Re-examination of papers refers to checking the repetition rate of papers. We all know that writing a paper requires reading and referring to a large number of documents to help us organize our own content. Because of this, it is inevitable that some contents overlap in the article. Re-examining the paper is to help us avoid the phenomenon of high repetition rate caused by improper citation. But for some students, the re-examination of papers makes people love and hate each other. If the re-examination fails, the paper will be rejected, leading to graduation failure.
