Modeling Distribution and Exchange of Domain Knowledge in Multi-agent Environment

Abstract

Multi-agent systems often dedicate a shared centralized ontology as domain knowledge but unfortunately they completely neglect the decentralized nature of domain knowledge. This nature implies distributing domain knowledge on domain’s agents rather than centralize it in a shared ontology. This paper comes to embrace the trend of decentralizing domain knowledge by proposing the knowledge distribution model. Furthermore, the paper also proposes a knowledge exchange model in which a protocol and two types of queries are designed and implemented for exchange knowledge between agents. Different situations are presented to address the problem and the proposed model gives positive results in manipulating with all of these situations. Distributing knowledge, especially on autonomous agents, solves many problems of keeping and maintaining knowledge in one place which is a bottle neck of knowledge management.
