Problems solved by technology

For example, if there is a change in the news video of a local TV station, if the leader of the city changes, the recognition accuracy will not be high because the name of the new leader has not appeared in the original news corpus
For another example, before the domestic movie "The Wandering Earth" was released in 2019, the author "Liu Cixin" was relatively unpopular. After that, the frequency of appearances in the news increased sharply with the popularity of the movie, but because the word rarely appeared in the news corpus Therefore, the recognition accuracy is not high

Abstract

The invention discloses a news content recognition method, and a model training method and device, and aims to improve the recognition accuracy of new words and unpopular words in news content. The news content recognition model training method comprises the following steps: capturing news text content from a network within a preset time period from nowadays by utilizing a web crawler technology; taking the currently captured news text content as the latest news corpus, and combining with a pre-stored background picture and a word stock to synthesize a training set; and training a news content identification model by using the training set.

Description

technical field [0001] The present invention relates to the technical field of character recognition, and more specifically, to a news content recognition method, a model training method and a device. Background technique [0002] The continuous emergence of new words in natural language is an objective law. With the rapid development of social economy and the increasing frequency of foreign exchanges, especially the widespread use of the Internet, it provides a broad space for the emergence and popularity of new words. In addition, some unpopular words may also become hot words due to sudden hot spots of public opinion. [0003] In the field of news, vocabulary is updated frequently. Because new words have never appeared in the corpus, and unpopular words rarely appear in the corpus, when they are recognized based on the original news corpus, the recognition accuracy is not high. For example, if the news video of a TV station in a certain city changes, the recognition accu...
