Abstract

The invention provides a risk text extraction method and device, electronic equipment, a computer readable storage medium and a computer program product. The method comprises the steps of performing feature extraction on a to-be-processed text containing a plurality of text segments through a feature extraction layer of a risk classification model to obtain a feature value corresponding to each text segment, wherein the risk classification model is used for performing classification of at least two risk categories on a to-be-processed text; through a prediction layer of the risk classification model, based on the feature values corresponding to the text segments, determining association degrees between the corresponding text segments and the risk categories; and respectively selecting the text fragments of which the association degree with each risk category meets an association degree condition from the plurality of text fragments, and taking the selected text fragments as risk texts extracted from the to-be-processed text. Through the method and the device, the instantaneity of risk text extraction can be improved.

Description

technical field [0001] The present application relates to text processing technology, in particular to a risk text extraction method, device, electronic equipment and storage medium. Background technique [0002] With the development of information technology, various types of information have increasingly penetrated into all aspects of people's lives. Nowadays, when people browse information, they often encounter risk information with negative impacts, such as fraudulent information, which are often difficult to access. Being directly and artificially identified by people will cause a certain negative impact on people, such as economic losses after being cheated. Therefore, in order to avoid the occurrence of the above-mentioned negative effects, it is necessary to extract risk information from the text information provided for users to browse. [0003] In related technologies, in order to extract risky texts from texts to be processed, a common practice is to artificially...
