为了在集成大量异构自治信息资源时实现高效率互操作性,设计了一种基于智能体(agent)的多代理结构.用一组代理智能体以peer-to-peer(P2P)方式为其他非代理智能体提供代理服务,从而提高系统的可扩展性与健壮性.代理服务使用本体技术来实现系统互操作性.与其他多代理结构不同的是,除了领域内本体,还引入了一个领域间本体来表达各个领域内本体中公共概念的联系.因此,代理可以根据领域间本体的信息,将查询请求仅发往相关的代理,减少了网络通信量,更好地发挥多代理体系结构的优势.实验结果表明,系统实现互操作性的效率相对于现有的系统有明显的提高.
In order to achieve high efficiency interoperability when integrating a large number of heterogeneous autonomous information resources, an agent-based multi-agent structure is designed.With a set of agent agents peer-to-peer (P2P) Non-agent agents provide agency services to improve the scalability and robustness of the system.Agent services use ontology technology to achieve system interoperability.In contrast to other multi-agent architectures, in addition to the domain ontology, it also introduces a field Between the ontology to express the public concept of the connection in the ontology in various fields.Therefore, the agent can send the query request to the relevant agent according to the information of the interdomain ontology, reduce the network traffic, and give full play to the multi-agent architecture The experimental results show that the efficiency of system interoperability is obviously improved compared with the existing systems.
