For those who need to evaluate professional titles, it is very important to publish periodical papers. It is also necessary to check duplication before publishing a paper. Generally speaking, the duplicate checking rate of papers published by periodicals depends on the requirements of magazines or periodicals. If you want to know the duplicate checking rate of journals that need to be published, you can check the duplicate checking rules of published papers. If not, please refer to the following inspection range values:

1. The duplicate checking rate of ordinary (provincial or national) periodicals is between 25% and 30%.

2. The duplicate checking rate of core journals should generally be controlled within 5%- 10%.

2. What are the duplicate checking softwares for periodical papers?

Many authors will take the initiative to check the repetition of papers before submitting to magazines or periodicals, but in the face of complex duplicate checking software, authors are usually confused and don't know what duplicate checking software magazines or periodicals use to check the repetition rate of papers.

Generally speaking, papers published in magazines and periodicals need to be checked by the content checking system. The internal detection systems of journals are mainly divided into academic misconduct document detection system (AMLC) for sci-tech journals and academic misconduct document detection system (SMLC) for social science journals, and the covered databases and articles are quite different.

If these two duplicate checking systems are used for detection, the author must choose the appropriate duplicate checking system to detect the papers to be published according to whether his articles are sci-tech journals or social science journals.

Paperfree and papertime are also used by many people to test the first and middle drafts of their papers because of their price advantages. However, we need to remind everyone that we must know what kind of paper detection system is used in magazines or periodicals before submitting. After it is finalized, it must be tested by the system specified by the magazine.
