  • Publication number: 20200372424
    Abstract: One embodiment of the present disclosure provides a system and method for generating risk-control rules. During operation, the system can obtain a first data set and a second data set. The first data set can be associated with a first set of events in a first domain. The second data set can be associated with a second set of events in a second domain. The system can combine the first data set and the second data set to generate a sample data set and train a statistical model by applying the sample data set to determine a set of weights. The system can determine a set of conditions based on the set of weights. Next, the system can generate a set of risk-control rules based on the set of conditions. The system can then apply the set of risk-control rules to a current event in the second domain to determine a credibility of the current event.
