Problems solved by technology

[0004] The classification identification and entity extraction methods of spam text messages in the prior art, due to the short text text of spam text messages and many classifications, the accuracy of the classification results of spam text messages is poor, and because the writing of spam text messages is not standardized, there are homonyms, homonyms, etc. meaning variants, so the effect of entity extraction on spam messages is also poor

Abstract

The invention discloses a junk short message classification and identification method and device, computer equipment and a storage medium. The method comprises the steps of performing text filtering on a short message text set to obtain a junk short message text set; sequentially inputting the junk short message text set into a first-level classification model and a second-level classification model to obtain a plurality of categories of junk short message text sets; and inputting each type of junk short message text set into the entity information extraction model to obtain each type of junkshort message text set after the entity information is identified or restored. By using the technical scheme of the invention, accurate classification and identification of massive short messages canbe realized, and entity information in junk short messages can be accurately extracted.

Description

technical field [0001] The embodiments of the present invention relate to data processing technology, and in particular to a method, device, computer equipment and storage medium for classifying and identifying spam short messages. Background technique [0002] As a large-scale information exchange platform, SMS provides convenience for the transmission of daily information. However, some criminals transmit spam information through the SMS platform, which has caused adverse effects on social security management and people's daily life. [0003] There are a large number of SMS texts in the SMS platform. Before sending SMS texts, operators need to identify and intercept spam SMS texts, and extract the entity information of the intercepted spam SMS texts, so as to assist the supervision department to trace the information sources of spam SMS messages. , Promote the construction of a green information exchange platform. In the prior art, the text content of a large number of s...
