System and method for achieving user loss prediction in data information communication network

The invention relates to a system and method for achieving user loss prediction in a data information communication network. The system comprises a data collection and extraction module, a data analysis module, a data modeling module and a prediction module. The data collection and extraction module collects user data of a data information communication network and extracts user experience original data. The data analysis module generates user experience index data. The data modeling module builds a prediction model. The prediction module inputs the user experience index data to the prediction model and judges whether a user is possibly lost or not according to the prediction result. By the adoption of the system and method for achieving user loss prediction in the data information communication network, the basic causes of user loss can be found, operators are informed in time to adopt corresponding measures, more time is obtained for adopting the measures, the service quality of customer service departments
