SJR (SCImago Journal & Country Rank)
The SJR also will create maps or bubble charts based on a subject citation relationship.
What is SJR?
Developed by Professor Félix de Moya, Research Professor at Consejo Superior de Investigaciones Científicas, SCImago Journal Rank is a prestige metric based on the idea that ‘all citations are not created equal’. With SJR, the subject field, quality and reputation of the journal has a direct effect on the value of a citation. The SJR
- Is weighted by the prestige of the journal, thereby ‘leveling the playing field’ among journals
- Eliminates manipulation: raise the SJR ranking by being published in more reputable journals
- ‘Shares’ a journal’s prestige equally over the total number of citations in that journal
- Normalizes for differences in citation behavior between subject fields
SJR uses Elsevier (Scopus) citation data.
