“…Some studies have focused on its features, such as author metadata (Ortega, 2015a;Orduña-Malea et al, 2017), bibliometric indicators (Teixeira da Silva, 20182021), citation data accuracy (Doğan, Şencan & Tonta, 2016) or even citation manipulation effects (Delgado López-Cózar, Robinson-García & Torres-Salinas, 2014). Other studies have analyzed the coverage of GSP, either global (Ortega & Aguillo, 2014;Ortega, 2015b) or centered on the presence of specific disciplines (Kim & Grofman, 2020), institutions (Mikki et al, 2015;Ortega, 2015c) or research groups (Thoma & Chan, 2019). Finally, other studies have directly used GSP as a source for bibliometric analyses to carry out co-keyword (Ortega & Aguillo, 2012), institutional collaboration and disciplinary (Martín-Martín, Orduna-Malea & Delgado López-Cózar, 2018) analyses.…”
