Inclusion Degree Theory among Concepts of Formal Concept Analysis
形式概念分析的概念之间包含度理论

Inclusion degree theory was introduced into the concepts of formal concept analysis.In this theory,quantitative relation among concepts was described and the sub-concept and super-concept in concept lattice was depicted.Meanwhile,by using inclusion degree association rules were extracted from the concept lattice,and an algorithm of extracting non-redundant association rules was presented.Finally,an example was given to show that the algorithm is e-ffective.
