The grid-based duplicate checking system will divide the paper into sections and clauses according to certain algorithms and comparison techniques, and extract the divided content and compare it with the content in the system's own literature collection. If obvious plagiarism is found, it will be marked with obvious color. Finally, the results will be obtained according to the repetition rate calculation formula and displayed in the generated test report.
It should be noted that the algorithms and databases of different duplicate checking systems are different, so the duplicate checking results will be different. For the first draft of the paper, it is suggested that free duplicate checking software such as paperfree, papertime and paperday can be used. And for the final draft, use the duplicate checking system required by the school to ensure that the paper meets the requirements of academic norms.
