It should be noted that different schools and institutions may have different requirements for duplicate checking of papers, so it is best to know the specific requirements of schools or institutions before writing papers in order to better control the repetition rate of papers. In addition, different duplicate checking tools may calculate the duplicate checking rate of a paper in different ways, so when using different duplicate checking tools, different duplicate checking rates may be obtained for the same paper. Therefore, when selecting the duplicate checking tool, we also need to consider its reliability and accuracy.
