Parallel Query and Ranking Mechanism in Super-peers Network
Bin Li · Jisuanji gongcheng · 2010
Super peers in super-peers network may become the network performance bottleneck and affect retrieval result global ranking. Aiming at this problem,this paper presents a parallel query and ranking mechanism. A building method for indexes such as class feature and a selection algorithm for query peers are presented to decrease the storage and computation burden of super peers and make it connect more common peers as possible in the scope of load capacity. A query and ranking method of query peers is presented to improve retrieval quality. Experimental results show that the mechanism is efficient.
