Express waybill number identification method, device and equipment based on machine learning

The invention relates to an express waybill number identification method, a device and equipment based on machine learning. The method comprises the steps of obtaining a to-be-identified target express waybill number; inputting the target express waybill number into a pre-trained express waybill number identification model to obtain an identification result; and determining an express company corresponding to the target express waybill number based on an identification result. According to the setting, a user does not need to manually compile an identification rule, and the identification rulecan be automatically generated, so that the efficiency is higher, careless omission does not easily occur, and meanwhile, the identification accuracy can be ensured under the condition that historical data is enough. Besides, when rules of express waybill numbers are modified or express companies are newly added, the machine learning algorithm can automatically correct the recognition model without manual intervention, s
