The SCImago Institutions Rankings (SIR) World Reports publish annually an international ranking of more than 2000 research institutions and organizations. The reports list indicator values based on publication and citation data from Scopus (Elsevier) for research-devoted institutions with at least 100 papers published within one year. The second edition published in 2010 included for each insti...

Impact factors (and similar measures such as the Scimago Journal Rankings) suffer from two problems: (i) citation behavior varies among fields of science and therefore leads to systematic differences, and (ii) there are no statistics to inform us whether differences are significant. The recently introduced SNIP indicator of Scopus tries to remedy the first of these two problems, but a number of...

Governments sometimes need to analyse sets of research papers within a field in order to monitor progress, assess the effect of recent policy changes, or identify areas of excellence. They may compare the average citation impacts of the papers by dividing them by the world average for the field and year. Since citation data is highly skewed, however, simple averages may be too imprecise to robu...

A dataset containing 111,616 documents in astronomy and astrophysics has been created and is being partitioned by several research groups using different algorithms. In this paper, rather than partitioning the dataset directly, we locate the data in a previously created model in which the full Scopus database was partitioned. Given that the other research groups are partitioning the data direct...

BACKGROUND We conducted a comprehensive bibliometrics analysis to calculate the H, G, M, A and R indicators for all Iranian biomedical research centers (IBRCs) from the output of ISI Web of Science (WoS) and Scopus between 1991 and 2010. We compared the research performance of the research centers according to these indicators. METHODS This was a cross-sectional and descriptive-analytical stu...
