Query-Space Based Collection Partition for Distributed Information Retrieval
Xueqi Cheng · Zhongwen xinxi xuebao · 2008
Proper collection partition can improve the performance of distributed information retrieval greatly.In order to solve the collection partition problem in distributed information retrieval,a query-space based collection partition algorithm was proposed in this paper.Comparing to the traditional document-space based partition algorithm,this algorithm was a new understanding and view point to collection partition.It gave a good solution for large scale document collection partition.The experiment indicates that this algorithm achieve great improvement in both effectiveness and efficiency.
