摘要: 文中首先描述了负关联规则的基本概念,接着分析了负关联规则挖掘的特点和相关算法,并提出基于相关性和剪切策略的改进算法来进行正、负关联规则挖掘,最后指出了负关联规则挖掘的研究方向.Abstract: This paper presents the basic concepts of negative association rules firstly. Then the characteristic of negative association rules is analyzed and some algorithms are introduced. With a correlation coefficient measure and pruning strategies,we present an efficient algorithm for mining both positive and negative association rules in databases. At last,we point out the research object.
