| Abstract(in English) | Currently, many information retrieval systems that combine multiple retrieval results have been proposed to improve the accuracy of these infomration retrieval systems. In these systems, selections of the combination functions, the functions for combining multiple relevance scores, are important to improve the accuracies. We seem that the most suitable combination function should change by the users' queries. In this paper, we propose an automatic selection method of combination functions. In our method, we automatically select using the distributions of relevance scores. When a retrieval system calculates a small number of high relevance scores, the system can identify relevant retrieval targets. Therefore, we suppose that the sureness of the combination functions should depends on the number of high relevance scores. Then, we propose a calculating method of the sureness of combination function using Shannon's information measure. From our experimental results, we find out that our proposed method can select better combination functions. |
