Different educational background, majors and colleges may have different requirements on the duplicate checking rate of papers, but generally speaking, the duplicate checking rate of undergraduate graduation papers is less than 30%, and that of master's and doctoral dissertations should be less than 10%~ 15%.

The duplicate checking system should try its best to ensure the accuracy of detection, and can detect all similar works, including similar works, changed sentences, increased fallacies, etc. , rather than just finding complete agreement or similarity.

The duplicate checking system also needs to have a faster speed, improve efficiency and facilitate scholars to finish their work better.

The system should be easy to use and operate. Scholars don't need too much technical background, just follow the system prompts.

The papers tested are the fruits of scholars' labor, and their privacy should be protected. When testing, it should ensure that its papers are not leaked and its interests are protected.

The scope of duplicate checking should be clear, including quotation and translation content, to avoid misjudgment. At the same time, we should fully consider the particularity between different disciplines and formulate duplicate checking standards for different disciplines.

The test results should be output in the form of a report, clearly showing the test results, test time, test source and other detailed information, so that scholars can better understand the situation of the paper and make necessary revisions. In addition, the re-inspection report should also be kept for future reference.

In short, when writing a paper, you need to be original and avoid plagiarism and repetition. At the same time, we need to pay attention to the requirements and standards of duplicate checking, and write and test according to the prescribed standards.
