A 2021. évi sanghaji egyetemi rangsor statisztikai vizsgálata a Scopus/SciVal adatbázisok segítségével.

ARWU (Academic Ranking of World Universities) is one of the three major university rating organisations, along with QS and THE. The latter two organisations compile their publication and citation data using the Scopus database, while the ARWU ranking is based on the Web of Science (WoS) database. The aim of this paper is to study whether the data from the Scopus and SciVal databases allow the estimation of rankings based on WoS. The paper also analyses, based on the selected variables, the country affiliation of the universities included in the ARWU ranking. Next, the authors analyse whether the variables selected from the Scopus/SciVal datasets may be used to definethe next year's ranking. In order to completethis task, the authors estimate the ranking of 2021 using 2020 data. Finally, the group of 1,000 universities according to statistical variables are presented. The study is seeking to answer the question of how each cluster's composition depends on the country where the universities belong. [ABSTRACT FROM AUTHOR]
