- 出版タイプ： VoRtype:text[あらまし] 協調フィルタリングを用いたユーザベースの授業推薦システムのプロトタイプを作成し評価を行なったところ,網羅性,精確性の改善,ユーザインタフェースの改善,時間割による制限への対応が必要であることがわかった.それに対応するため,アイテムベースの推薦を追加し類似度の計算尺度の改善を行なった.また,自分と類似した先輩の履修授業を推薦する先輩推薦と,時間割を考慮した協調推薦の機能を設けた.さらにアイテムベースの相関推薦も併用することで学生の主体性の維持を図った.推薦画面を時間割ベースに変更した.この評価の結果,この改良版プロトタイプは,網羅性と精確性を備えていること,高い主体性の維持が確認できた.[Abstract] The Lecture Recommendation System based on User-Based Collaborative Filtering had been completed. The improvement of comprehensiveness, precision and user interface would be needed. In order to improve the system, Item-based Collaborative Filtering and Cosine Similarity were introduced. The Senior Recommendation could recommend lectures the seniors who are similar to the user registered. The Collaboration Recommendation based on User-Based Collaborative Filtering and the Item Recommendation based on Item-Based Item-to-item Collaborative Filtering had been developed to improve the initiative of students. In evaluation of the improved prototype with the form of a timetable, it is confirmed that the system performance was increased.
