This system is targeted at users of personal computers. We released the system on the WWW in April 2002. In real world QA systems, vagueness of questions is a big problem. Our system can navigate users to the desired answers using the following methods: asking users back with dialog cards, and description extraction of each retrieved text. Another feature of the system is that it retrieves relevant texts precisely, using question types, synonymous expression dictionary, and modifier-head relations in Japanese sentences.","subitem_description_type":"Abstract"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"106310","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kiyota, Yoji"}]},{"nameIdentifiers":[{"nameIdentifier":"106311","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kurohashi, Sadaoand"}]},{"nameIdentifiers":[{"nameIdentifier":"106312","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kido, Fuyuko"}]}]},"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":"東京大学大学院情報理工学系研究科"},{"subitem_text_value":"科学技術振興事業団 さきがけ研究 21"},{"subitem_text_value":"マイクロソフト株式会社"},{"subitem_text_value":"Graduate School of Information Science and Technology, The University of Tokyo"},{"subitem_text_value":"PRESTO, JST"},{"subitem_text_value":"Microsoft Co., Ltd."}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"清田, 陽司"}],"nameIdentifiers":[{"nameIdentifier":"106307","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"黒橋, 禎夫"}],"nameIdentifiers":[{"nameIdentifier":"106308","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"木戸, 冬子"}],"nameIdentifiers":[{"nameIdentifier":"106309","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":"v10n4_08.pdf","filesize":[{"value":"330.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"v10n4_08.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/407/files/v10n4_08.pdf"},"version_id":"2984f48a-bdeb-46b4-bdf9-248b7ae1a353"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"対話システム","subitem_subject_scheme":"Other"},{"subitem_subject":"情報検索","subitem_subject_scheme":"Other"},{"subitem_subject":"質問応答","subitem_subject_scheme":"Other"},{"subitem_subject":"テキスト知識ベース","subitem_subject_scheme":"Other"},{"subitem_subject":"Dialogue System","subitem_subject_scheme":"Other"},{"subitem_subject":"Information Retrieval","subitem_subject_scheme":"Other"},{"subitem_subject":"Question Answering","subitem_subject_scheme":"Other"},{"subitem_subject":"Text Knowledge Base","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":"大規模テキスト知識ベースに基づく自動質問応答 : ダイアログナビ","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"大規模テキスト知識ベースに基づく自動質問応答 : ダイアログナビ"}]},"item_type_id":"2","owner":"1","path":["13","15"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-12-08"},"publish_date":"2009-12-08","publish_status":"0","recid":"407","relation_version_is_last":true,"title":["大規模テキスト知識ベースに基づく自動質問応答 : ダイアログナビ"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:41:14.576995+00:00"}
