Correlation between universities' Altmetric Attention Scores and their performance scores in Nature Index, Leiden, Times Higher Education and Quacquarelli Symonds ranking systems.

Objective: Altmetrics are claimed to measure the scientific, societal, educational, technological and economic impacts of science. They have some of these dimensions in common with university ranking and evaluating systems. Their results are, therefore, expected to be partially convergent with the systems'. Given the importance of the scientific and non-scientific impacts of science, this study investigated the correlations of universities' altmetrics with their total and dimensional scores in Nature Index, Leiden, Times Higher Education (THE) and Quacquarelli Symonds (QS). Methodology: Following a correlational design, it explored an available sample of the universities commonly ranked in the systems in 2017. The data were collected from online documents using checklists and analysed by the Spearman correlation. As Altmetric Attention Score (ASS) is efficient in that it integrates several indicators into a single one, it was used as the proxy of the universities' social performance. Findings: The universities showed significant positive correlations between their ASSs and their performance scores on the total and dimensional levels, except for industry income in THE, with an insignificant correlation, and proportion of collaborative publication less than 100 km. in Leiden, with an inverse correlation. The correlations ranged from weak to marginally strong. Conclusion: The positive relationships between the universities' performance and ASSs signified that there existed some similarities in what they measured. However, they were of weak-to-marginally strong powers, implying that the metrics differed in what they measured. The findings contribute to the existing knowledge by providing some evidence of convergence between university-level altmetrics and university performances in various dimensions.
