Algorithm design of information retrieval based on P2P community

WANG Xin-hui Technological Information Department,Beijing Vocational College of Agriculture,Beijing 102442,China  
In order to effectively locate resourse and search information in P2P community,a hybrid P2P topology is adopted and the document searching in P2P community is divided into three processes:local retrieval,intra-search and inter-search.In local retrieval,the new term weight calculation method is designed to solve the problem about txt search in homogeneous collection.In intra-search and inter-search,a part of peers which are more relevant to the query to conduct the retrieval task is selected.Experimental results show that this method can get better retrieval results with lower cost.
