“…Based on early citation features (Abrishami and Aliakbary, 2019) and bibliometric features (Hu et al, 2020), scholars have introduced social network features (Colladon et al, 2020), semantic features (Ma et al, 2021) and altmetric indicators (Thelwall and Nevill, 2018) into prediction. In addition, some scholars have analyzed the association between papers' impact and other paper factors, such as keyword popularity (Hu et al, 2020), disciplinary differences (Yang and Qi, 2021), interdisciplinary components' citation intensity (Chen et al, 2021), journal rank (Doulani, 2021), conference paper venue (Bedogni et al, 2022), the number of publications made by the authors (Wijewickrema, 2022) and whether the paper is published according to the author-pays charges model (Amjad et al, 2022). Most existing regression models rely on early citation features.…”
