The present invention provides a method for identifying contract elements of a PDF file, comprising: reading the text blocks of the PDF file according to a preset reading method, and storing key information of each text block; wherein, the key information includes page number, text content and coordinates; according to the coordinates of the text blocks in the same page number, the text blocks of the same line are obtained, and the text blocks of the same line and the text blocks of two adjacent lines are divided into sentences; each sentence is identified according to the characteristics of the clause and the title , to identify the corresponding clauses and titles, and form the contract content according to the identified sentences; match the contract content with at least one contract template, and identify the contract content according to the matched contract module, so as to identify the contract elements. The beneficial effect of the present invention is to realize the formation of natural sentences from scattered and complex PDF text blocks; and to identify the contract content according to the matched contract modules, thereby improving the accuracy of identifying contract elements.
Description
Technical field[0001]The present invention relates to the field of information technology, in particular to a method for identifying contract elements of PDF files.Background technique[0002]In many contracts, the format of the contract is chaotic and there is no hierarchical relationship. The content of the contract appears to be the main text throughout, without structured data display. The business needs to disassemble the contract to identify different levels of titles, contract statement content, 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 schemes for automatically identifying contract content are currently provided, but the above schemes 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-mentioned problems in the p...
