Search Model, Based On Ldap And Distributed Network Of Multi-agent

With the popularity of networking technology and rapid development of electronic commerce, all kinds of network services have become quite indispensable to people's daily lives and workings. Meanwhile, the requirement of network services has increased more and more in the society because network application has been wildly and deeply used. People require not only the limited network services provided by local departments or districts, but also information resources sharing over different departments or vocations or even as large areas as possible. This thesis sets the construction of Fujian e-government platform as a background, deeply studies and discusses the problem that how to access the information sources which are spread in different areas and heterogeneous in content by the e-government platform. After analyzing several typical technologies that are relevant to this studying field and according to the character of this studying background, this thesis proposes a distributed network information search model, which is based on lightweight directory access protocol (LDAP) and multi-agent technology. In this model, the efficiency of information access is greatly improved by using directory service technology and the problem that how to share heterogeneous information resources is solved effectively by using multi-agent technology and XML technology together. Finally, this thesis designs an implement framework by using J2EE platform and makes an example to verify the feasibility of this implement framework.
