Embodiment Construction

[0018] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0019] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.

[0020] In order to improve the accuracy of news classification, the present invention proposes a news classification method and a computer-readable storage medium, and adopts the idea of ​​data enhancement, that is, word segmentation and recombination are carried out on the original limited training set to obtain more training data. Finally, the training data of all kinds of news is balanced, and then the BERT model is used...

Abstract

The invention discloses a news classification method and a computer readable storage medium, and the method comprises the steps: obtaining original data which comprises a news text and a news category; determining the total number of news texts under each news category; when the total number of the news texts under a certain news category is smaller than a preset threshold value, carrying out dataenhancement processing on the news texts under the news category, so that the total number of the processed news texts under the news category is not smaller than the preset threshold value; and respectively screening out news texts with the same number as the preset threshold from all news texts under each news category as training data, and inputting the news texts into a BERT model for training. According to the news classification method and the computer readable storage medium, the classification accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a news classification method and a computer-readable storage medium. Background technique [0002] In recent years, with the rapid development of computer technology and network communication technology, traditional ways of obtaining information such as TV, radio, and newspapers are no longer the main way for people to obtain information, and people begin to pay more attention to network news. The Internet contains a large amount of information, rich content, timely and accurate information, and comprehensive introduction and comparison of relevant information, which can better meet people's needs for information. However, with the development of Internet technology and the high popularity of smart devices, the information explosion has become an increasingly difficult problem. How to help all kinds of people accurately and quickly obtain valuable information from...
