Exploiting interaction contexts for dynamic ontology mapping

Paolo Besana

In this SSP talk I will present my thesis proposal. This proposal addresses the problem of ontology heterogeneity in open multi-agent systems.  In open MAS, it is often an impossible requirement that all agents share an ontology or that all the combination of mappings between different ontologies are foreseen.  My proposal starts from the pragmatic assumption that understanding between agents is needed only to perform the interactions required for reaching some common goal. I propose that only small portions of ontologies, relevant to the context of the interactions are mapped. The mapping framework  exploits the experience gained in previous interactions to quickly classify the dialogue into a context and then uses the context to filter out the unrelated parts of the ontologies. The mapping itself is modelled as decision-making under uncertainty.
