摘 要:目前衡量和生成关联规则的主要准则是考虑支持度和置信度阈值,而在实际应用中仅按此准则来挖掘是不够的,这主要是因为关联规则的评价标准不合理产生的.针对关联规则评价指标进行了深入的研究,分析了"支持度-置信度"架构的局限性,提出了基于相关性的兴趣度的评价指标PS公式,根据其数学特性指出了它的优点与不足,为关联规则评价体系的改进奠定了理论基础.Current main guidelines is to measure and generate Association rules take into account support and confidence threshold, and only in the practical application of this guideline to mining is insufficient, this is mainly because the associated rule evaluation criterion is not reasonable. This article for the associated rule evaluation conducted an in-depth study, analyzed the "support-confidence" schema limitations, presenting an interest based on correlation degree of evaluation indicators PS formula, based on its mathematical properties that has its advantages and disadvantages, laid the theoretical foundation for improvement of evaluation system of Mining Association rules.
