Paper duplication checking is a common work in universities and scientific research institutions, which is used to detect the repetition rate of papers and avoid academic misconduct. The process of repeated inspection usually includes the following steps:

Users upload papers: users upload their papers to the duplicate checking system.

Automatic duplicate checking by the system: 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.

Comparing with the resource database: The duplicate checking system will compare the papers uploaded by users with the compared documents in the resource database to 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.

Users can make targeted modifications according to the repeated parts in the duplicate checking report, so as to reduce the repetition rate of papers. At the same time, when re-checking papers, we should also pay attention to maintaining the accuracy and credibility of documents, and we should not fabricate data or sentences at will to reduce the repetition rate.

In addition, the duplicate checking websites such as HowNet and Wanfang are also commonly used duplicate checking tools, which have the advantages of simple operation, simple interface and stable system. However, it should be noted that the duplicate checking websites such as HowNet are generally not open to individuals, but only provided to relevant institutions, so students can only check in the library or some third-party duplicate checking websites. At the same time, we should also pay attention to choosing a regular duplicate checking website to avoid the risk of paper leakage caused by using an informal duplicate checking website.
