JavaScript を埋め込んで取得した情報を利用し，教師なし機械学習を用いた手法で問題行為検知を行った．そして，問題行為をしたと判定された受験者に聞き取り調査を行った．その後，問題行為に共通した挙動を特定するため，ランダムフォレストを用いて問題行為検知に重要な特徴量の特定を行った．その結果，問題をフォーカスした時間と問題行為検知との間に相関があることが判明した．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告コンピュータセキュリティ（CSEC）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2021-11-01","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"28","bibliographicVolumeNumber":"2021-CSEC-95"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":213659,"updated":"2025-01-19T17:04:42.333699+00:00","links":{},"created":"2025-01-19T01:14:30.837623+00:00"}
