CiteScore is a family of eight indicators that offer complementary views to analyze the publication influence of serial titles of interest. Derived from the Scopus database, CiteScore metrics offer a more transparent, current, comprehensive and accurate indication of a serial’s impact.
SNIP (Source Normalized Impact per Paper) Measures contextual citation impact by weighting citations based on the total number of citations in a subject field. The impact of a single citation is given higher value in subject areas where citations are less likely, and vice versa.
SJR (SCImago Journal Rank): Based on the concept of a transfer of prestige between journals via their citation links. Drawing on a similar approach to the Google PageRank algorithm - which assumes that important websites are linked to from other important websites - SJR weights each incoming citation to a journal by the SJR of the citing journal, with a citation from a high-SJR source counting for more than a citation from a low-SJR source.
