Method, device and computer-readable storage medium for tax type authentication

Abstract

The embodiment of the invention discloses a tax type authentication method and device and a computer-readable storage medium. A tax type database is established in advance; The business scope information to be processed is processed by word segmentation to obtain the eigenvector. According to the matching degree between the feature vector and the feature information in the tax category database, the tax category corresponding to the business scope information is determined. In the technical scheme, the pre-established tax category database contains the characteristic information correspondingto each tax category, and the tax category database is equivalent to a unified standard for evaluating the business scope information, which effectively solves the problem that the standards of tax personnel are not unified and leads to errors or divergences in classification. And the use of tax and fee type database to match the business scope information, to achieve the automatic authenticationof tax and fee types, reduce human intervention, reduce the workload of tax staff, improve the processing efficiency of tax and fee type certification.

Description

technical field [0001] The present invention relates to the technical field of taxation systems, in particular to a tax type authentication method, device and computer-readable storage medium. Background technique [0002] The types of taxes and fees include industry categories, collection items and other categories. In the traditional way, the industry category of the enterprise is determined by the staff of the tax bureau through the business scope of the enterprise to determine which industry it belongs to.

AI Technical Summary

Problems solved by technology

[0003] Due to the different environments of the business personnel of each tax bureau, the subjective standards of each tax staff are not uniform; there are hundreds of industries and collection items, and it is difficult for the human brain to complete the correspondence from memory, which has caused many taxpayers The definition of the industry is not clear, and some are even obviously wrong; the large number of taxpayers will inevitably lead to busy tax staff and crowded tax office halls

Due to the one-to-many relationship between business scope, industry and collection items, and some sample data errors, it is difficult to directly use machine learning algorithms to achieve classification
