Recently, many methods of opinion extraction from customer reviews in web pages were proposed. However, there are few work to retrieve objects which is the opinion target using these opinions with natural language query. Our system extract opinion tuples using syntactic structurual patterns which include modification relation between bunsetsus. And then, the system compares these opinion tuples and the tuples extraced from the user query, and ranks opinion objects using a tf ・ idf-like scoring formula. The precision rate of extracting relevance opinions by the system was 91.9%.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/8539"}]},"item_10_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会","subitem_publisher_language":"ja"}]},"item_10_relation_43":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://slp.el.itc.nagoya-u.ac.jp/paper_pdf/2006/NL2006_sugiki.pdf","subitem_relation_type_select":"URI"}}]},"item_10_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"ここに掲載した著作物の利用に関する注意 本著作物の著作権は（社）情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。","subitem_rights_language":"ja"},{"subitem_rights":"Notice for the use of this material The copyright of this material is retained by the Information Processing Society of Japan (IPSJ).
