Abstract : This thesis studies how a context-based approach could improve interoperability between heterogeneous ontologies developed and evolving autonomously. The hypothesis is that during collaborations, organizations exchange their data whose meaning is described by concepts defined by ontologies. The objective is to propose a context-based evaluation of such concepts.
We propose a methodology to determine, model and use the context. Applying this methodology, we uncover three usages of context that may be used together to improve ontology reconciliation: We propose to disambiguate among the possible pragmatic meanings of the concepts by comparing the “perspectives” with or for which the concepts have been developed; to personalize this comparison by considering the agent's context, made of a relevant selection of the agent's company domains and tasks; to evaluate the pertinence of the data associated with the concept for the task that triggered the interoperability need.
