The evaluation of the paper should not only look at the results of duplicate checking, but also consider other factors. Duplicate checking is only an index to evaluate the originality of a paper and a means to judge whether the paper is plagiarized. Besides duplicate checking, other factors such as innovation, academic value, logicality and language expression should be considered in the evaluation of papers. Different evaluation institutions and judges may have different evaluation criteria and weight distribution, but generally speaking, the results of duplicate checking have a great influence on the evaluation of papers. If the duplicate check result of the paper is too high, it may be considered plagiarism, which will affect the evaluation result of the paper. However, just checking the results does not necessarily ensure that the paper passes the appraisal, and other factors need to be considered comprehensively, such as the academic value, innovation and logic of the paper. Therefore, when writing a paper, we should seriously abide by the academic integrity norms, pay attention to the originality and quality of the paper, and at the same time make full preparations, participate in the paper review, and strive for good results.
