The Use of the Belief Revision Concept to Ontology Revision

Ontology is a formal explicit specification of shared conceptualisation. Ontology revision refers to revising the ontology as a result of learning or when new knowledge is gained. This paper discusses the possibility of using the concept of belief revision as a basis for ontology revision. Belief revision is concerned with the approach of updating and revising a belief set so that it remains consistent when new information is received. The consistency issue is important to ensure that it does not cause inconsistent beliefs or contradicts with existing beliefs. We propose to use the expansion, revision and contraction operators of belief revision to revise ontology. The conceptual framework of these operations will be presented.
