| 摘 要： | 关联规则挖掘是数据挖掘领域的一个重要课题。负关联规则相比正关联规则反映了不同的决策问题,有着重要的研究意义。目前负关联规则的兴趣度度量主要采用传统的基于支持度-置信度框架的度量方法。然而这些传统的度量方法存在一些局限,如标准不客观、不能反映项集间的相关性等,为了克服这些问题,本文提出一种基于余弦度量的兴趣度度量方法。

| Abstract: | Association rule mining is an important topic in data mining field. Negative association rule reflects the different decision problems compared to the positive association rules, which has important significance. The measure of negative association rules was based on the traditional method using support-confidence framework. However, the traditional measurement method has some limitations, such as the standard is not objective, cannot reflect the correlation of association rule and so on. In order to overcome these problems, this paper proposed an interestingness measurement method based on the cosine metric. |
