Achieving Accords over Agents Own Ontology

摘要

A method for building possible correspondences between the ontologies of two communicating agents is presented, without the need of complete disclosure oftheir ontologies. The central element of our approach is an abductive argumentative framework allowing to decide the needed and sufficient knowledge to make a decision in the current context and current goal, assuming the existence of a preference relation on rules governing the decision process. The negotiated accords are focusing on the concept that raised the problem, involved agents exchanging the knowledge related to it. Two different sides of the decision process can be identified: minimal sufficient extention of agent''s knowledge about other participants'' knowledge and reaching the mutual acceptable proposal based on negotiation.
