Abstract

The invention provides a method for identifying contract elements of a PDF file. The method comprises the following steps: reading text blocks of a PDF file according to a preset reading mode, and storing key information of each text block; wherein the key information comprises a page number, text content and coordinates; obtaining character blocks in the same row according to the coordinates of the character blocks in the same page number, and performing statement division on the character blocks in the same row and the adjacent two rows of character blocks; identifying each statement according to the term characteristics and the title characteristics to obtain corresponding terms and titles, and forming contract content according to the identified statements; and matching the contract content with at least one contract template, and identifying the contract content according to the contract module obtained by matching so as to identify contract elements. The method has the beneficialeffects that scattered and complex PDF text blocks form natural statements; and the contract content is identified according to the contract module obtained by matching, so that the accuracy of identifying the contract elements is improved.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method for identifying contract elements of a PDF file. Background technique [0002] In many contracts, the format of the contract is chaotic and there is no hierarchical relationship. The content of the contract seems to be the text throughout, and there is no structured data display. Businesses need to disassemble contracts and identify different levels of titles, contract declarations, and contract terms. Currently, each item can be marked manually, which is inefficient, takes a long time, and consumes a lot of resources. [0003] Based on this, a variety of solutions for automatically identifying contract content are currently provided, but the above solutions are basically applied to Word files, and there is currently a lack of a method for automatically identifying contract elements in PDF files. SUMMARY OF THE INVENTION [0004] In view of the above problems ex...
