摘要
In this paper, we introduce a criterion of similarity between partitions. The proposed similarity criterion is a generalization of an evaluation criterion of relative reducts proposed by the authors and evaluates the similarity of partitions by correctness and roughness with each other. Moreover, for comparison of similarity scores between different universes, we also propose a normalized similarity criterion.
