Ontology Revision as Non-Prioritized Belief Revision

Ontology revision is the process of managing an ontology when a new axiom or fact would render it inconsistent. So far, the AGM approach to belief revision has been adapted to work with ontologies. However, when multiple sources are contributing uncertain knowledge about a static domain, an approach that doesn’t give priority to incoming information and allows to recover previously discarded axioms is more suited. We describe an ontology revision framework that links symbolic and numerical techniques to allow the consistent evolution of an ontology from the contributions of multiple potentially unreliable sources. Key words: Ontology revision, belief revision, OWL.
