Then, we extracted a number of candidates of paraphrases of the final part of sentences from them automatically. At first we have aligned these two types of corpus first at article level, then at sentence level. Next, we extract the final part of mobile article sentences using morphological analyzer, and collect their counterpart expressions of Web article sentences. Finally, we extracted the candidates of morpheme sequence from the final part of Web article sentence, then we propose the combination of two methods for them in order to improve the extraction accuracy of the sets: 1) ranking based on frequency, branching factor and length of string, and 2) filtering to remove inappropriate expressions which eliminate semantically indispensable nouns.","subitem_description_type":"Abstract"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"106368","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Iwakoshi, Moritaka"}]},{"nameIdentifiers":[{"nameIdentifier":"106369","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Masuda, Hidetaka"}]},{"nameIdentifiers":[{"nameIdentifier":"106370","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nakagawa, Hiroshi"}]}]},"item_2_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"言語処理学会"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10472659","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13407619","subitem_source_identifier_type":"ISSN"}]},"item_2_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"007","subitem_subject_scheme":"NDC"}]},"item_2_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Association for Natural Language Processing"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京電機大学工学部"},{"subitem_text_value":"東京大学情報基盤センター"},{"subitem_text_value":"School of Engineering, Tokyo Denki University"},{"subitem_text_value":"Information Technology Center,The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"岩越, 守孝"}],"nameIdentifiers":[{"nameIdentifier":"106365","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"増田, 英孝"}],"nameIdentifiers":[{"nameIdentifier":"106366","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中川, 裕志"}],"nameIdentifiers":[{"nameIdentifier":"106367","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-26"}],"displaytype":"detail","filename":"v12n5_07.pdf","filesize":[{"value":"302.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"v12n5_07.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/419/files/v12n5_07.pdf"},"version_id":"415669e9-34e6-4fa0-9538-51b0fac6efec"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"言い換え","subitem_subject_scheme":"Other"},{"subitem_subject":"携帯端末","subitem_subject_scheme":"Other"},{"subitem_subject":"Web","subitem_subject_scheme":"Other"},{"subitem_subject":"文末表現","subitem_subject_scheme":"Other"},{"subitem_subject":"Paraphrase","subitem_subject_scheme":"Other"},{"subitem_subject":"Mobile terminal","subitem_subject_scheme":"Other"},{"subitem_subject":"Web","subitem_subject_scheme":"Other"},{"subitem_subject":"Sentence final part","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Webと携帯端末向けの新聞記事の対応コーパスからの文末言い換え抽出","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Webと携帯端末向けの新聞記事の対応コーパスからの文末言い換え抽出"}]},"item_type_id":"2","owner":"1","path":["13","15"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-12-15"},"publish_date":"2009-12-15","publish_status":"0","recid":"419","relation_version_is_last":true,"title":["Webと携帯端末向けの新聞記事の対応コーパスからの文末言い換え抽出"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:41:18.570939+00:00"}
