Abstract

The invention relates to the technical field of language processing, and particularly discloses a news abstract generation method and device and computer equipment. The news abstract generation method comprises the following steps: preprocessing news data to obtain a single sentence text set; reordering the single-sentence texts in the single-sentence text set according to a first preset importance ordering algorithm to obtain a first abstract candidate sentence set; extracting a plurality of keywords from the single sentence text set, and sorting the plurality of keywords according to a second preset importance sorting algorithm to obtain a keyword set; extracting an abstract first sentence from the single sentence text set; and performing logic splicing based on the first abstract candidate sentence set, the keyword set and the first abstract sentence to obtain the news abstract. Therefore, the formed news abstract has good generality, continuity and logicality.

Description

technical field [0001] The present invention relates to the technical field of language processing, in particular to a method, device and computer equipment for generating news summaries. Background technique [0002] Text Summarization (Text Summarization) is a common basic task of Natural Language Processing (Natural Language Processing, NLP). It refers to the extraction and refinement of text or text collection data through various techniques or methods, and summarizes its gist. [0003] Text summarization algorithms are mainly divided into extraction and generation. Among them, the extraction method is to directly select representative phrases, sentences or paragraphs from the original text to form a summary of the original text. However, conventional extraction algorithms are often designed only from the generalization of sentences to text, and the resulting text summaries often lack logic and coherence. Contents of the invention [0004] Based on this, it is necessa...
