Bayesian filter was used on existing learning spam filters which achieved some positive results. Although we expect them to improve the true negative rate while keeping the false positive rate low. Therefore, it was based on a thorough review of distribution for each word and mail that our means of spam mail detectionshowed an impressively higher accuracy than ever.","subitem_description_type":"Abstract"}]},"item_6_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_6_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"情報処理学会論文誌 数理モデル化と応用1(1): 175–184 (2008)","subitem_description_type":"Other"}]},"item_6_link_3":{"attribute_name":"信州大学研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"丸山, 稔","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.WCnCbpkh.html"}]},"item_6_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"一般社団法人情報処理学会"}]},"item_6_rights_62":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (c) 2008 by the Information Processing Society of Japan"}]},"item_6_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0387-5806","subitem_source_identifier_type":"ISSN"}]},"item_6_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11464803","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"丸山,  稔"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"谷岡,  広樹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中川,  尚"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"IPSJ-TOM0101015.pdf","filesize":[{"value":"553.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"IPSJ-TOM0101015.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/12493/files/IPSJ-TOM0101015.pdf"},"version_id":"a80035f4-e397-4f3a-b8fc-eefa44e9132f"}]},"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":"特徴抽出方法の改善によるベイジアンフィルタの精度向上","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"特徴抽出方法の改善によるベイジアンフィルタの精度向上","subitem_title_language":"ja"}]},"item_type_id":"6","owner":"1","path":["1222"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2011-03-10"},"publish_date":"2011-03-10","publish_status":"0","recid":"12493","relation_version_is_last":true,"title":["特徴抽出方法の改善によるベイジアンフィルタの精度向上"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-14T04:07:03.891862+00:00"}
