The Use of the Belief Revision Concept to Ontology Revision
نویسندگان
چکیده
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.

Ontology Revision Through Concept Contraction
Belief revision deals with the question how to integrate conflicting information into a knowledge base. Classical belief revision thereby presumes that the information has a single interpretation. In relaxing this presumption — as usually done in the field of semantic integration — it is investigated how to handle the problem of integrating information α into an ontology O, if the (multiple) in...
متن کاملModel-based Revision Operators for Terminologies in Description Logics
The problem of revising an ontology consistently is closely related to the problem of belief revision which has been widely discussed in the literature. Some syntax-based belief revision operators have been adapted to revise ontologies in Description Logics (DLs). However, these operators remove the whole axioms to resolve logical contradictions and thus are not fine-grained. In this paper, we ...

متن کاملTableau-based revision in SHIQ
Introduction The problem of revising a description logic-based ontology (called DL ontology) is closely related to the problem of belief revision which has been widely discussed in the literature. Among early works on belief revision, the AGM theory (Alchourrón et al., 1985) introduced intuitive and plausible constraints (namely AGM postulates) which should be satisfied by any rational belief r...
متن کاملOntology Revision
Knowledge systems as currently configured are static in their concept sets. As knowledge maintenance becomes more sophisticated, the need to address issues concerning dynamic concept sets will naturally arise. Such dynamics is properly called ontology revision, or in the simpler case, expansion. A number of sub-disciplines in artificial intelligence, philosophy and recursion theory have results...
