Aggregated Journal–Journal Citation Relations in Scopus and Web of Science Matched and Compared in Terms of Networks, Maps, and Interactive Overlays
Open accessAbstract
We compare the network of aggregated journal–journal citation relations provided by the J ournal C itation R eports (JCR) 2012 of the Science Citation Index (SCI) and S ocial S ciences C itation I ndex (SSCI) with similar data based on S copus 2012. First, global and overlay maps were developed for the 2 sets separately. Using fuzzy‐string matching and ISSN numbers, we were able to match 10,524 journal names between the 2 sets: 96.4% of the 10,936 journals contained in JCR, or 51.2% of the 20,554 journals covered by S copus. Network analysis was pursued on the set of journals shared between the 2 databases and the 2 sets of unique journals. Citations among the shared journals are more comprehensively covered in JCR than in S copus, so the network in JCR is denser and more connected than in S copus. The ranking of shared journals in terms of indegree (i.e., numbers of citing journals) or total citations is similar in both databases overall (S pearman rank correlation ρ > 0.97), but some individual journals rank very differently. Journals that are unique to S copus seem to be less important—they are citing shared journals rather than being cited by them—but the humanities are covered better in Scopus than in JCR.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
The shorter time frame of citation coverage in Scopus may be compensated by its wider overall content coverage.
“These findings suggest that a shorter time frame of citation coverage in Scopus might be very well compensated by the wider overall coverage of content.”

While generally high correlation between journal ranks between WoS and Scopus were observed, considerable variations in rank for individual journals were also noticed.

- The procedure for generating overlay maps on the basis of journals in 2012 can be considered as an update to the one for 2011 data (Leydesdorff, Rafols, & Chen, 2013). However, clustering is now based on the algorithm provided in VOSviewer as the default. The number of journals included in 2012 is 10,936 (JCR 2012 for the Science Edition and Social Science Edition combined, October 2013). The map is based on the 10,546 journals (96.4%) in the largest component. The map can be compared with a similar map using Scopus data; see at http://www.leydesdorff.net/scopus12 and the instruction in Appendix 2 below.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
