ZHANG Gang1,2,ZHOU Zhaotao1,2,WANG Bin1(1.Software Division,Institute of Computing Technology,Chinese Academy of Sciences,Beijing 100080;2.Graduate School of Chinese Academy of Sciences,Beijing 100039)  
This paper introduces a topic based distributed information retrieval method,thoroughly analyses the reason for the good performance.Through text clustering method,divides the text by theme,and the experimental results show that inquired answers obviously converge among minority collections of documents,such indicates that the topic based distributed information retrieval method achieves great improvement comparing to the traditional method.
