A RFCA-based Approach for Concept Similarity Computation
基于RFCA的概念相似度计算方法

In order to solve the problem the FCA-based concept similarity computational model can't compute similarity of two informal concepts,rough set theory is then introduced,the definition of equivalence relation of concept lattice is given,a novel similarity measure method based on rough set and formal concept analysis(RFCA) is proposed.The example proves the method is feasible.
