Dealing with?Missing Values Meaning Unknown in?Probabilistic Approximationse two possibilities, we handle missing values in probabilistic approximations by using possible world semantics, as it is used by Lipski in incomplete databases. As a result, we obtain the lower and the upper bound of the actual probabilistic approximation. We can obtain these bounds without worrying about the number of possible tables.

On Tolerance-Based Rough Set Operators and?Their Covering Generalizations on the nature of granules. We recall from literature some rough sets approximation operators: classical equivalential rough sets operators by Z.?Pawlak and their generalizations for tolerance relations: tolerance approximation operators by A.?Skowron and J.?Stepaniuk and tolerance-granular approxim
