“…The proper assessment of uncitedness is important for research policies (Garfield, 1991;Seglen, 1992;van Noorden, 2017). Information scientists made a large contribution to the empirical characterization of the number and composition of uncited papers, they studied how uncitedness depends on the discipline, document kind, country, and year (Dorta-Gonzalez, Suarez-Vega, & Dorta-Gonzalez, 2020;Hou & Ye, 2020;Thelwall, 2016a;van Leeuwen & Moed, 2005;Wallace, Lariviere, & Gingras, 2009). The measurements of uncitedness have been recently reviewed by Nicolaisen and Frandsen (2019) and a summary of the subject has been presented by van Noorden (2017) and Sugimoto and Lariviere (2018).…”
