Highly Cited Researchers (HCR) from Clarivate Analytics (formerly known as the Intellectual Property & Science Business of Thomson Reuters) is an annual list recognizing influential researchers in the sciences and social sciences from around the world. 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 past 10-year period were surveyed. Highly cited papers are defined as those that rank in the top 1% by citations for field and publication year.
