The Study And Application Of Agent Communication Technology Based-on Ontology In MAS

When we achieve system goals or solve a large-scale problem using autonomous and interactive of Agent in MAS, Agent communication is an important means to achieve interaction of Agents. However, the difference of knowledge and platform in each Agent, and the difference of the message involved in the concept, structure and message format led directly to poor communication between Agents. So need to share knowledge and unified message format between the various Agents. For this problem, the introduction of ontology to the Agent Communication is an effective method. As a knowledge representation method, ontology theory used to standardized ACL's content is a practical way. This can enhance the understanding of each other's intentions of Agent communication and effectively improve the efficiency of Agent Communication.To begin with, this paper depth study the existing results, detail the current Agent communication mechanism and ACL, studies the application of ontology and it's application in Agent communication. Moreover, based on analysis of ontology modeling and the basic functions of travel information, this paper definite the concepts and attributes and relationships of communication ontology used by the tourism system. According to FIPA standard, this paper design and implement a travel information service ontology-based MAS on JADE Agent platform. Communication message mechanism use FIPA ACL in regulating the message format and type, describe the contents of the message content by use of OWL. System implementation shows that the system can further ensure the consistency and completeness of knowledge of the tourism field, and effectively implement the semantic query information and intelligence service.
