SCImago Journal Rank
Adopting this view, the SJR indicator assigns different values to citations depending on the perceived prestige of the journals where they come from.SJR is developed by the Scimago Lab,[5] originated from a research group at the University of Granada.The SJR indicator has been developed to be used in extremely large and heterogeneous journal citation networks.The SJR indicator is a free journal metric inspired by, and using an algorithm similar to, PageRank.The SJR indicator computation is carried out using an iterative algorithm that distributes prestige values among the journals until a steady-state solution is reached.
