Test content: The duplicate checking system will check all parts of the paper, including title, abstract, text, references and so on. , in which the text part usually accounts for a large proportion.

Detection scope: usually only the cited part of the paper is detected, and the content outside the citation is not detected. However, some schools will require all the contents of the test paper to be tested.

Detection rate: general schools will stipulate that the duplicate checking rate is below 20% as qualified. If the duplicate checking rate exceeds this ratio, it is necessary to revise the paper and check it again.

Detection algorithm: most duplicate checking systems use fuzzy algorithm, that is, divide the test paper into blocks, then calculate the similarity between each block and other test papers, and finally get the total duplicate checking rate.

It should be noted that different schools may have different standards and requirements for duplicate checking of undergraduate graduation thesis, and the specific situation needs to be carefully checked according to the relevant regulations of the school.
