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.
