To avoid this,this system automatically verifies and compares the accuracy rate of each rule when the system analyzes monthly user payment records.
If the accuracy rate of a rule is lower than the set threshold value, the system highlights it for review and the providers decide whether to delete it.
Next, providers may use new data and the constructed model to produce a new rule. If the new rule is verified, the system will add the rule to the database thus maintaining the system’s predictive power.
After the system is built, the provider spends six months conducting verifications.
A comparison of the data from providers indicated that, even though the testing environment was different from the conditions at the providers,the efficacy rules produced by CM-CoP is greater than that of existing rules used by telecom providers. Thus, the two main contributions of this work are described as follows
