Many people will double-check their papers for better revision, but after double-checking, they find that the results are different. What is the reason?

1. The database of the file duplicate checking system is constantly updated.

The reason why the paper duplication checking system can detect the repetition rate lies in the database contained in the system. Only with the database can we compare the contents of submitted papers, so as to detect the repeated parts in the papers and calculate the repetition rate. The resources on the Internet and related academic resources have been constantly updated and changed. At the same time, the database resources in the paper duplicate checking system have also been updated and included. If there is plagiarism in the paper, but this part has not been included in the system when the paper is checked for duplication for the first time, then the duplication cannot be detected, and then the system update may be included, so there will be different repetition rates when the paper is checked for duplication for the second time.

2, self-built library content repeated inspection

What we need to pay attention to is that if our excerpts are not included in the system, then the previous tests can't find duplicates. If you know that it is plagiarism, you will worry that the school will notice it when it checks again, so it is suggested to modify this part. Now many schools will have their own libraries, so the results will be different.

3. Paper uploading mode

There are two ways to upload papers: copy and paste and document upload. If you upload a paper by copying and pasting, some paper formats may be eliminated by the former, so the system may recognize some parts that will not be detected as text duplicate checking, and thus include them in the scope of duplicate checking. There are many formats for uploading documents, such as pdf, word, etc. However, it is recommended that you use word to submit the document, so that the test results are more accurate.
