フォークソノミに基づく教材データベースシステムの設計

摘要

初等から中等教育の教員は、3時間の授業に対し1時間の準備時間しか確保できず、非常に負担が大きい［1］。本論文では、教員の授業計画と教材準備を支援する教材データベースを設計する。教材の付加情報こ利用者の主観に基づいた「タグ」を付け加えることで、利用者に解りやすい教材の分類を実現する。また、「タグ」と「教材」の関係から、タグの親子関係と同値関係を導き出しタグの木構造を計算する。タグの木構造を検索に利用することによって、利用者のあいまいな検索を明確にする。%It is possible to secure for the class of three hours only at the setup time of one hour, and the teacher's of secondary education load is very large from primary. In this thesis, the teaching material data base that supports the teacher's syllabus and teaching material preparation is designed. The classification of a comprehensible teaching material is achieved in the user by adding "Tag" based on user's subjectivity to addition information on the teaching material. Moreover, a relationship between a child and his parents and an equivalent relation of tag are calculated from the relation between "Tag" and "Teaching material" and the tree structure of the deriving tag is calculated. The user's vague retrieval is clarified by using the tree structure of tag for the retrieval.
