Abstract: To overcome some disadvantages of the centralized search engines such as not facilitating human user collaboration, ignoring completely the interests and preferences of users, not being scalable and timely, this paper proposed a P2P based Web search system called PeerBridge for personalized Web information searching. PeerBride adopted the distributed hash table (DHT) to organize a large number of network nodes to form a structured P2P overlay networks. Each peer acted as a topic driven search engine, which can seek useful information according user’s interests. Furthermore, those peers that have similar topics were associated together to form peer clusters. Peers cooperated to search the Web and share information. Some technique such as topic driven Web crawling, semantic concept based document classification, personalized linkage analysis, and topic segment based P2P searching were used to improve the PeerBridge’s performance.
