Paper check, the full name of paper check, is a paper originality detection method, which refers to the comparison of written papers with major discussion libraries through the comparison of paper detection system resource libraries. In short, it is to test the plagiarism rate and see if your paper is original.

The school uses the paper duplicate checking system to check the duplicate of college students' papers, mainly recording the repetition rate of each college student's paper, so as to see whether the repetition rate of students' papers meets the school standards. Students can check the copy of the paper in advance. After uploading the paper to the duplicate checking system of HowNet, they can get a duplicate checking report after waiting for about half an hour to an hour. Finally, according to the information in the report, the repetition part of the paper is revised to ensure that the repetition rate of the revised paper is within the requirements of the school.
