Comparison of Bibliographic Data Sources: Implications for the Robustness of University Rankings
Universities are increasingly evaluated, both internally and externally on the basis of their outputs. Often these are converted to simple, and frequently contested, rankings based on quantitative analysis of those outputs. These rankings can have substantial implications for student and staff recruitment, research income and perceived prestige of a university. Both internal and external analyses usually rely on a single data source to define the set of outputs assigned to a specific university.
This paper presents a first attempt to analyse Open Access integration at the institutional level. For this, we combine information from Unpaywall and the Leiden Ranking to offer basic OA indicators for universities. OA indicators are also disaggregated by green, gold and hybrid Open Access. We then explore differences between and within countries and offer a general ranking of universities based on the proportion of their output which is openly accessible.
The Times Higher Education University Impact Rankings assess universities against the United Nations' Sustainable Development Goals. Calibrated indicators are used to provide comprehensive and balanced comparisons across three broad areas: research, outreach, and stewardship. This first edition includes more than 450 universities from 76 countries.
Overall, the most elite ranks of Europe’s Most Innovative Universities have held steady from last year. The list was compiled in partnership with Clarivate Analytics, and is based on proprietary data and analysis of patent filings and research paper citations.
