摘要:尝试重新定义了正关联规则和负关联规则,并给出它们的兴趣度,从而统一了正、负关联规则的评价标准.在此基础上,采用逻辑的方法查找极小矛盾集以判定关联规则集的一致性,通过修改极小矛盾集中的规则消除关联规则集的不一致,从而优化原有的关联规则集.

关键词: 数据挖掘, 关联规则, 评价

Abstract: The concepts of positive association rule and negative association rule are redefined,and the interest degree of the rules is brought out.Therefore,the evaluation standard of the positive and the negative association rules is conformed.On the basis of the above,the inconsistency of association rule set is solved tentatively by logical method and its expressive power is increased further.As a result,the author optimizes the original association rule set.

Key words: data mining, association rule, evaluation
