Verifying Reasoner Correctness - A Justication Based Method

DL reasoners are complex pieces of software that work on even more complex input which makes manual verification difficult. A single ontology can have hundreds or thousands of classes and thus its classification involve an unsurveyable number of subsumption tests. We propose a new method for debugging classification across multiple reasoners which employs justifications generated from the set of entailments that reasoners disagree upon to determine the cause of the disagreement.
