It will be different.
Why are the duplicate checking results of the two papers different?
1. Paper duplicate checking system has a certain detection threshold.
Maybe many students don't know the meaning of the threshold. For example, if the duplicate checking system of a paper is set within 1 thousand words, if it is similar to others within 100 words, it is not judged as plagiarism. In fact, this threshold is set at 10%. If the word 1 10 is similar, it will be judged as a duplicate, and the threshold setting of each system is different, so you should modify it according to the report and re-check. If there is a new repetition, then it is not difficult to understand.
2. Update the database of the paper duplicate checking system.
Every day, a large amount of content is published on the Internet, and a large number of academic documents are published. The paper duplicate inspection system constantly updates resources. So when you check the repetition again, the content that was not detected before may be repeated for the second time, which will also lead to different results of repetition rate.
3. The transformation is not in place
When we modify the paper, if we don't modify the repeated contents in place, for example, some key contents of the repeated part have not changed, then the duplicate checking system of the paper can still detect the duplicates that are roughly similar to the original part. Therefore, if we don't add some original content better in the process of revising the paper, but use others' content for reference to make a small-scale revision again, it will also lead to the failure of reducing the repetition rate. Inconsistency between two duplicate checks is a common problem in duplicate checks.
The reason why this happens is that different brands of papers, different data detected by the system and different algorithms of the detection system make different websites have different repetition rates.
