ABSTRACT

The appropriateness measure of label expression is a basal concept in uncertainty modelling based on label semantics theory for dealing with vague concepts. In the paper, the concept of disjunctive normal forms is presented. It is proved that each label expression is semantic equivalent to a disjunctive normal form. Further, a new method of calculating the appropriateness measures of label expressions is provided.
