摘　　要：本文提出一种基于代理的语义对等网环境下数字图书馆的四层模型,包括资源层、对等层、代理层和应用层,分述了各层的功能,探讨了各代理采用工作流模式实现网络服务的过程。异构数字资源的对等连接能够保证系统搜索的实时性和深度,本体的引入可以增强语义,代理的应用则加强了系统的自主性和适应性。仿真实验表明模型是有效的。A model consisting of 4 layers,i.e.resources layer,P2P layer,agent layer and application layer for digital library based on agents in the semantic P2P environment is presented and the function of each layer is elaborated.The process of each agent to provide Web service by the use of the workflow model is also explored.The P2P connection of the heterogeneous digital resources can ensure the real time and depth of the system search,the introduction of the ontology can enhance the semantics,and the application of the agents can enhance the autonomy and adaptability of the system.The simulation experiment shows that the model is valid.
