Embodiment 1

[0040] Embodiment 1. A method for analyzing the content of an electronic invoice.

[0041] Combine below figure 1 The method of the first embodiment will be described in detail.

[0042] figure 1 It is a flow chart of the method for analyzing the content of the electronic invoice in Embodiment 1 of the present invention, such as figure 1 As shown, the electronic invoice described in the embodiment of the present invention is based on the layout file format, including a position analysis module, a text merging module and a text association identification module, including the following steps:

[0043] Step S101 , the location analysis module invokes the format file analysis engine module to perform location analysis on the content of the electronic invoice, and obtain a set of location information in units of characters.

[0044] Specifically, the location parsing module parses the location information of each character in the electronic invoice. Preferably in the embodimen...

Embodiment 2

[0063] Embodiment 2, the processing flow of the text merging module in the method for analyzing the content of the electronic invoice.

[0064] Combine below figure 2 The method of this embodiment will be described in detail.

[0065] figure 2 It is the processing flowchart of the text merging module in the method for analyzing the content of the electronic invoice in the second embodiment of the present invention, such as figure 2 As shown, the method of the present embodiment includes the following steps:

[0066] Step S201, sort the character sets in the position information set from top to bottom and from left to right.

[0067] Step S202 , using the character gap threshold to preliminarily merge characters in the same text field in the same line.

[0068] Step S203, using the tag dictionary to set the type attribute of each text field text line.

[0069] In the embodiment of the present invention, the tag dictionary defines the face elements of the electronic invo...

Abstract

The invention discloses an electronic invoice content analysis method and system, and belongs to the technical field of text content extraction. An electronic invoice is based on a layout file format. The system mainly comprises a position analysis module, a text combination module and a text associative identification module, wherein the position analysis module calls a layout file analysis engine module to perform position analysis on the content of the electronic invoice so as to obtain a position information set taking a character as a unit; the text combination module adopts inter-character gaps to combine characters belonging to same text regions so as to obtain a text region set; the text associative identification module performs associative identification of the text regions on the text region set in combination with a tag dictionary and text region gaps; and the analysis work of the whole electronic invoice is finished and analysis data is stored in a database. According to the method, the universality and adaptability of text content extraction can be effectively improved and the invoice content of different types and different styles can be analyzed.

Description

technical field [0001] The invention relates to the technical field of text content extraction, in particular to a method and system for analyzing content of an electronic invoice. Background technique [0002] In order to effectively save social resources, reduce tax costs, and finally realize paperless invoices, my country is stepping up efforts to promote electronic invoices. With the increasing attention and use of electronic invoices, the traditional invoice management system can no longer meet the requirements, and the electronic invoice management system came into being instead. Since the electronic invoice management system needs to store the content of the invoice, the analysis of the content of the electronic invoice is an essential step. However, due to the wide variety of invoices and complex styles, how to improve the generality and applicability of the invoice analysis method is an urgent problem to be solved. Contents of the invention [0003] In view of t...
