Global Maps of Science based on the new Web-of-Science Categories
In August 2011, Thomson Reuters launched version 5 of the Science and Social
Science Citation Index in the Web of Science (WoS). Among other things, the 222
ISI Subject Categories (SCs) for these two databases in version 4 of WoS were
renamed and extended to 225 WoS Categories (WCs). A new set of 151 Subject
Categories (SCs) was added, but at a higher level of aggregation. Since we
previously used the ISI SCs as the baseline for a global map in Pajek (Rafols
et al., 2010) and brought this facility online (at
http://www.leydesdorff.net/overlaytoolkit), we recalibrated this map for the
new WC categories using the Journal Citation Reports 2010. In the new
installation, the base maps can also be made using VOSviewer (Van Eck &
Waltman, 2010).Comment: Scientometrics, in pres
Journal portfolio analysis for countries, cities, and organizations: maps and comparisons
Using Web of Science data, portfolio analysis in terms of journal coverage can be projected onto a base map for units of analysis such as countries, cities, universities, and firms. The units of analysis under study can be compared statistically across the 10,000+ journals. The interdisciplinarity of the portfolios is measured using Rao-Stirling diversity or Zhang et al.'s improved measure 2D3. At the country level we find regional differentiation (e.g., Latin American or Asian countries), but also a major divide between advanced and less-developed countries. Israel and Israeli cities outperform other nations and cities in terms of diversity. Universities appear to be specifically related to firms when a number of these units are exploratively compared. The instrument is relatively simple and straightforward, and one can generalize the application to any document set retrieved from the Web of Science (WoS).

Interdisciplinarity and research on local issues: evidence from a developing country
This paper explores the relationship between interdisciplinarity and research
pertaining to local issues. Using Colombian publications from 1991 until 2011
in the Web of Science, we investigate the relationship between the degree of
interdisciplinarity and the local orientation of the articles. We find that a
higher degree of interdisciplinarity in a publication is associated with a
greater emphasis on Colombian issues. In particular, our results suggest that
research that combines cognitively disparate disciplines, what we refer to as
distal interdisciplinarity, tends to be associated with more local focus of
research. We discuss the implications of these results in the context of
policies aiming to foster the local socio-economic impact of research in
developing countries.Comment: 24 page

Journal Maps, Interactive Overlays, and the Measurement of Interdisciplinarity on the Basis of Scopus Data (1996-2012)
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. The base maps can be
interactively overlaid with journal distributions in sets downloaded from
Scopus, for example, for the purpose of portfolio analysis. Rao-Stirling
diversity can be used as a measure of interdisciplinarity in the sets under
study. Maps at the global and the local level, however, can be very different
because of the different levels of aggregation involved. Two journals, for
example, can both belong to the humanities in the global map, but participate
in different specialty structures locally. The base map and interactive tools
are available online (with instructions) at
