Description: The article discusses a number of issues related to the inductive generalization of concepts in intelligent and expert systems. We studied logical approach to the definition of attributes list on which we can construct a generalization. To investigate the distinctiveness function, the matrix section and legibility. An example illustrating the method used and its advantages.
Keywords: rough sets theory, generalization of concepts, expert system, information system, attitude indistinguishable space approximations, approximation space, equivalence, the lower approximation of the set upper approximation for the set, a generalized solution
