Re: [ontac-forum] Re: Semantic Layers (Was Interpretation of RDF reification)

My comments had nothing whatsoever against Bunge personally or his
formal systems, which I haven't read and am unlikely to anytime soon. In
my last post you could have replaced "Bunge" with "Azamat" or
"Aristotle" or anyone else that may have a Unifying Framework Ontology.
I was just making the point that *any* Unifying Framework Ontology is
exactly what its acronym stands for - a UFO, an *unidentified flying
object* that no-one will ever agree on for real-world use. Therefore
expecting the Semantic Web to build the provide its users with Unifying
Framework Ontology is an invalid criticism, and also in my opinion UFOs
are a bad idea that current philosophy and psychology (and most of KR)
seemed to have given up on a long time ago for reasons re-iterated earlier.

However, if you still think UFOs are a good idea, the Semantic Web gives
you the formal semantics and language to attempt to define one yourself.
*Just do it* and stop complaining that the Semantic Web has
misinterpreted Bunge/you/Paul Prueitt/whatever. I don't think this sort
of stuff was even on the horizon (again, for good reason I think) when
things were being standardized. If you wish to build a UFO using RDF and
OWL, please look at some of the others like DOLCE, and just do it, and
send everyone an e-mail when it's finished.

In the meantime, in attempt to spare the rest of this listserv, please
respond to me about UFOs, pragmatics, semiotics, reality models,
difference and repetition, obscure philosophers, and such *off-list. *
Please.

               cheers,
