Abstract. In this study we present an application which can be accessed via www.excellence-networks.net and which represents networks of scientific institutions worldwide. The application is based on papers (articles, reviews and conference papers) published between 2007 and 2011. It uses (network) data, on which the SCImago Institutions Ranking is based (Scopus data from Elsevier).

Abstract. A bibliometric analysis of research production in scientific journals, of the Scopus subject category Food Science, between 2003 and 2013, from seventy-one Spanish institutions with at least fifty works published, is presented. Statistical z tests are used for an evaluation of the degree to which an observed number of top-cited papers (top-10%) for an institution differs from the number expected, on the basis of randomness in the selection of papers.

Abstract. Ten bibliometric indicators were used to assess European publishing intensity in journals listed in Scopus under the subject category “Library and Information Science” between 2003 and 2012. The findings were analyzed for the 20 countries and 25 research institutions with the greatest output in that period. The indicators calculated included normalized impact, number and proportion of highly cited papers and the distribution of papers by the quartiles defined in the Scimago Journal Rank (SJR).

Abstract. Using Scopus data, we construct a global map of science based on aggregated journal–journal citations from 1996–2012 (N of journals = 20,554). This base map enables users to overlay downloads from Scopus interactively. Using a single year (e.g., 2012), results can be compared with mappings based on the Journal Citation Reports at the Web of Science (N = 10,936). The Scopus maps are more detailed at both the local and global levels because of their greater coverage, including, for example, the arts and humanities.

Abstract

Abstract. A graphical interface designed to access the bibliometric indicators database of the SCImago Journal & Country Rank portal (http://scimagojr.com/shapeofscience) is described. The map was generated from the relational matrix based on the citation, co-citation, and bibliographic coupling formed by the nearly 20,000 publications (journals and conference proceedings) registered in Scopus. The map layout is based on a variant of a force-directed algorithm using Noacks proposal of an edge-repulsion energy model.

Resumen. Se analiza la investigación española en células madre en el Science Citation Index (SCI) entre 1997 y 2010 con una división temporal en tres sub-perí­odos, mediante técnicas de visualización basadas en redes sociales. Se han utilizado los descriptores KeyWords Plus (KW+) como unidad de análisis, su coocurrencia como unidad de medida, y Pajek y VOSviewer como herramientas para la generación y visualización de redes sociales.

Abstract
Purpose
The purpose of this paper is to visualize the structure of SCImago Journal & Country Rank (SJR) coverage of the extensive citation network of Scopus journals, examining this bibliometric portal through an alternative approach, applying clustering and visualization techniques to a combination of citation-based links.

Abstract. This paper presents a comparative benchmarking of scientometric indicators to characterize the patterns of publication and research performance at the country level, in a specific field (nanoscience and nanotechnology) during the period 2003–2013. The aim was to assess how decisive collaboration may be in attaining a sound level of scientific performance, and how important leadership is for publication.

Abstract. Cuba has developed a biopharmaceutical sector that involves some of the country’s most relevant scientific institutions. Despite the severe constraints on resources resulting from the U.S. embargo, the results achieved by this sector have contributed to put the country’s health indicators at the same level of high-income nations.
