Paper duplication checking is to check whether there is plagiarism or other academic misconduct by comparing the papers uploaded by users with the documents in the duplication checking system. Check the duplicate checking systems commonly used in universities and academic institutions, such as HowNet, VIP, PaperFree, papertime, etc. , to determine whether there are contents highly similar to other documents in the paper, and the proportion of these contents in the total text reproduction ratio.

Specific duplicate checking steps are as follows:

1 User uploads papers: the user uploads the papers that need to be checked to the duplicate checking system.

2. Automatic duplicate checking: The duplicate checking system will perform segmentation detection according to the title, keywords, text and other contents of the paper, and record the repetition rate.

3. Comparing the resource database: The duplicate checking system will compare the papers uploaded by users with the comparison documents in the resource database, and establish a fingerprint index.

Test results: The duplicate checking system will calculate the overall duplicate checking rate of the paper according to the comparison results and feed back the results to users. Finally, users can make targeted amendments according to the repeated parts in the duplicate checking report to reduce the repetition rate of the paper. Check the copy of the paper.
