We study the changing role of WOM communications using data on Japanese serial dramas between 2017 and 2018. Our goals are two folds. First, we document how the valence and contents of WOM change over time through topic modeling and sentiment analysis. Second, we develop a structural Bayesian learning model of consumers’ drama viewing decisions and evaluate how informational and consumption values of WOM communications vary over time, by topic and sentiment. We find that WOM on experiential attributes of dramas and neutral and negative WOM contents have higher informational values than other WOM contents. Moreover, WOM on negative emotions and drama’s storyline tend to generate higher consumption values. Our results provide insights into how to design products and services effectively so as to benefit from the changing roles of WOM communications.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"企業研究所","subitem_publisher_language":"ja"}]},"item_10002_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"この資料の著作権は、資料の著作者または学校法人中央大学に帰属します。著作権法が定める私的利用・引用を超える使用を希望される場合には、掲載誌発行部局へお問い合わせください。","subitem_rights_language":"ja"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1347-9938","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","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":"石原,昌和","creatorNameLang":"ja"},{"creatorName":"イシハラ,マサカズ"},{"creatorName":"ISHIHARA,Masakazu"}]},{"creatorNames":[{"creatorName":"熊倉,広志","creatorNameLang":"ja"},{"creatorName":"クマクラ,ヒロシ"},{"creatorName":"KUMAKURA,Hiroshi"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","fileDate":[{"fileDateType":"Issued"}],"filename":"1347-9938-42-04.pdf","mimetype":"application/pdf","url":{"url":"https://chuo-u.repo.nii.ac.jp/record/2000130/files/1347-9938-42-04.pdf"},"version_id":"eec44067-0b4c-4eeb-bc1c-c660e65a37cb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Word-of-Mouth ","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":" Topic Modeling ","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":" Sentiment Analysis ","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":" Bayesian Learning ","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":" Structural Estimation","subitem_subject_language":"en","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"連続TVドラマにおけるクチコミの情報価値と消費価値","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"連続TVドラマにおけるクチコミの情報価値と消費価値","subitem_title_language":"ja"},{"subitem_title":"Informational and Consumption Values of Word-of-Mouth Communications in Serial Drama Viewing : An Empirical Investigation","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"8","path":["1694589335845"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-09-13"},"publish_date":"2023-09-13","publish_status":"0","recid":"2000130","relation_version_is_last":true,"title":["連続TVドラマにおけるクチコミの情報価値と消費価値"],"weko_creator_id":"8","weko_shared_id":-1},"updated":"2023-09-14T04:29:58.449653+00:00"}
