An ontology is a representation in a logical language of a domain. An ontology can change; a changing ontology can became inconsistent, thus preventing its further use for machine reasoning. We analyze what an ontology is from a computer science perspective, why it can change, and how to manage inconsistency in changing ontologies. The belief revision approach is not the only possible approach to maintain consistency during evolution: an ontology reengineering can rationally prefer to discard incoming information, or to refine the nature of conflicting implication axioms to derive meaningful answer from inconsistent ontology using paraconsistent logic.

Abstract

An ontology is a representation in a logical language of a domain. An ontology can change; a changing ontology can became inconsistent, thus preventing its further use for machine reasoning. We analyze what an ontology is from a computer science perspective, why it can change, and how to manage inconsistency in changing ontologies. The belief revision approach is not the only possible approach to maintain consistency during evolution: an ontology reengineering can rationally prefer to discard incoming information, or to refine the nature of conflicting implication axioms to derive meaningful answer from inconsistent ontology using paraconsistent logic.
