Paper duplication checking is usually a kind of auditing system adopted by domestic universities or journals to conduct original review of upcoming papers or graduation papers and to combat academic misconduct that may occur in the process of academic paper creation. Paper duplication checking is generally based on a certain scientific and strict identification rule algorithm, to detect the repeated content in the paper, and finally to calculate the proportion of repeated words in the paper to the total number of words in the paper, that is, to calculate the duplication checking rate of the paper.

Generally, universities and magazines will not explicitly stipulate that duplicate checking is not allowed in advance, but they will give a duplicate checking standard and paper format, and write and check copies of papers according to the specified requirements. If the results of duplicate checking rate meet the requirements of universities or magazines, then the chances of successful publication of the submitted papers are greater, and the graduation thesis can also be qualified for thesis defense, so as to graduate smoothly.
