On mutual understanding among communicating agents
Patrick Doherty, Witold Łukaszewicz, Andrzej Szałas · 2003
Abstract. In this paper, we propose a framework that provides software agents with the ability to ask approximate questions to each other in the context of heterogeneous ontologies. The framework combines the use of logic-based techniques with ideas from rough set theory. Initial queries by an agent are transformed into approximate queries using weakest sufficient and strongest necessary conditions on the query and are interpreted as lower and upper approximations on the query. Once the base communication ability is provided, the framework is extended to situations where there is not only a mismatch between agent ontologies, but the agents have varying ability to perceive their environments. These limitations on perceptive capability are formalized using the idea of tolerance spaces. 1
