Revising Description Logic Terminologies to Handle Exceptions: a First Step

Abstract:
We propose a methodology to revise a Description Logic
knowledge base when detecting exceptions. Our approach relies on the methodology for debugging a Description Logic terminology, addressing the problem of diagnosing incoherent ontologies by identifying a minimal subset of axioms responsible for an inconsistency. In the approach we propose, once the source of the inconsistency has been localized, the identied axioms are revised in order to obtain a consistent knowledge base including the detected exception. To this aim, we make use of a nonmonotonic extension of the Description Logic ALC based on the combination of a typicality operator and the well established nonmonotonic
mechanism of rational closure, which allows to deal with prototypical properties and defeasible inheritance.
