In this note, we show some improvements for Theorem 7 and Example 8 inShiping Wang[Information Sciences 263(1), 186-197, 2014]. Concretely, we studyfurther the sixth lower and upper approximations of sets for coveringapproximation spaces. Furthermore, we present the sixth dual lower and upperapproximations of sets for covering approximation spaces. We also construct thesixth dual lower and upper approximations of sets from the view of matrix.Throughout, we use the same notations as Shiping Wang[Information Sciences263(1), 186-197, 2014].
