Abstract

The invention provides a text identification method and apparatus. The text identification method comprises the steps of obtaining a to-be-identified text; performing text identification on the to-be-identified text through a one-level model and a two-level model, wherein the one-level model is a text identification model generated by utilizing corpora in latest unit time in a corpus library, and the two-level model is a text identification model generated by utilizing the corpora in the corpus library; and outputting an identification result of the to-be-identified text. According to the method and the apparatus, the to-be-identified text is subjected to text identification through the one-level model and the two-level model, so that the accuracy of junk text identification can be improved and the accuracy fluctuation in continuous updating change of junk text contents can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a text recognition method and device. Background technique [0002] Text classification refers to the automatic classification and marking of text sets according to certain classification systems or standards. Text classification generally includes the process of text expression, classifier selection and training, classification result evaluation and feedback. [0003] The main idea of ​​the existing spam text recognition scheme is to use the known spam text content as the input of the text classification algorithm to perform machine learning training to form a model. In the model, the feature items of the known spam text content are extracted to summarize the formation rules, and then evaluated Whether the unknown text content matches the spam feature information in the model is used to determine whether it is spam. [0004] Existing spam text recognition schemes use a ge...
