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 summary generation device based on an attention encoder, comprising: a sentence encoder for acquiring documents and dividing the documents into multiple sentences; a document encoder for combining the multiple sentences with multiple A document representation is obtained for the relationship between the sentences; a sentence extractor is configured to extract a sentence used as an abstract according to the plurality of sentences and the document representation. It can better capture the connection and dependency between sentences, so as to accurately extract the summary, and can display richer information when generating the summary.

Description

Technical field [0001] Summary The present invention relates to a document extraction technology, and particularly relates to a news summary based on the removable attention encoder generating means. Background technique [0002] With the rapid growth of current news data, the development of automatic summarization system needs more urgent. Removable text excerpt is to be generated by extracting a summary sentence significant primary documents that contain information from a document, such summary generated more fluent. Show the encoded power in resolving serialization problems - decoding architecture has been successfully applied to generate a decimated snippets in which the encoder reads the source sentence and vectors of fixed length representation, then the decoder outputs the prediction for each sentence label, that the decision whether to extract a sentence as part of the summary. [0003] However, the existing problems for the automatic summarization based encoding - for m...
