The concept of fuzzy approximation space that depends on a fuzzy proximity relation is a generalization of the concept of the knowledge base. But intuitionistic fuzzy approximation space that depends on an intuitionistic fuzzy proximity relation is a better generalization of the concept of knowledge base than fuzzy approximation space. Therefore, rough sets defined on intuitionistic fuzzy approximation spaces extend the concept of rough sets on fuzzy approximation spaces. This paper presents how rough sets on intuitionistic fuzzy approximation spaces provides better result over rough sets on fuzzy approximation spaces on knowledge representation.
