【摘要】 随着Internet技术及应用的发展,基于分布式的异质信息资源的信息检索成为当前学术领域中的一个研究热点。文章在分析了目前解决该相关领域问题的几种典型技术的基础上,结合电子政务平台上的实际应用需求,提出了一种基于LDAP(Lightweight Directory Access Protocol)和多Agent的分布式网络信息检索模型,并对其中的关键技术进行了深入的探讨,如基于多目录服务的元数据组织、多Agent间的通信,最后给出了基于J2EE平台的系统模型实现。更多还原

【Abstract】 With the development of Internet technology,the information retrieval based on distributed heterogeneous information resources becomes a focus of studying in the sphere of learning at present.After analyzing several typical technologies which are relevant to this studying field and according to the applied requirement of E-government platform,this paper proposes a distributed network information search model,which is based on lightweight directory access protocol(LDAP) and multi-agent technology.It also presents the key techniques,such as the information organization based on directory service technology and communication among multi-agent.Finally,it provides the systematic model based on J2EE platform to realize.更多还原
