Many students will copy other people's works when writing their papers, and the whole paper lacks their own unique opinions, which will lead to academic misconduct. In order to improve students' personal knowledge and ability, duplicate checking in colleges and universities has become a necessary means to maintain sound academic development. Therefore, this is also the reason why the graduation thesis should be repeated. To put it bluntly, it is to prevent students from academic fraud and plagiarism, encourage students to be original, and take measures to ensure students to create their own unique opinions.

Paper duplication checking is to upload the author's paper content to the paper duplication checking system, and then compare it with the data content in the database. When the graduation thesis is similar or repeated with some contents in the database, the duplicate checking system will mark the graduation thesis at this time. When the marked content of the paper reaches a certain proportion, it shows that the paper has a high repetition rate and is suspected of plagiarism. When the content marked is less, it means that your paper is original.
