Abstract

Abstract: In order to quickly search the interest concepts for users，it provides an analysis way for formal concept analysis of attributes constrained by equivalent relation.It first gives a definition between attributes constrained by equivalent relations，and discusses some relative properties.Afterword，based on the above result，for the concept constrained by the equivalent relations，the construction of them in lattice theory is obtained.In addition，some properties of this construction are dealed with.Finally，a real example shows its significance in real life.

Key words: attribute, equivalence relation, constraint, concept

摘要： 为了使用户快速的对感兴趣的概念进行搜索，提出了一种等价关系约束属性的概念分析方法。给出了属性间等价的定义并讨论了相应的性质，在此基础上通过属性等价约束关系得到了一种格结构理论，并处理了它们之间的一些性质。通过一个实际例子，说明了此方法的现实意义。
