Standard との比較による正解率の各指標について，平均値とどちらか一方でも正解のタグを付与しているならば正解とみなした場合の数値を算出した．本実験の結果から，全体的に見たとき，既存のアノテーション結果を用いた手法は，アノテーションにかかる時間が少なく，一致率や正解率についても高い値になることがわかった．しかし，訓練事例から離れたジャンルのテキストについては，既存の固有表現抽出器を用いない手法の方が良い結果を出しており，このようなテキストについては，既存の固有表現抽出器を用いず，人手のみでアノテーションを行った方が良いと考えられる．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告自然言語処理（NL）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2016-09-22","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"7","bibliographicVolumeNumber":"2016-NL-228"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":174765,"created":"2025-01-19T00:44:52.561865+00:00"}
