摘要
分别讨论了关联规则的客观评价指标(支持度、可信度和相关强度)和主观评价指标(新颖性、用户感兴趣性和简洁性),在此基础上给出了一种关联规则的综合自动评价方法,并结合实例验证了该方法的有效性。
The objective evaluation measures(support,confidence,and correlation intensity) and the subjective evaluation measures(novelty,simplicity,and user interest degree) of association rules were discussed respectively. On basis of this discussion,a kind of comprehensive automatic evaluation method of association rules was introduced,and a practical example was given to demonstrate its validity.
