Microblogging is a new form of communication in which users can describe their current status in short texts. We analyze these contents by two approaches -- positive vs. negative determination and sentiment analysis. Moreover, we use the multiple regression is order to get the semantic orientations which have an impact to investigation objects, and we also use chunking is order to extract topics that cause reputation changes. We evaluated our method by applying it to the politics and the ratings of TV dramas.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"電子情報通信学会"}]},"item_10001_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://search.ieice.org/index.html","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © 2011 IEICE"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1881-0225","subitem_source_identifier_type":"ISSN"}]},"item_10001_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":"橋本, 和幸","creatorNameLang":"ja"},{"creatorName":"ハシモト, カズユキ","creatorNameLang":"ja-Kana"},{"creatorName":"HASHIMOTO, Kazuyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中川, 博之","creatorNameLang":"ja"},{"creatorName":"ナカガワ, ヒロユキ","creatorNameLang":"ja-Kana"},{"creatorName":"NAKAGAWA, Hiroyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田原, 康之","creatorNameLang":"ja"},{"creatorName":"タハラ, ヤスユキ","creatorNameLang":"ja-Kana"},{"creatorName":"TAHARA, Yasuyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大須賀, 昭彦","creatorNameLang":"ja"},{"creatorName":"オオスガ, アキヒコ","creatorNameLang":"ja-Kana"},{"creatorName":"OHSUGA, Akihiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-05-08"}],"displaytype":"detail","filename":"j94-d_11_1762.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"j94-d_11_1762","url":"https://uec.repo.nii.ac.jp/record/9165/files/j94-d_11_1762.pdf"},"version_id":"aace1cd4-d032-4bc1-84dc-cf36050401d9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"マイクロブログ","subitem_subject_scheme":"Other"},{"subitem_subject":"評判抽出","subitem_subject_scheme":"Other"},{"subitem_subject":"センチメント分析","subitem_subject_scheme":"Other"},{"subitem_subject":"トピック抽出","subitem_subject_scheme":"Other"},{"subitem_subject":"Webエージェント","subitem_subject_scheme":"Other"},{"subitem_subject":"microblogging","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"reputation trend extraction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sentiment analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"topic extraction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Web agents","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"センチメント分析とトピック抽出によるマイクロブログからの評判傾向抽出","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"センチメント分析とトピック抽出によるマイクロブログからの評判傾向抽出","subitem_title_language":"ja"},{"subitem_title":"Reputation Trend Extraction from Microblogging Using Sentiment Analysis and Topic Extraction","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"13","path":["6"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2019-05-08"},"publish_date":"2019-05-08","publish_status":"0","recid":"9165","relation_version_is_last":true,"title":["センチメント分析とトピック抽出によるマイクロブログからの評判傾向抽出"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2024-03-01T07:41:27.018501+00:00"}
