However, these two methods have certain limitations. The extraction method only focuses on keywords and tends to ignore the integrity of the text; while the abstract method is based on the full text, but the new words used may not be able to replace the original words and cannot reflect the key words of the original text. point

Embodiment Construction

[0060] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present invention will be described in detail below in conjunction with the drawings and embodiments. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in the present application, all other implementation manners obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

[0061] In one embodiment, the present invention provides a method for generating a text summary, including:

[0062] get the input text;

[0063] The encoder is used to process the text to obtain the encoder's environment vector, and the encoder includes a merge layer with a perceptual keyword attention mechanism network;

[0064] Decoder decoding is used to generate a digest based on the encoder's environment vect...

Abstract

The invention discloses a text abstract generation method and device and relates to the automatic abstract technology of natural language texts. After an input text is obtained, the text is processedby adopting an encoder to obtain an environment vector of the encoder, and a decoder is adopted to decode and generate an abstract according to the environment vector of the encoder; a merging layer with a keyword attention sensing mechanism network is added in the whole text information encoding process of an encoder, and a finally obtained environment vector of the encoder is adjusted. The environment vector of the encoder considers integrity of the text and pays attention to keywords in the text, finally, the abstract obtained after decoding by the decoder is more accurate and more consistent with the input text.

Description

technical field [0001] The present invention relates to the technology of automatic summarization of natural language texts, in particular, to a method and device for generating text summaries. Background technique [0002] Text summarization is a challenging task that aims to produce summaries that contain useful information without being redundant. Related technologies can be mainly divided into extraction methods and abstraction methods. Extractive summarization methods identify and connect related words from the original text, while abstraction methods try to express the main content in a concise manner, possibly using words that were not present in the original text. However, these two methods have certain limitations. The extraction method only focuses on keywords and tends to ignore the integrity of the text; while the abstract method is based on the full text, but the new words used may not be able to replace the original words and cannot reflect the key words of th...
