Thesis library is not covered: some papers may not be covered by the duplicate checking system, which may be because the database used by the system is small or the publishing institution of the paper has not submitted the papers to the duplicate checking system.
Content of the paper: If the content of the paper is too simple or the quality is not high, it may be ignored by the duplicate checking system or cannot be accurately compared.
Problems with the duplicate checking system: Sometimes the duplicate checking system may fail or make mistakes, which makes it impossible to compare and identify the contents of the paper correctly. You can use papertime to check the weight, and the detection is more accurate.
In addition, if you don't submit or enter key information related to the error, such as title and author, it will also lead to duplicate checking failure. Therefore, when checking the duplicate of undergraduate thesis, we need to pay attention to the above problems to ensure that the thesis can be correctly detected and processed.
