Mapping Adaptation Actions for the Automatic Reconciliation of Dynamic Ontologies
Résumé
The highly dynamic nature of domain ontologies has a direct impact on semantic mappings established between concepts from different ontologies. Mappings must therefore be main- tained according to ongoing ontology changes. Since many software applications exploit mappings for managing infor- mation and knowledge, it is important to de ne appropriate adaptation strategies to apply to existing mappings in order to keep their validity over time. In this article, we propose a set of mapping adaptation actions and present how they are used to maintain mappings up-to-date based on ontol- ogy change operations of different nature. We conduct an experimental evaluation using life sciences ontologies and mappings. We measure the evolution of mappings based on the proposed approach to mapping adaptation. The re- sults con rm that mappings must be individually adapted according to the different types of ontology change.
