Abstract
Interaction among agents about reputation is essential to accelerate the convergence of the reputation evaluation. Semantic heterogeneity of different reputation models makes agent interaction a problem, especially in open MAS. We propose in this paper a service oriented architecture, SOARI , to deal with this problem. Namely, SOARI is composed of an external Ontology Mapping Service ( OMS ) and an agent internal Translator module. This architecture supports concept mapping and translation among reputation model ontologies to a common ontology and vice-versa, thus allowing heterogeneous agents to interoperate about reputation. We present an example of the OMS 's use, by showing the mapping of two reputation models to a common ontology. Finally, we illustrate the use of the whole SOARI architecture in a simplified electronic commerce scenario. These experiments have enabled us to analyze the limitations and advantages of a hybrid approach for heterogeneous agents interoperation.
