This requires lyrics emotion corpora of phrase. However, it is difficult to build large scale lyrics emotion corpora because emotions are labelled manually. In this paper, we propose a method to augment lyrics emotion corpora. As a result, we augmented a corpus consisting of 366 phrases into a larger corpus consisting of 2145 phrases. We also evaluate the proposed method using 2 convolutional neural networks trained on original corpus and augmented corpus respectively. We define the target emotion classes as Joy, Love, Anger, Sorrow and Anxiety. Mean accuracy of the model trained on the augmented corpus was 75.9% whilst the model trained on the original corpus performed 70.7%.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Academy of Sciences Malaysia","subitem_publisher_language":"en"}]},"item_10001_rights_15":{"attribute_name":"権利情報","attribute_value_mlt":[{"subitem_rights":"© Academy of Sciences Malaysia","subitem_rights_language":"en"}]},"item_10001_source_id_9":{"attribute_name":"収録物ID","attribute_value_mlt":[{"subitem_source_identifier":"18236782","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"26828901","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1715043197608":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access"}]},"item_1723180141928":{"attribute_name":"EID","attribute_value_mlt":[{"subitem_identifier_type":"URI","subitem_identifier_uri":"364214"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"カタオカ, アサキ","creatorNameLang":"ja"},{"creatorName":"カタオカ, アサキ","creatorNameLang":"ja-Kana"},{"creatorName":"Kataoka, Asaki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"ササヤマ, マナブ","creatorNameLang":"ja"},{"creatorName":"ササヤマ, マナブ","creatorNameLang":"ja-Kana"},{"creatorName":"Sasayama, Manabu","creatorNameLang":"en"}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":"","affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"http://www.isni.org/isni/"}],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"松本, 和幸","creatorNameLang":"ja"},{"creatorName":"マツモト, カズユキ","creatorNameLang":"ja-Kana"},{"creatorName":"Matsumoto, Kazuyuki","creatorNameLang":"en"}],"familyNames":[{"familyName":"松本","familyNameLang":"ja"},{"familyName":"マツモト","familyNameLang":"ja-Kana"},{"familyName":"Matsumoto","familyNameLang":"en"}],"givenNames":[{"givenName":"和幸","givenNameLang":"ja"},{"givenName":"カズユキ","givenNameLang":"ja-Kana"},{"givenName":"Kazuyuki","givenNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"311","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"174482/profile-ja.html","nameIdentifierScheme":"徳島大学 教育研究者総覧","nameIdentifierURI":"http://pub2.db.tokushima-u.ac.jp/ERD/person/174482/profile-ja.html"},{"nameIdentifier":"90509754","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/search/?qm=90509754"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2022-05-24"}],"displaytype":"detail","filename":"asmsj_13_S3_11.pdf","filesize":[{"value":"347 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://tokushima-u.repo.nii.ac.jp/record/2009348/files/asmsj_13_S3_11.pdf"},"version_id":"b44f3e83-bef9-4c34-b6d0-b5d2db23b884"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"lyrics emotion estimation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"text data augmentation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"word2vec","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"convolutional neural network","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Data Augmentation for Lyrics Emotion Estimation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Data Augmentation for Lyrics Emotion Estimation","subitem_title_language":"en"}]},"item_type_id":"40001","owner":"7","path":["1713853295607"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-05-24"},"publish_date":"2022-05-24","publish_status":"0","recid":"2009348","relation_version_is_last":true,"title":["Data Augmentation for Lyrics Emotion Estimation"],"weko_creator_id":"7","weko_shared_id":-1},"updated":"2025-01-27T07:19:47.577090+00:00"}
