Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0027] Such as figure 1 As shown, the present invention provides a method for automatically generating text summaries based on heuristic rules, including:

[0028] S1. Using the paragraph and sentence order of the text as the heuristic word order, divide the news text into the beginning paragraph, the middle paragraph and the end paragraph, and heuristically segment each paragraph at the granularity of sentences and fragments;

[0029] S2. First, take the sentence as the granularity, extract the target sentences of each paragraph respectively, and obtain the sentence abstract set of each paragraph, and then use the fragments in the sentence abstract collection as the granularity, respectively extract the target fragments of each paragraph, and obtain the fragm...

Abstract

The invention discloses a method for automatically generating text summaries based on heuristic rules, including: S1, using the paragraphs and sentence sequences of the text as the heuristic word order, dividing the news text into the beginning paragraph, the middle paragraph and the end paragraph, and using sentences and fragments Carry out heuristic segmentation of each paragraph as the granularity; S2, first take the sentence as the granularity, extract the target sentence of each paragraph respectively, obtain the sentence summary set of each paragraph, and then take the fragments in the sentence summary set as the granularity, respectively extract each The target segment of a paragraph is obtained by obtaining a segment summary set of each paragraph; S3, removing redundant segments in the segment summary set, and combining the selected segments according to the sequence in which the segments appear to generate a text summary. And, a device for automatically generating text summaries based on heuristic rules. The sentence organization of the text summary generated by the method of the invention has good coherence and strong readability.

Description

technical field [0001] The invention relates to the field of natural language processing. More specifically, the present invention relates to a method and device for automatically generating text summaries based on heuristic rules. Background technique [0002] The process of automatic summarization is mainly to summarize the central meaning of the text document, and the purpose is to create a summary that contains the main content of the original document. It has significant application scenarios in news, finance, medical and other fields. Especially in the current Internet information age, information overload makes people eager to learn the most and most useful text information in the shortest time, and the automatic generation technology of text summarization makes this requirement come true. [0003] The automatic summarization technology takes the entire article as input, and generates a paragraph of refined words to express and summarize the core content of the inpu...
