Abstract

In the paper, we introduce a new kind of fuzzy formal concept derived from an adjoint pair of operations. Based on the discussed fuzzy formal concepts, a pair of rough fuzzy set approximations in fuzzy formal contexts is introduced. The properties of the proposed approximation operators are examined in details.
