Abstract

The embodiment of the invention provides an invoice category identification method and device, electronic equipment and a readable storage medium. The method is applied to the technical field of datamining and comprises the steps that invoice information input by a user and aiming at an invoice to be identified is acquired, and an invoice code set to which the invoice to be identified belongs isdetermined according to keywords in the invoice information and an invoice sample training set acquired in advance; for each invoice code in the invoice code set, calculating a posterior probability value of the invoice to be identified belonging to the invoice code through a naive Bayes algorithm according to the keyword and the invoice sample training set; and taking the invoice code corresponding to the maximum posterior probability value as the invoice code of the invoice to be identified. Compared with the prior art, the invoice type identification efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of data mining, in particular to an invoice category identification method, device, electronic equipment and readable storage medium.
