| description | The embodiment of the invention provides a construction method, device and equipment of a defrauding and refunding tax identification model, and a storage medium. The method for constructing the cheating and offering tax refund identification model comprises the following steps: acquiring a plurality of sample tax refund application data sequences and corresponding entity tags; determining a corresponding first feature vector based on the sample tax refund application data sequence; and based on the plurality of first feature vectors and the corresponding entity tags, training a pre-constructed defrauding, offering and refund identification model. According to the method for constructing the defraud tax refund identification model, the characteristics of the sample tax refund application data can be directly mined to construct the defraud tax refund identification model, and the problem that evaluation indexes, index weights and index thresholds need to be set depending on expert experience in an existing exp |
