The power of learning categories (from features, because that is how
machine learning is done) has of course been my point throughout these
threads.    (01)

With one only proviso, that the learning must be ad-hoc (the emphasis
on the process, not on any one result.)    (02)

As I mentioned earlier, a form of this was also tried as a way to
learn grammar in the '30s and '40s. It fell out of favour because it
was found impossible to get a single consistent set of categories. A
result very like the impossibility of a single Foundation Ontology we
have been discussing.    (04)

To the best of my knowledge there has been no systematic exploration
what can be achieved by "data mining" if the assumption of a single
consistent set of categories is abandoned and the focus put instead on
selecting categories appropriate to a problem to be resolved. Although
the success of indexed search could be seen as a form of this.    (05)

I think it is far more important to abandon this assumption of a
single consistent set of categories than to explore different feature
sets, although different feature sets have their place.    (06)
