Problems solved by technology

[0003] Most of the existing PDF and HTML text extractions directly output the extracted text line by line without segmentation; or perform segmentation according to the extra blank lines found, but this situation is not very common, and for documents The output of the form is very unfriendly

Abstract

The invention relates to the field of text processing. In view of the problems in the prior art, the invention provides a method and device for document segmentation based on text lines. Whether or not text line units are merged into one paragraph is judged according to a merged score of the text line units; when the score of the text line units does not satisfy a merging need, merging of a current paragraph is ended, and processing of a new paragraph begins. According to the method and device for the document segmentation based on the text lines, the problems existing in the prior art can be solved simply and effectively; pages and document data structures can be extracted by using the method, and text line information is extracted from the document data structure corresponding to each text line; each document data structure including text lines is traversed in a full text, and context information of the full text and context information of each page can be calculated in a statistical mode according to a text line information list formed by the text line information of the document data structures separately; based on n text line unit structure lists in each page, by combining other context information, segmentation is conducted on the text line units in each page according to a segmentation algorithm.

Description

technical field [0001] The invention relates to the field of text processing, in particular to a text line-based document segmentation method and device. Background technique [0002] With the development of technology, more and more text processing relies on the automatic realization of machines, and among the existing document formats, there are PDF and PDF-like HTML documents, and the text in these documents is formed by lines instead of being directly merged For paragraphs, only through the visual style to ensure the effect of segmentation when people read. In order to allow the computer to automatically integrate the text lines in these documents into text paragraphs, so as to facilitate subsequent further processing of the text content in paragraph units, a feasible solution is proposed here. [0003] Most of the existing PDF and HTML text extractions directly output the extracted text line by line without segmentation; or perform segmentation based on the discovery o...
