Citation Counting, Citation Ranking, and h-Index of Human-Computer Interaction Researchers: A Comparison between Scopus and Web of Science

This study examines the differences between Scopus and Web of Science in the
citation counting, citation ranking, and h-index of 22 top human-computer
interaction (HCI) researchers from EQUATOR--a large British Interdisciplinary
Research Collaboration project. Results indicate that Scopus provides
significantly more coverage of HCI literature than Web of Science, primarily
due to coverage of relevant ACM and IEEE peer-reviewed conference proceedings.
No significant differences exist between the two databases if citations in
journals only are compared. Although broader coverage of the literature does
not significantly alter the relative citation ranking of individual
researchers, Scopus helps distinguish between the researchers in a more nuanced
fashion than Web of Science in both citation counting and h-index. Scopus also
generates significantly different maps of citation networks of individual
scholars than those generated by Web of Science. The study also presents a
comparison of h-index scores based on Google Scholar with those based on the
union of Scopus and Web of Science. The study concludes that Scopus can be used
as a sole data source for citation-based research and evaluation in HCI,
especially if citations in conference proceedings are sought and that h scores
should be manually calculated instead of relying on system calculations.
