Nicola Guarino summed this up nicely: (02)
"a conceptualization is a set of extensional relations describing a
particular state of affairs, while the notion we have in mind is an
intensional one, namely something like a conceptual grid which we
superimpose to various possible state of affairs" (03)
Questions: (04)
Do hypothesis have a legitimate right to exist in a formal ontology or
should the ontology be used solely as a factual basis to feed some form of
inference machine to form further hypothesis? (05)
Should ontologies be strictly limited to only "universal truths" and
"aspects" (assuming they are represented as a contextual viewpoint) or
should they include probabilistic relationships? (06)
I have heard arguments on both sides for these questions. Too bad most
ontologies don't define ontology. (07)
