Embodiment 1

[0032] A full-text difference comparison method, comprising the steps of:

[0033] see figure 1 , in this embodiment, take comparing the contract documents, uploading the original document in word format and the comparison document in PDF format as an example. A full-text difference comparison method, comprising the following steps: the comparison document and the original document are recognized by an OCR recognition engine to generate a recognized text, the recognized text includes the recognized text in the text, and the coordinates of each text in the corresponding OCR recognized image information; identify the text and compare the difference text through the text comparison algorithm, and obtain the coordinates of the difference text; locate the difference text according to the coordinates of the difference text, and then mark the difference text in the comparison file, such as image 3 shown. The comparison results are generally saved through the database. The text in...

Embodiment 2

[0041] see figure 1 and Figure 5 , a full-text difference comparison device, comprising a background server, the background server is provided with a memory and a processor, the memory is stored with instructions, and the instructions are suitable for being loaded by the processor and performing the following steps:

[0042] The comparison document and the original document recognize the text through the OCR recognition engine and generate a recognized text, which includes the text in the recognized text and the coordinate information of each text in the corresponding OCR recognition image; the text comparison algorithm is used to compare the recognized text to find out the difference text , to obtain the coordinates of the difference text; locate the difference text, and then mark the difference text in the comparison file, such as image 3 shown. The text includes Chinese characters, English letters, numbers, and symbols but is not limited thereto. Generally, the backgro...

Abstract

The invention relates to a full-text difference comparison method, comprising the following steps: a comparison part and an original part recognize characters through an OCR recognition engine and generate recognition text, wherein the recognition text contains coordinates corresponding to each character; Text recognition adopts text comparison algorithm to compare the difference characters and obtain the coordinates of the difference characters. the difference text is located and the difference text is marked in the contrast. The invention also relates to a full-text difference alignment device. The invention combines the OCR intelligent recognition and the text comparison algorithm, quickly compares the difference characters, locates and marks the difference characters according to the coordinates, greatly improves the efficiency and the comparison accuracy rate; 2, the system can recognize the file format and can convert the text format to the image format image, therefore, it is suitable for the difference comparison of various file formats, and the application range is wide.

Description

technical field [0001] The invention relates to a full-text difference comparison method, which belongs to the field of intelligent identification and comparison. Background technique [0002] In the existing technology, in order to verify the authenticity of the document, it is necessary to compare the document with its corresponding original. For example, in the contract review, the contract text is large, and there is a need for full-text verification. The comparison method is generally through manual naked eye review and comparison. When the amount of documents to be compared is large, it not only takes a long time, but also has high labor costs and a high risk of error. [0003] The publication number is: CN106372040A, and the invention patent titled "Smart Substation Configuration File Difference Comparison System" discloses a smart substation configuration file difference comparison method: Step 1. The document data comparison module first converts each file into Cor...
