The duplicate checking rate of papers refers to the repeated contents in papers, including repeated paragraphs, sentences, words, formats, etc. The duplicate checking system will compare and analyze the test papers according to a certain algorithm, so as to calculate the repetition rate of the test papers.

In the process of duplicate checking, the duplicate checking system will detect the similarity of test papers according to the criterion that 13 characters will be judged as duplicates. If there are many academic misconduct such as plagiarism in the paper, it will be detected by the duplicate checking system and the corresponding repetition rate will be calculated. In addition, the duplicate checking system will also check the citation source, format problems, pictures and tables, language problems, etc. in the paper to ensure the standardization and legitimacy of the paper.

Different duplicate checking systems are different from the specific regulations of universities and periodicals, so it is best to use a duplicate checking system consistent with universities or periodicals to ensure the accuracy of the results. At the same time, we should also pay attention to the proper citation and annotation of the paper to avoid being misjudged as plagiarism.
