を用いて参考文献文字列から書誌情報を自動抽出するが，その際，CRF で利用する素性が書誌情報の抽出精度を左右する．そこで実験により，使用する素性を変えて書誌情報の抽出精度を比較し，参考文献文字列のトークン化においては文字列素性と Bigram 素性が有効であり，トークンへの書誌要素ラベル付与においては辞書素性が有効であることを確認した．そして，本研究では書誌要素ラベル付与に有効であった辞書素性を拡充し，適当な素性を選択することによって抽出精度が向上することを確認した．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告データベースシステム（DBS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2015-11-19","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2015-DBS-162"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"updated":"2025-01-20T18:11:04.183032+00:00"}
