No, definitely not. Pseudo-bayesian classification as used by the more
optimistic spam-filtering folks is pretty crappy at the best of times,
and it's really unusuable for more than 3-4 categories.

There are natural language analysis techniques that'll do this sort of
thing, but they're in the realms of research projects, not canned
tools.

Cheers, Steve
