中文摘要：

本文提出一种与传统算法不同的基于n阶形式背景核的概念格构造方法．n阶形式背景核是一类形式背景（具有n个属性）的最小完备子集，使得任意一个n阶形式背景必同构于它的某一个元素．形式背景核用于支持生成子形式背景的小概念格，经过重构小概念格得到最终的概念格．通过实现过程中的所有算法，开发出了一个软件系统IsoFCA．实验表明，在符合实际应用的情况下，基于n阶形式背景核的概念格构造方法优于Godin算法．

英文摘要：

A method based on n^th-order context kernel different from traditional algorithms for concept lattice constructing, is suggested in this paper. The context kernels support generating small lattices for sub-contexts split by a given context. The final concept lattice is reconstructed by combining these small lattices. All relevant algorithms are implemented in a system IsoFCA. Test shows that the method yields concept lattices in lower time complexity than Godin algorithm in actual case.
