Content-awareness Communication Protocol Based On Ontology In Multi-agent System

With the continuous development of computer technology, network resources have become onerous, people demand more and more sharing of resources professional, how to find mass of information resources needed to become a serious problem. As network technology upgrading and development of the Semantic Web represents the next generation of network development and trends. Semantic Web will give more specific information resources, a more complete semantic information so that computers can understand the network resources, the realization of network data and handle the semantic Web services and intelligent, which will build a powerful network of existing, ubiquitous in information integration and exchange platform.In computer network, the rule used to prescribe the format of information and how to send and receive information is called network protocol or communication protocol. Knowledge communication is the communication built on top of existing networks of communication. Basic layer communication implement the share of computers and resource by and large, however, due to the lack of a unified network of content standards, this network of interaction between different areas, or resource sharing is not easy.Under this scene, knowledge communication is present; its essential is, establishing semantic inter-operation of information and knowledge in many information systems to implement across-the-aboard, realize network high layer communication with high efficiency.Agent technology by providing a wealth of information to guide the type and semantic knowledge of communication with the semantics of communication, its essence is a multi-Agent interaction, enhance the Agent's problem solving ability, to help other Agent will complete the problem solving and communication content accurate transmission enhance mutual understanding of communication. The knowledge, communication protocol applied to the Semantic Web services is to expect the Agent on the Semantic Web services can automatically discover, invoke and complex, so that people can search from the flood of information to get out.This article first intelligent agent (Agent), the contents of perception, ontology, and other basic concepts are introduced, followed by use of ontology to describe selected resources, the establishment of a new set of communication protocols and the corresponding communication ontology, and ontology mapping technology through research individuals with multiple communication (M-Agent) the ability to understand the content between. To use this knowledge to create a new communication protocol to strengthen the communication from the semantics of control, individuals can reach different areas of communications interoperability, to better improve communication quality. This article made the following three main areas:(1) Select the appropriate body and establish the similarity between ontology and heterogeneous ontology mapping, semantic content of communication to reach understanding, while the communications content check;(2) Redefined based on FIPA ACL Multi-Agent communication protocols, to communicate using the corresponding Multi-Agent ontology system;(3) defines a formal model of knowledge communication protocols, and the use of multi-Agent Based on this communication, the information added in the content layer, and the description of communication in the communication state control layer to ensure the communication quality, and effectively improve the quality of network communications.
