Abstract

An embodiment of the present specification provides a computer-executed text risk prediction method and apparatus. According to one embodiment of the method, after obtaining a text to be predicted, onthe one hand, keyword features of the text are analyzed, and part-of-speech related features are analyzed for words in the text; On the other hand, mining the important vocabulary in the text, so asto get more related vocabulary and generate extended features. Furthermore, the paper analyzes the keyword features, part-of-speech related features and extended features of the text comprehensively to determine the risk of the text. This embodiment can improve the accuracy of text risk prediction.

Description

technical field [0001] One or more embodiments of this specification relate to the field of computer technology, and in particular to a method and device for risk prediction of text by computer. Background technique [0002] With the development of network technology, there are various contents on the Internet. Due to the open nature of the Internet, the content posted by one user on the Internet may be seen by multiple users. At the same time, some illegal and illegal activities can also be carried out through the Internet. Therefore, it is of great significance to monitor the risk of users' published texts. For example, for scenarios such as public opinion control, anti-fraud, cross-border sales restrictions, anti-money laundering, text spam, etc., it is very important to identify the risk of text. [0003] In conventional technologies, the riskiness of text is often identified by methods such as character matching with risky words in the blacklist, edit distance, hash ...
