The invention discloses a
risk assessment method and
system based on water
charge recovery, and the method includes obtaining sample data of a water user, establishing a tag
library for water users, forming a portrait of the risk of water fee
recovery, training the risk portrait of water
charge recovery and generating the classification model, and solidifying the classification model, monitoringbusiness
system database in real time, and when the
data source changes are detected, analyzing the user sensitive data and generating real-time user tags; generating public opinion tags by combiningthe data of Internet public opinion
system and crawler tools; according to the real-time user tags, public opinion tags and tag
library tags, evaluating the risk of user water
charge recovery by the solidified classification model. The system is used to implement the
risk assessment method described above. The
risk assessment method provided by the invention not only can periodically calculate therisk of water charge
recovery, but also can identify the risk of water charge
recovery in real time, thereby reducing or avoiding the situation that the water user does not pay the water charge on time.
