Secondly, the results of duplicate checking by third-party testing institutions are also influenced by the originality of the paper and the creative environment. If a paper refers to a large number of documents in the process of creation, and makes sufficient writing norms in citation and annotation, then its similarity may be high. But this does not mean that there is plagiarism in this article, but that the author has made reasonable quotations and references. Therefore, when evaluating the results of duplicate checking, we should comprehensively consider the citation and annotation of the paper.
Thirdly, the results of duplicate checking by third-party testing institutions may also be limited by the database. When the duplicate check result of a paper is high, we should not only consider whether there is plagiarism, but also consider whether there are similar documents in the database. If the database contains references to this paper or commonly used phrases and concepts in this field, the similarity of this paper may be overestimated.
To sum up, the results of duplicate checking of papers by third-party testing institutions can reflect the similarity of papers to a certain extent, but it does not fully represent whether there is plagiarism in papers. When evaluating the duplicate checking results of papers, we should comprehensively consider the citation and annotation of papers and the limitations of the database. In addition, in order to ensure the originality of the paper, the author should strictly abide by academic norms and reasonably quote other people's research results to avoid being misjudged as plagiarism.
