About the Ranking In all, “Highly Cited Researchers 2019” lists the names of some 6000 investigators. The annual ranking is compiled by Clarivate Analytics, whose headquarters are located in Philadelphia. The data used in the analysis are derived from the Web of Science, which contains comprehensive citation records of all research publications. Citation frequency serves as an indicator of the quality of a researcher’s publications and their impact on the work of others in the corresponding field. The analysis takes into account the citation records of research papers published over the course of 11 years. The publications examined for the 2018 list appeared in the period from 2008 to 2018. Importantly, in this ranking exercise, only the top 1% of publications (as gauged by citation frequency) in each subject area are taken into consideration.
