A User-driven and a Semantic-based Ontology Mapping Evolution Approach

Systems or software agents do not always agree on the information being shared, justifying the use of distinct ontologies for the same domain. For achieving interoperability, declarative mappings are used as a basis for exchanging information between systems. However, in dynamic environments like the Web and the Semantic Web, ontologies constantly evolve, potentially leading to invalid ontology mappings. This paper presents two approaches for managing ontology mapping evolution: a user-centric approach in which the user defines the mapping evolution strategies to be applied automatically by the system, and a semanticbased approach, in which the ontology’s evolution logs are exploited to capture the semantics of changes and then adapted to (and applied on at) the ontology mapping evolution process.
