I'm somewhat surprised by the plural - when you develop a
knowledge-based system you'll have one intended model in mind.

As for an elaboration of the point of view proposed by Nicola, see the
recent Ph.D. thesis by Piet-Hein Speel, "Selecting knowledge
representation systems". Piet-Hein compares a number of systems based
on description logic on a couple of criteria, using a particular
ontology as specification of what these knowledge representation
systems had to represent.
