Problems solved by technology

[0004] Although generative summaries can describe the meaning of the main body of the original text, their readability is poor. Different words often repeat meaninglessly, some words have no connection between them, and some summaries are even completely unreadable.
[0005] Extractive summary generates a text summary by extracting sentences from the target text, but this method takes a long time to generate a text summary, and the accuracy of the text summary is not high, and it is difficult to describe the meaning of the original text

Abstract

The embodiment of the invention provides a text abstract generation method and device to achieve rapid and automatic text abstract, and abstract text is high in readability and consistent with an original text main text in meaning. The method comprises the steps of providing and training an abstract generation model comprising an encoder and a decoder; receiving an input text and an original textcode output by the encoder through the decoder; wherein the input text comprises a start character and an abstract text output last time; respectively determining a generation mode probability matrix,an extraction mode probability matrix and a weight matrix through the decoder; based on the generation mode probability matrix, the extraction mode probability matrix and the weight matrix, generating a reference probability matri, wherein the reference probability matrix represents the reference probability of each word in a word list; and determining a current abstract text based on the reference probability of the reference probability matrix.

Description

technical field [0001] The present application relates to the technical field of text information processing, in particular to a method and device for generating a text abstract. Background technique [0002] Automatic text summarization is an important research direction of natural language processing. There are two main methods. One is extractive automatic summarization. Find the sentences closest to the main idea of ​​the full text in the original text, and extract them as a summary of the full text; the other type is generative automatic summarization, that is, after the system reads the original text, on the basis of understanding the meaning of the whole article, press certain The method generates a piece of text word by word or word by word to express the central idea of ​​the original text. [0003] The inventor found in the research that the mode of the prior art mainly has the following problems: [0004] Although generative summaries can describe the meaning of ...
