“Highly Cited Researchers” from Clarivate Analytics is an annual list recognizing influential researchers in the sciences and social sciences from around the world. In 2019, fewer than 6,300, or 0.1%, of the world’s researchers, across 21 research fields, have earned this exclusive distinction. The list of Highly Cited Researchers 2019 identifies researchers at over 1,200 institutions across more than 60 countries.
The list focuses on contemporary research achievement: only highly cited papers in science and social sciences journals indexed in the Web of Science* Core Collection during the 11-year period 2006-2016 were surveyed. Highly cited papers are defined as those that rank in the top 1% by citations for field and publication year. This percentile-based selection method removes the citation advantage of older papers relative to recently published ones, since papers are weighed against others in the same annual cohort. The data derive from Essential Science Indicators (ESI), a component of InCites. The fields are also those employed in ESI — 21 broad fields defined by sets of journals and exceptionally, in the case of multidisciplinary journals such as Nature and Science, by a paper-by-paper assignment to a field based on an analysis of the cited references in the papers.
Recently, Highly Cited Researchers introduced a new Cross-Field category to identify researchers with substantial influence across several fields during 2006-2016. 2,020 researchers with Cross-Field impact now join 4,058 who have been selected in one or more of 21 broad ESI fields. An increase of 50% is substantial, but 6,078 researchers still represents a very small fraction of all scientists and social scientists actively publishing today. Gökhan S. Hotamışlıgil was selected to be on that list.
* Web of Science is the largest publisher-neutral citation index, powering global discovery and citation analytics across the sciences, social sciences and art & humanities. With over 1.4 billion cited references going back to 1900 and millions of users per day – from leading government and academic institutions and research-intensive corporations – Web of Science citation network serves as the foundation for the Journal Impact Factor, InCites and other powerful and trusted citation-impact measures. The Web of Science helps researchers, research institutions, publishers and funders discover and assess the citation impact of over a century of research publications found in the most prestigious journals, books, and conference proceedings.
