Scalable distributed information retrieval model based on topic map and mobil agent

In view of the problems of centralized search engine and based on analyzing the technology of topic map, OAI, mobile Agent and P2P, we design and implement a Scalable Distributed Retrieval Model based on Topic Map and Mobile Agent. The model can effectively improve the utilization rate of resources, increase search depth, overcome server failure and heterogeneity of network, and has a strong capacity for expansion, fault-tolerant and parallel processing
