Problems solved by technology

[0003] However, existing encoder-decoder structure-based methods for automatic summarization problems pay too much attention to the decoder part, i.e., these methods usually use the attention mechanism in the decoding part instead of collecting more information about the document in the encoder
Their focus is on obtaining sentences that are more related to the source document, but they ignore the relationship between different sentences

Abstract

An extractive news digest generation apparatus based on an attention encoder includes a statement encoder for acquiring a document and dividing the document into a plurality of sentences; a document encoder for acquiring a document representation according to the relationship between the plurality of sentences and the plurality of sentences; a statement extractor for extracting sentences used as summaries from the plurality of sentences and the document representations. The extractive news digest generation apparatus can capture the relationship and dependency between sentences better, so as to extract abstracts accurately and show more abundant information when generating abstracts.

Description

technical field [0001] The invention relates to the technical field of document abstract extraction, in particular to an extractive news abstract generation device based on an attention encoder. Background technique [0002] With the rapid increase of current news data, the demand for the development of automatic summarization system is becoming more and more urgent. The method of extractive text summarization is to generate a summary by extracting sentences that obviously contain the main information of the document from the document, so that the generated summary is more fluent. The encoder-decoder structure, which has shown great power in solving serialization problems, has been successfully applied to generate extractive summarization, where the encoder reads in the source sentence and represents it with a fixed-length vector, and the decoder outputs the predicted Label, which decides whether to extract a sentence as part of the summary. [0003] However, existing enco...
