Some fields, particularly those in the life sciences, tend to conform to this citation pattern better than others, leading to some widely recognized distortions.”
From article: “Prestige measured by quantity of citations is one thing, but when it is based on the quality of those citations, you get a better sense of the real value of research to a community. Research Trends talks to Prof. Félix de Moya about SCImago Journal Rank (SJR), which ranks journals based on where their citations originate.”
From article :Bibliometric indicators are not without their own controversies (1, 2) and recently there has been an explosion of new metrics, accompanying a shift in the mindset of the scientific community towards a multidimensional view of journal evaluation.”
Elsevier’s Scopus Partners with CWTS and SCImago to Offer Multidimensional Evaluation of Research Journals
From press release: “Elsevier… announced that its flagship product Scopus has successfully partnered with the Centre for Science and Technology Studies (CWTS) and the SCImago Research Group, endorsing two complementary journal metrics, SNIP and SJR. The metrics will be freely available online at www.journalmetrics.com, and integrated into Scopus, allowing researchers around the world to analyze journals within the abstract and citation database. The indicators will offer a greater currency and flexibility in journal performance measurement than any single-metric method currently available.”

“How do SJR and SNIP compare to the Impact Factor? They offer new perspectives in Journal Evaluation that look at the context in which a journal is performing and normalize for citation behaviour. Find more information at www.journalmetrics.com”
Video
“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. “
Looks like an interesting introductory course to the various concepts of scientific publishing and Science 2.0. (found because it linked to my Identity 2.0 post)
