Abstract:Debugging OWL ontologies can be aided with automated reasoners that generate entailments; including undesirable ones. This information is; however; only useful if developers understand why the entailments hold. To support domain experts (with limited knowledge of OWL); we are developing a system that explains; in English; why an entailment follows from an ontology. In planning such explanations; our system starts from a justification of the entailment and constructs a proof tree including intermediate statements that link the justification to the entailment. Proof trees are constructed from a set of intuitively plausible deduction rules. We here report on a study in which we collected empirical frequency data on the understandability of the deduction rules; resulting in a facility index for each rule. This measure forms the basis for making a principled choice among alternative explanations; and identifying steps in the explanation that are likely to require extra elucidation.
