The repetition rate of general periodical papers is generally less than 25%, and some slightly strict periodicals are less than 20%.
The repetition rate of core journals is relatively strict, generally within 5%- 15%, and some Chinese core journals even require that the repetition rate should not exceed 10%.
It should be noted that each journal has a repetition rate threshold in each span. For the requirements of core journals, the inspection rate of 5%- 10% is only a reference threshold, and the specific requirements need to be subject to the journal requirements.
The repetition rate can be determined by paperless inspection.
