Abstract(in English) In order to achieve faceted search in net auction system, several researchers have dealt with the automated extraction of attributes and their values from descriptions of exhibits. In this paper, we studied a method to improve the performance of the extraction. First, the method selects each sentence in a description that is judged to have attributes and/or values. Then, the extraction of attributes and values are performed on the cleaned text that does not contain parts of description irrelevant to exhibits, like descriptions for the postage, other exhibits, and so on. The experimental result shows that the proposed method improves both the precision and the recall in the attribute-value extraction.
