not yet). (07)
(But I left IBM many years ago, and I have no information about the
details, other than the publicly available reports.) (08)
4. Generic observation: There are many kinds of ML methods, and
some AI systems use them as integral parts of other methods. (09)
5. The cost of "10 cents per 1,000 predictions" may seem cheap for
"big" predictions, but it might be prohibitively expensive for
a system that integrates learning with certain kinds of NLP
methods or reasoning methods. Such systems might be learning
and predicting with every word of a text or other data item. (010)
