Research of insurance fraud risk based on bayesian networks

Bayesian network is able to make full use of prior knowledge and finite sample data. Due to the characteristics of being hard to be quantized,this paper models one specific insurance operational risk-fraud risk with Bayesian network by establishing the topology and determining the value of nodes and parameters. It manages to analyse fraud risk by probabilistic inference ability of Bayesian network,which provides operation mode and decision basis to the management of insurance fraud risk.
