中文摘要：
以形式概念分析（FCA）理论为基础,提出一种基于属性结构偏序图的中药方剂配伍规律分析的知识表示方法。该方法将方剂和药物定义为对象和属性,并通过概念之间的层次结构关系,将方剂数据库的知识结构清晰地表现在属性结构偏序图上,并从中发现方剂配伍规律。实例结果表明该方法用于方剂配伍知识发现研究对小背景是可行的,对于大背景的处理问题是形式概念的第13开放问题（4th International Conference on Formal Concept Analysis,ICFAC,2006）,是目前国际上亟待解决的研究课题。
英文摘要：
On the basis of the theory of formal concept analysis （FCA）, a new method for generation of an attribute hierarchical graph is proposed in this paper. This method can solve the problems of how to mine and express classification knowledge and rules in compatibility of prescription. In this paper, we view prescriptions as objects that possess certain attributes of the named drugs. First, the formal context is established based on theory. Then optimization of the original formal context and extracts the connotation and extension of the concept are followed, constructing attribute hierarchical graph. Finally, useful knowledge from the hierarchical diagram of attributes based on the way of knowledge representation is mined. The result showed that the method for discovering Traditional Chinese Prescription （TCP） diagnostic knowledge is feasible and effectual for small samples. The research of large samples is 13th open question of FCA. It is an international subject to be studied urgently.
