More rigorous checking targets hyper-authorship, excessive self-citation and unusual patterns of group citation activity
(18 Nov 2023) The Highly Cited Researchers list for 2023 recognizes 6,849 influential researchers at universities, research institutes and commercial organizations around the world who have demonstrated significant and broad influence in their research.
However, Clarivate’s Institute for Scientific Information (ISI) warned of a concentration of talent, with 84 percent based in just 10 countries.
The evaluation and selection process – which draws on data from the Web of Science citation index – was expanded this year to respond to a rise in threats to research integrity.
Enhanced qualitative filters were used to identify publication anomalies including extreme levels of hyper-authorship, excessive self-citation or unusual patterns of group citation activity, which warrant exclusion from the list.
As a result, more than 1,000 researchers were excluded from the final list this year – up from 550 in 2022, which was also nearly double the number seen the year before.
