There are a large number of articles in Sci journals, and the cost is particularly high. Basically, it can be paid with money. These journals are predatory journals with low academic value and may be eliminated by sci. Therefore, some early warnings of such journals are called international journal early warnings.
The partition table of the Document Information Center of the Chinese Academy of Sciences released the news at the first time, saying that an "early warning list of international journals" would be launched, and the specific list would be determined by combining qualitative and quantitative methods. "Qualitative" is based on expert evaluation and word of mouth, which has great uncertainty. "Quantitative" clearly points out the comprehensive evaluation based on the number of articles published in the journal, the internationalization degree of the author, the rejection rate, the paper processing fee, the journal transcendence index, the self-citation rate and the rejection information.
