Submission detection: students submit their papers to the duplicate checking system of the school, and the system will scan the full text of the papers.

Systematic comparison: the system compares the paper with the files in the database. The method of comparison is usually to judge whether there are duplicate parts by counting the number of the same words or phrases appearing in the literature.

Generate duplicate checking report: the system will generate duplicate checking report, including similarity score of papers and detailed duplicate checking contents.

Revise and improve: students can revise and improve the paper according to the information in the duplicate check report to avoid plagiarism and repetition.

Different duplicate checking systems may use different algorithms and databases, so the duplicate checking reports generated may be different. In addition, schools have different requirements for the proportion of repeated parts of papers.
