Description

It is difficult for developer of products to investigate which part and element of a product is closely related to its attraction and ease-of-use. So we propose a method which investigates what has an influence on facility and preference with a product by adopting C4.5, which is a useful algorithm for building decision tree. In this paper, we investigate what viewpoint a golf player values ease-ofhitting with golf clubs from. At first, we selected a lot of adjectives which are well used in the case that golf players evaluate a golf club from the viewpoint of how easily he is able to hit a golf ball with it. Next we investigated values of many golf clubs from the viewpoint of the adjectives by questionnaire and analyzed the correlation between the ease-of-hitting and the adjectives. As a result, we got some rules to judge the ease-of-hitting and preference with golf club.
