形式概念分析中的对象概念与属性概念

摘要

为了进一步提高数据表示和数据挖掘的效率，对两类特殊概念即对象概念和属性概念进行了研究。分析了对象概念和属性概念与不可约元的关系，提出了对象概念和属性概念的识别算法；提出了以属性概念为递归终止条件的计算内涵缩减递归算法；研究了属性排序以及属性序列在规则提取中的应用。%In order to further facilitate data representation and improve the efficiency of data mining, two kinds of special con-cepts, namely object concept and attribute concept are studied. This paper analyzes relationship between object concepts(or attri-bute concepts)and irreducible elements, and recognition algorithms of object concepts and attribute concepts are put forward. A recursive algorithm for intent reduction which has attribute concepts as termination condition is given. Attributes sequence as well as its application in association rule extraction is studied.
