Abstract

The invention discloses an abnormal text recognition method and device, computing equipment and a medium, and the method comprises the steps: inputting a to-be-recognized text into a named entity recognition model, so as to determine candidate entities contained in the text, wherein the candidate entities comprise names, organization names or dates; inputting a to-be-recognized text into the topicrecognition model for processing so as to recognize a topic category of the text; if the topic category of the text corresponds to a preset topic, for each candidate entity in the text, inputting a vector set corresponding to the candidate entity into an emotion recognition model to obtain an emotion tendency of the text to the candidate entity; and if the emotional tendency is negative, judgingthat the text is an abnormal text under a preset theme.

Description

technical field [0001] The present invention relates to the field of natural language processing, in particular to an abnormal text recognition method, device, computing device and medium. Background technique [0002] Nowadays, many government functional departments, financial institutions, merchants, etc. will send targeted SMS through the operator's SMS platform channel. For example, in the event of thunderstorms such as rainstorms, the Meteorological Bureau of the local government will use the channel of the SMS platform to send reminder text messages to users whose numbers belong to the region in consideration of safe travel. [0003] However, as an open platform, the SMS platform channel will also be used by some criminals to send political-related SMS to ordinary users, attacking or discrediting the country. This kind of behavior not only violates relevant national laws and regulations, but also brings great public opinion risks to the normal operation of the platfor...
