Abstract

The invention discloses an abstract automatic generation method and apparatus, an electronic device and a storage medium. The method comprises the steps of performing calculation on an original text and a named entity in the original text based on two trained embedded vector models to obtain a first character vector and a second character vector of each single character, and performing splicing toobtain a word vector of each single character; encoding and decoding the word vectors of each single character through the trained Transformer encoding and decoding model to obtain the word vectors of the multiple generated words, so that the feature representation capacity of the word vectors of the multiple generated words can be enhanced, and dividing each generated word into the first type ofgenerated words or the second type of generated words; and calculating the first type of generated words and the second type of generated words by adopting a trained pointer network and a trained memory network respectively to obtain first type of output words and second type of output words, and forming a target abstract by a plurality of first type of output words and / or a plurality of second type of output words, so that the problem that a remote named entity cannot be generated can be effectively solved.

Description

technical field

[0001] The present invention relates to the field of natural language processing, in particular to an abstract automatic generation method, device, electronic equipment and storage medium. Background technique

[0002] Automatic summarization refers to the automatic generation of short texts that can summarize the original text by means of algorithms for a piece of original text. At present, automatic summarization algorithms are mainly divided into extractive automatic summarization and generative automatic summarization. Extractive automatic summarization refers to extracting one or more sentences with generalization ability from the original text as an abstract in units of sentences, but this method is difficult to adapt to the changeable original text content. Generative automatic summarization generates abstracts by excavating deeper semantic information to paraphrase and summarize the central idea of ​​the original text. The content of the abstract is ...
