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.
