Abstract
The purpose of this paper is to study the axiomatic approaches of rough set approximation operators in fuzzy formal contexts. We first define four types of fuzzy conceptual knowledge system, and then the axiomatic characterization for rough approximations operators is presented. The axioms that must be satisfied by the operators are stated.
