事例ベース推論における事例の特徴付け機能, 選択機能, 修正機能の関係について

抄録

This paper describes an application of Case-Based Reasoning (CBR) system for a design problem of Nb-Ti superconducting wire. The developed system has two distinctive features : (1) Basic similarity degree between cases is derived using fuzzy matching. (2) Additionally, another similarity degree is defined considering the basic similarity degree and case modifying knowledge base. This similarity degree, which is named extended similarity degree, is the only criterion when selecting a past case similar to the given problem. Therefore, the case selecting function depends on the case modifying knowledge base. Moreover, it is shown that the case defining function is also effected by the case modifying knowledge base.
