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.
