Interactive ontology evolution management using mutli-agent system A proposal for sustainability of semantic interoperability in SOA

this paper discusses a new approach towards ontology evolution management framework and relates it to the sustainability of semantic interoperability in SOA. Indeed, when the semantic representation of the service evolves, the interpretation of queries may change. Thus, it's often challenging to evaluate the results of the query. Sources of this problem include the lack of support for semantic evolution management in ontology-based service oriented systems, and the static nature of the mappings between ontologies in this environment. To address these issues, we have developed P(2)OManager, an interactive tool for ontology evolution management. This system allows the users to automatically create an ontology agent manager. This agent manages evolution on both ontology and mappings and communicates with other ontology agents to take them aware of all changes which may affect exchanges with their services. Examples illustrate how P(2)OManager can provide valuable support for ontology evolution management, when specific changes are provided.
