Abstract

The invention belongs to the field of natural languages, particularly provides an extraction and generation hybrid abstract generation method, and aims to solve the problems of an existing extractiontype automatic abstract method and an existing generation type automatic abstract method. The invention provides an extraction and generation hybrid abstract generation method. The method comprises the steps: replacing entities and numbers in a document are recognized, and the entities and the numbers in the document with preset labels; Extracting a plurality of first key sentences from the document subjected to label replacement by utilizing an extraction type document abstract extraction method; Compressing the plurality of first key sentences respectively to obtain second key sentences corresponding to the first key sentences; Selectively taking the first key sentence or the second key sentence as a first to-be-synthesized key sentence through a comparison result of the length of the first key sentence and a preset length threshold; And generating the abstract of the document according to all the first to-be-synthesized key sentences. The method provided by the invention not only can generate the abstract conforming to the semantic expression of the document, but also can ensure the readability.

Description

technical field [0001] The invention belongs to the technical field of natural language, and in particular relates to a method for generating a hybrid abstract by extraction and generation. Background technique [0002] Automatic summarization is a technology that uses computer systems to automatically implement text analysis, content induction, and automatic abstract generation. It can express the main content of the original text in a concise form according to the requirements of readers (or users). Automatic summarization technology can effectively help readers (or users) find interesting content from retrieved articles, and improve reading speed and quality. This technique can compress a document into a more concise expression, and it is guaranteed to cover valuable topics of the original document. [0003] Existing automatic summarization techniques mainly include two methods: extractive automatic summarization method and generative automatic summarization method. The...
