Abstract:Fuzzy class can be obtained via fuzzy relevance degrees approach. The relationships among the attributes can be described by fuzzy rules enclosed in the fuzzy class. And the membership functions, which are used to calculate the membership degree of subclass and super-class, and the membership degree of object and class, are defined according to fuzzy relevance degrees and fuzzy range. Thereby, the problem of imprecise and uncertain information acquirement can be settled. As a result, this approach can be applied to modeling the imprecise requirement.
Keywords:fuzzy relevance degrees   fuzzy class   imprecise requirement
