Abstract

The invention discloses a table data analysis method and device based on a PDF file, relates to the technical field of data processing, and mainly aims to improve the accuracy of a table data analysisresult in the PDF file. The method comprises the steps of obtaining lines and attribute information of the lines in a page, wherein the lines comprise transverse lines and vertical lines, and the attribute information of the lines comprises position information and length information; determining lines in the same table according to the attribute information of the lines, and marking the lines asgrouping lines; determining a table boundary corresponding to the grouped lines according to the attribute information of the lines in the grouped lines; according to the attribute information of themultiple lines in the grouping lines corresponding to the table, combining cells meeting preset conditions in the table, adding data information in the page into the corresponding cells in the table,wherein the table is composed of the cells, and the cells are composed of the lines. The method and the device are used for analyzing the table data in the PDF file.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a form data analysis method and device based on PDF files. Background technique [0002] With the continuous development of technology, the information on the network has exploded. In the field of data processing, since PDF (Portable Document Format, portable document format, PDF for short) files can be used in multiple systems, the use of such files in the field of data processing is becoming more and more frequent. Therefore, how to extract data from PDF files, especially tabular data, has been paid more and more attention by those skilled in the art. [0003] At present, in the field of data processing, when it is necessary to parse and extract form data in a PDF file, it is usually parsed from the PDF file to be parsed to get each constituent element and its related attribute information on each page, and then according to the above The corresponding html (H...
