Abstract
Semantical interpretation of the degrees of membership values is one of the fundamental issues in the theory of fuzzy sets. This study addresses such an issue in the light of the newly developed rough set theory. The connections between theories of fuzzy sets and rough sets are established, and the notion of interval fuzzy sets is studied. A salient feature of the rough set based interpretation of fuzzy sets is that the relationship between elements of the universe is considered. More specifically, the membership values of related elements are related in the proposed framework
