Introduction SJR SNIP powered by Scopus

SJR & SNIP - a new perspective in Journal Metrics. This short video explains how SCImago Journal Rank (SJR) and Source Normalized Impact per Paper (SNIP) are calculated. SJR and SNIP are considering in which context in which a Journal is performing looking at differences in research areas with different citation behaviours.
The metrics will be refreshed twice a year and cover more nearly 18,000 Journals with peer-reviewed content such as , journals, proceedings, and book series - not trade journals. In other words, all the active peer reviewed source-types will have metrics. In addition, only the peer reviewed content within these peer reviewed sources (articles, reviews and conference papers) is used to generate the metrics.

It would be interesting to see a presentation where Snip and SJR are calculated for a journal such as Nature, for which impact factor, SNIP and some other derivated indicators can be easily calculated, while SJR seems to show a certain lack of transparency in its calculation and validation. A lot of discussion over IF and SNIP can be found in the scientific literature, but ¿Is SJR validated and transparent enough to be used by policymakers? A presentation with the calculus for Nature would help.
