A neural network was used to analyze the determinants of the decision structure of ranking in Moody's Investors Service and Standard & Poor's Corp. of the United States or the ranking research institute and the rating and investment information center of Japan, aiming to elucidate the decision structure of ranking, and was also used to analyze the manufacturing industry. These analyses provided highly accurate information that was found to be much more accurate than the information obtained with the existing analysis method. However, the characteristics of this information in the finance business have not been clarified yet. I would like to continue to research financial institutions using this method in the future.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究（C）;  研究期間：2008～2010;   課題番号：20530289;   研究分野：社会科学;   科研費の分科・細目：財政学・金融論","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/r/70434850"}]},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/r/20155120"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"},{"subitem_text_value":"連携研究者"},{"subitem_text_value":"連携研究者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"KATSUDA, HIDEKI"},{"subitem_text_language":"en","subitem_text_value":"TANAKA, KATSUAKI"},{"subitem_text_language":"en","subitem_text_value":"HAGIWARA, MOTOHIRO"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学経営学部; 教授"},{"subitem_text_value":"摂南大学経営情報学部; 教授"},{"subitem_text_value":"明治大学商学部; 教授"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"勝田,  英紀"},{"creatorName":"カツダ, ヒデキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3454","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"40314348","nameIdentifierScheme":"研究者番号","nameIdentifierURI":" "}]},{"creatorNames":[{"creatorName":"田中,  克明"},{"creatorName":"タナカ, カツアキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3455","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"萩原,  統宏"},{"creatorName":"ハギワラ, モトヒロ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3456","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":"2016-02-17"}],"displaytype":"detail","filename":"KAKEN_20530289seika.pdf","filesize":[{"value":"170.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KAKEN_20530289seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/3127/files/KAKEN_20530289seika.pdf"},"version_id":"4ae4f229-1f6c-4f03-a628-191f7263d3f0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ファイナンス","subitem_subject_scheme":"Other"},{"subitem_subject":"ニューラル・ネットワーク","subitem_subject_scheme":"Other"},{"subitem_subject":"格付","subitem_subject_scheme":"Other"},{"subitem_subject":"決定構造","subitem_subject_scheme":"Other"},{"subitem_subject":"定量分析","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"ニューラル・ネットワークを用いた企業格付の定量分析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ニューラル・ネットワークを用いた企業格付の定量分析"}]},"item_type_id":"8","owner":"3","path":["2693","2694"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-07-08"},"publish_date":"2011-07-08","publish_status":"0","recid":"3127","relation_version_is_last":true,"title":["ニューラル・ネットワークを用いた企業格付の定量分析"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-21T01:45:47.806613+00:00"}
