I agree that for many purposes related to information integration one
doesn't need a sophisticated logic-based ontology, *if* the users form a
community that has enough communication and common background so that they
know how to interpret the ontology elements. But for the general case,
where human users will be highly diverse and have no communication, it is
important that the knowledge representation itself have enough detail to
make the meanings of the ontology elements unambiguous to the machine as
well as to the human users. That is the case I am concerned with, and that
is the reason why nothing less than FOL will have enough expressivity to be
sure that the data structures are unambiguous even to people with no
background in common with the creators of the data. (03)
