Bill classification method and device, equipment and storage medium

The invention discloses a bill classification method and device, equipment and a storage medium. The method comprises the steps: obtaining to-be-processed bill data, carrying out the OCR recognition of the to-be-processed bill data, and obtaining target format data; inputting the target format data into a preset bill recognition model, and performing semantic calculation based on a preset attention mechanism on the target format data based on the preset bill recognition model to obtain candidate results; based on the size of each candidate result, obtaining a classification result of the to-be-processed bill data; wherein the preset bill recognition model is obtained by performing iterative training on a preset basic model based on preset feature data with a preset classification label and a preset attention mechanism. According to the embodiment, the target format data can be automatically and accurately processed based on the preset bill recognition model, and the classification result of the to-be-processe
