Problems solved by technology

However, in many cases, especially in the case of polysemous words, it is difficult to determine the semantics of keywords set by users with existing detection methods, and it is even more impossible to search and match through simple synonyms. The detection results obtained by other detection methods still have the problems of low accuracy and narrow scope of application

Abstract

The invention discloses a text detection method and device, and relates to the technical field of text detection, and mainly aims to improve the accuracy of text detection. The main technical scheme of the invention is as follows: obtaining the text to be detected; determining the co-occurrence words of the target phrase; determining a paragraph to be detected in the text to be detected by using the co-occurrence word; detecting whether the paragraph to be detected contains content matched with the target phrase by using a machine learning model; and according to the matching result and the detection rule corresponding to the target phrase, determining whether the text to be detected meets the requirements. The invention is used for normative detection of a text.

Description

technical field [0001] The invention relates to the technical field of text detection, in particular to a text detection method and device. Background technique [0002] With the emergence and development of the Internet, the number of text documents on the Internet has grown more rapidly. Text detection technology has been widely used in document retrieval, public opinion management and other fields. By detecting whether the text contains information such as phrases or sentences set by users It is determined whether the text content contains the data content required by the user. [0003] At present, the commonly used text detection is mostly based on the keyword set by the user for matching, or using natural language processing technology to calculate multiple synonyms of the keyword, and use these words for text detection. However, in many cases, especially in the case of polysemous words, it is difficult to determine the semantics of keywords set by users with existing ...
