 The "SJR indicator" assigns different values to citations depending on the importance of the journals where they come from.This way, citations coming from highly important journals will be more valuable and hence will provide more prestige to the journals receiving them.The calculation of the "SJR indicator" is similar to the "Eigenfactor score", with the former being based on the Scopus database and the latter on the Web of Science database, and there are other differences.
