Actually, it is the intersection of statistical and logical techniques on
the semantic web that are most interesting to me. Consider healthcare and
biomedical research, we have lots of use of statistics, as well as
sophisticated ontologies such as SNOMED.

If you think of the Web as an amorphous distributed database, it will be
shared ontologies that will best give it the structure that will allow
meaningful datamining -- databases generally require schemas to do anything
useful. Similarly statistics are best applied to (distinguish) classes of
things.
