Paper duplication checking is carried out by comparing the similarity between the content of the paper and the existing text in a huge database. The specific steps are as follows:

Choose a reliable duplicate checking system: choose a reliable duplicate checking system, such as HowNet, VIP, Wanfang, paperFree and papertime of the paper series. These systems will have a huge database, including a large number of published documents and Internet content, which can ensure the accuracy and reliability of duplicate checking.

Upload paper: After selecting the duplicate checking system, you need to upload the paper to the system. Different systems may upload in different ways, which can generally be operated through web pages or clients.

Waiting for duplicate checking results: after the paper is uploaded, you need to wait for the system to check duplicates. This process may take some time, and the specific time varies with different duplicate checking systems and different paper lengths.

View duplicate check report: After duplicate check is completed, you can download duplicate check report. The report contains similar contents and comparison results as those in the database, as well as corresponding modification suggestions and similarity analysis.

Revise according to the report: According to the duplicate checking report, the paper needs to be revised and optimized. If there is a part with high similarity, it needs to be modified or quoted.

Re-check: After revising the paper, you need to check it again. If the similarity is still high, you may need to modify the optimization again until you meet the requirements.

Check duplicate strictly according to the requirements of the school: different schools or institutions may have different standards for duplicate checking and summation, so we must check duplicate according to the requirements of the school or institution and pay attention to abide by relevant regulations and requirements.
