What is the Journal Analyzer
SJR (SCImago Journal Rank)
SJR is weighted by the prestige of a journal Subject field, quality, and reputation of the journal have a direct effect on the value of a citation.
SJR assigns relative scores to all of the sources in a citation network. Its methodology is inspired by the Google PageRank algorithm, in that not all citations are equal. A source transfers its own 'prestige', or status, to another source through the act of citing it. A citation from a source with a relatively high SJR is worth more than a citation from a source with a lower SJR.
SNIP (Source Normalized Impact per Paper)
SNIP measures a source’s contextual citation impact by weighting citations based on the total number of citations in a subject field. It helps you make a direct comparison of sources in different subject fields.
SNIP takes into account characteristics of the source's subject field, which is the set of documents citing that source. SNIP especially considers
- the frequency at which authors cite other papers in their reference lists
- the speed at which citation impact matures
- the extent to which the database used in the assessment covers the field’s literature
