Abstract:
In order to realize interoperability to a large number of autonomous and heterogeneous information sources with high efficiency, an agent-based multi-broker architecture(AMA)—HustEven, is constructed.A group of broker agents are designed to provide brokering services in a peer-to-peer(P2P)manner for the non-broker agents(user agents, resource agents, query agents).Thus, the scalability and robustness of the system are enhanced.Ontology is also used by the broker agents for facilitating interoperability among all the agents in HustEven.Unlike any other AMAs, an interdomain ontology is built in this system to represent the relationships among the common concepts in the innerdomain ontologies.Therefore, a broker forwards the queries only to the other related brokers according to the interdomain ontology and the communication overhead among the brokers is reduced.Obviously, the application of the interdomain ontology enables a broker to fully take advantage of the multi-broker architecture.The experimental results show that the HustEven performs more efficiently than any other existing systems.
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.
