First, check the authority of the software.
If the duplicate checking software is not authoritative, its duplicate checking accuracy will drop. For example, when you check, it is not only a data, but also meets the requirements of the school. But when you submit your paper to the school, the school will have to recheck it and finally get another data, which can't meet the requirements of the school. So when we are looking for duplicate checking software, we must evaluate the most authoritative software from multiple duplicate checking software. Security is also important.
Second, try to use the same duplicate checking software as the school.
The results are also the most similar when testing the same repeated inspection system. Therefore, in order to avoid inconsistent duplicate checking results caused by different systems, it is recommended that you use duplicate checking software consistent with the school to avoid excessive data discrepancy.
