I agree this is an important problem, but the choice of ontology and how to upgrade from one to another seem to involve so many hard philosophical problems, that the approach taken by the paper, of trying to find specific algorithms that can be used for upgrading ontologies, seems doomed or at least highly premature. I wonder if the author takes that approach seriously, or is only using it for pedagogical purposes.
