中文摘要：
区间集概念格是对形式概念分析理论的扩展，也是形式概念分析与区间集理论相结合的产物。区间集概念所反映的是人类认知的动态描述，它比形式概念更复杂，而在此基础上形成的区间集概念格也更为复杂。文中在研究区间集概念格与概念格之间关系的基础上，提出了一种构造区间集概念格的方法，其主要思想是将概念格中的形式概念在某种合适规则下融合成区间集概念。最后给出了该方法相应的算法。
英文摘要：
Interval-set concept lattice is an extension of formal concept analysis （FCA）, which is a product of the combination between FCA and the interval-set theory. Interval-set concept is a reflection of the dynamic description of human cognition, and it is more complicated than formal concept. On the basis of the formation, the interval set concept lattice is also more complicated. Aiming at the construction simplification of an interval set concept lattice, the connections between the Interval-set concept lattice and the concept lattice are studied, and furthermore an approach to constructing the interval set concept lattice is proposed. The main idea is to fuse formal concept of the corresponding concept lattice into interval-set concept under some rules. Lastly, the corresponding algorithm of constructing interval-set concept lattice is given.
