Abstract

The present invention discloses a commodity name classification method and system based on semantic similarity expansion. The offline algorithm calculation of historical invoice data sets of commodities of existing categories is carried out to obtain a naive Bayesian model and a word vector of each type of commodities. According to different conditions, whether a commodity name word vector inputted by a merchant exists in the naive Bayesian model of the commodities of the existing categories is analyzed, if the naive Bayesian model does not have a uniterm after a commodity name participle, thecommodity name and existing commodity category keywords are subjected to word vector similarity calculation, the probability that the commodity name inputted by the merchant belongs to an existing commodity category is calculated, and a category corresponding to a maximum value is the category to which the commodity belongs. Experimental results show that the accuracy of the commodity category keyword similarity calculation based on semantic expansion is high, and a calculation result accords with common sense judgment.

Description

technical field [0001] The invention relates to the technical field of e-commerce platforms, in particular to a method and system for classifying commodity names based on semantic similarity extension. Background technique [0002] With the development of the Internet era and the introduction of the national "Internet +" strategy, the tax system has also proposed strategic ideas such as "information management tax" and "Internet + taxation" on the basis of "controlling taxes with tickets" to promote my country's The upgrading of tax collection and management can avoid the phenomenon of businessmen evading taxes by not issuing invoices, wrongly issuing invoices, or falsely issuing invoices. Therefore, how to standardize the issuance of invoices and reduce tax risks has become an urgent problem to be solved. [0003] Among them, ensuring that the product names issued by merchants are authentic and credible is one of the effective ways to standardize invoicing, that is, similar ...
