Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a reputation information retrieval support system which displays detailed reputation information. From the keywords that user inputs, this system displays reputation information and its polarity (positive or negative) of each attribute. First, polar sentence dictionary of each attribute are created by learning relationship between a review and its score. Next, reputation information is classified into attribute categories and the polarity of reputation information is decided (P/N classification) by using the dictionary. Finally, Web browser displays reputation information of each attribute. Experimental results show that the accuracy of attribute classification is 79.9%, the P/N classification in P documents is 89.4%, and the P/N classification in N documents is 65.6%.
