1, influencing factors:
The impact factors of periodicals are the core basis of JCR zoning. Generally speaking, the higher the impact factor, the greater the academic status and influence of the journal. According to the impact factors, JCR divides journals into four grades: Q 1, Q2, Q3 and Q4.
2. Subject category:
The JCR department will also consider the subject category of the journal. There may be great differences between journals in different disciplines, so it is more reasonable to divide journals into the same discipline category.
3, cited half-life:
JCR will also consider the citation half-life of periodicals when dividing regions. The citation half-life refers to the time when the paper is published and the number of citations is reduced by half. The long citation half-life indicates that the influence of periodicals is lasting.
4. Number of papers published:
When JCR divides regions, it will consider the number of papers published in journals. Journals with a large number of published papers may have high impact factors, but other factors need to be considered comprehensively when zoning.
JCR zoning refers to dividing journals into different grades or regions according to their influence and citation frequency. This zoning system aims to help scholars and researchers evaluate the quality and importance of journals, so as to better choose the appropriate journals to publish their research results.
Journals are divided into four main regions by JCR zoning system: ScienceCitationIndex, in which SCI and SSCI are the most famous and important regions, covering top journals of various disciplines.
JCR zoning is very important for scholars and researchers. First of all, it can help them choose appropriate journals to publish their research results and improve the popularity and influence of the papers. Secondly, JCR zoning is also one of the important indicators to evaluate the performance of scholars and research institutions.
Many universities and scientific research institutions will evaluate the academic level and research ability of researchers according to the number of published papers and influencing factors, which also limits the application scope of the system.
