Yes, "evaluating ontologies as pure philosophical theories", because in
systems engineering we mostly use another wording.    (03)

I we try to stay in ontology engineering frame, there is no "evaluation"
process but "verification" (comparing of engineering artifact with its
specification) and "validation" (how engineering artifact fit to serve its
function in client's system). If we buy something, this is regarded the same
way as in engineering (verification to compliance and validation to fit the
purpose).     (04)

If we speaks about "better" that can be clue to what engineers regarded as
trade-off studies. So "ontology evaluation" (what ontology is better) should
mean "ontology trade-off studies". That require first of all knowledge about
overall system-of-interest architecture to determine what one from several
competing ontologies should be implemented as system-of-interest component
as a result of trade-off studies.    (05)

Best regards,
