Abstract To meet user′s requirements of the interval concept lattice structures and further mine the effective association rules, the interval concept lattice structure update algorithm is proposed based on the changes of parameters. According to the analysis of the update degree of the lattice structure, the interval parameter optimization model of concept lattice is built. The method of parameter approximation is employed to obtain a strategy of finding optimal parameters, and thus the problem of subjective and unpredictable parameters is solved. Finally, the instance is utilized to demonstrate the effectiveness of the proposed method and model.
