When some attributes of a formal context can be decomposed into some subattributes a model of layered concept lattice to improve the efficiency of building concept lattice with complex structure attribute data is studied, the relationship between concept lattice and layered concept is discussed. Two algorithms are proposed: one is the roll-up building algorithm in which the upper concepts are built by the lower concept and the other is the drill-down algorithm in which the lower concepts are built by the upper concept. The examples and experiments show that the layered concept lattice model can be used to model complex structure attribute data, and the roll-up building algorithm and the drill-down algorithm are effective. The layered concept lattice model expands the scope of the research and application of concept lattice, the roll-up building algorithm, and drill-down algorithm of layered concept lattice to improve the efficiency for building concept lattice.

分层概念格模型及其在快速构建概念格中的应用

当可以将形式上下文的某些属性分解为子属性时，可以使用分层概念格模型来提高具有复杂结构属性数据的概念格构建效率，讨论了概念格与分层概念之间的关系。提出了两种算法：一种是向上构建算法，其中上部概念由下部概念构建，另一种是向下钻取算法，其中下部概念由上部概念构建。实例和实验表明，分层概念格模型可用于复杂结构属性数据的建模，并且有效的建立滚动算法和向下钻取算法。分层的概念格模型扩展了概念格的研究和应用范围，
