Construction of Three Attribute Oriented Concept Lattices

Based on the definitions of three attribute oriented concept lattices induced by attributes, the relationship among attribute induced three attribute oriented concept lattices, maximum concept set and minimum concept set was deduced, and a construction algorithm of attribute induced three attribute oriented concept lattices was proposed. The time complexities of general object-oriented concept lattice construction algorithm and the algorithm in this paper were compared and analyzed.The results show that the time efficiency of this algorithm is higher than that of general object-oriented concept lattice construction algorithm.
