The amount of use a knowledge representation system receives depends on more than just the theoretical suitability of the system. Some critical determiners of usage have to do with issues related to the representation formalism of the system, some have to do with non-representational issues of the system itself, and some might be most appropriately labeled public relations. We rely on over eight years of industrial application experiences using a particular family of knowledge representation systems based on description logics to identify and describe usability issues that were mandatory for our application successes.
