| 摘 要： | 不相容规则可能是信息系统中的异常信息,在这个信息时代,这些异常信息与那些"正常"信息同样重要.在总结了许多不相容规则处理算法的不足之后,提出了一种基于熵的不相容规则的修正算法.根据设定的可信度值,使用这个算法可以判断出一个信息系统中不相容规则是否是异常规则.最后结合一个实例阐明了该算法的基本思路.

| Abstract: | Exceptional rules may be exceptional information of information systems,these exceptional information is as important as those of normal information in modern times.This paper summed up much shortcoming of many algorithms of processing incompatible rules and presented a correcting algorithm of incompatible rules based on entropy.According to confidence which the paper assigned,it can judge whether rules of information system are exceptional rules.An example was given to demonstrate the main idea of this alg... |
