Abstract
The paper studies the axiomatization of rough sets with a new approach, that is, the matroidal approach. First, Pawlak matroids are introduced. Properties of Pawlak matroids are studied. Then three sets of axioms of the Pawlak upper approximation operator are proposed from a matroidal point of view. Additionally, a possible generalization of Pawlak rough sets based on coverings is pointed out.
