Abstract

The invention provides a text classification method and device, and the method comprises the steps: determining a plurality of basic keywords in a to-be-classified text, determining the importance degree of the basic keywords in the text, when a label keyword located in a preset label classification keyword table is determined in the multiple basic keywords, weighing the basic weight of the labelkeyword to increase the weight of the label keyword, meanwhile, determining related keywords associated with the label keyword based on a preset word vector model, determining the related keywords associated with the label keyword based on a preset word vector model so that missing of low-frequency keywords is prevented, and finally, comprehensively determining the classification result of the text according to the corresponding relationship between the keywords in the tag classification keyword table and the classification result, the basic keywords, the tag keywords, the related keywords andthe respective corresponding weight values so as to improve the accuracy of the classification result.

Description

technical field [0001] The invention belongs to the technical field of the Internet, and in particular relates to a text classification method and device. Background technique [0002] With the continuous development of Internet technology, more and more people obtain useful information through the Internet.
