SCImago Journal Rank
- SCImago Journal Rank (SJR) is a measure of the prestige of scholarly journals based on citations and the prestige of the journals where the citations come from.
- SJR assigns different values to citations depending on the perceived prestige of the journals where they come from.
- Studies have found that reliability of published research works may be decreasing with increasing journal rank.
- The calculation of SJR is similar to the Eigenfactor score but is based on the Scopus database.
- SJR is developed by the Scimago Lab and is a variant of the eigenvector centrality measure used in network theory.
- The SJR indicator is a size-independent indicator that can be used for journal comparisons in science evaluation processes.
- SJR is a free journal metric inspired by and using an algorithm similar to PageRank.
- The SJR algorithm begins by setting an identical amount of prestige to each journal and redistributes it through citations until a steady-state solution is reached.
