Design and implementation of P2P based personalized Web search system
Ming Zhong · Computer Engineering and Applications Journal · 2007
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 proposes a P2P based Web search system called PeerBridge for personalized Web information searching.PeerBridge adopts the Distributed Hash Table(DHT) to organize a large number of network nodes to form a structured P2P overlay networks.Each peer acts as a topic driven search engine,which can seek useful information according to user's interests.Furthermore,those peers that have similar topics are associated together to form peer clusters.Peers cooperate to search the Web and share information.Some techniques such as topic driven Web crawling,semantic concept based document classification,personalized linkage analysis,and topic segment based P2P searching are used to improve the PeerBridge's performance.
