基于可信度的异常规则修正法

Abnormal Rule Correction Method Based on Confidence Degree

在这个信息时代,信息系统中的异常信息同那些"正常"信息同样重要。论文在总结了许多异常规则处理算法不足的基础上,提出了一种基于可信度的异常规则修正法。该方法根据设定的可信度阈值,来判断信息系统中的不相容规则是否是异常规则。论文结合一个实例阐明了该方法的基本思路。

Abnorma rules may be exceptional information of information systems,these exceptional information are as important as those of normal information in modern times.This paper summed up much shortcoming of many algorithms of processing abnormal rules and presented an abnormal rule correction method based on confidence degree.According to confidence degree which the paper assigned,the proposed method can judge whether rules of information system are abnormal rules.An example is given to demonstrate the main idea of this method.
