Abstract

The invention belongs to the field of document application and discloses a method for identifying data form in document and a device thereof. The method includes that: text in PDF document is extracted; the text is divided according to the attribute of the extracted text, thus obtaining a division result; the division result is judged and processed, and identification is carried out, thus generating a data form; the data form is stored into an independent intermediate data structure; and the data form in the intermediate data structure is restored according to target document format. In the invention, data form in PDF is accurately converted, editability after conversion is greatly improved, and manual processing on document after conversion is reduced.

Description

technical field [0001] The invention belongs to the field of document application, and in particular relates to a method and device for identifying data tables in a document. Background technique [0002] With the continuous popularization of computers, paperless office has been more and more applied, and a large number of various documents have also appeared in front of users. [0003] In a Portable Document Format (PDF) document, the table actually seen is formed by superimposing lines and text. Therefore, when converting a PDF file to other document formats that are easier to edit, if you only extract the original data content from the PDF document, you will get scattered text content and lines; if you need a table, you need to manually delete the lines and insert the table , and refilling the text content into the form is time-consuming and labor-intensive. [0004] At the same time, in the PDF, some text content is presented in a form similar to a table, but there is ...

Therefore, when converting a PDF file to other document formats that are easier to edit, if you only extract the original data content from the PDF document, you will get scattered text content and lines; if you need a table, you need to manually delete the lines and insert the table , and refill the text content into the form, which is time-consuming and laborious

[0004] At the same time, in the PDF, there are still some text contents that are presented in a form similar to a table, but there is no corresponding table line to form a real table

After the text content is extracted, it is difficult to maintain the original typesetting without special processing

[0005] After extracting the data from the PDF documen
