This web application visualizes how successful universities or research-focused institutions collaborate. The application is based on papers (articles, reviews and conference papers) published between 2012 and 2016 in several subject areas and in “All areas”. For each subject area (and for “All areas”), those institutions (universities and research-focused institutions worldwide) were selected in the SCImago Institutions Ranking which published at least 500 papers in the publication period. We refer to these institutions as "reference institutions". For every reference institution, the collaborating institutions were identified. Collaborating institutions are those which have co-authored at least ten publications with the respective reference institution. We refer to the collaborating institutions as “network institutions”. We estimated statistical models (Bayesian multilevel logistic regressions). The statistically estimated best paper rates (from the models) which the reference institutions have achieved with its network institutions are visualized. The best paper rate gives the proportion of highly cited papers from an institution and is considered generally as a robust indicator for measuring citation impact. Co-authorship networks (based on institutional affiliations) show how successfully overall an institution (reference institution) has collaborated compared to all the other institutions, and with which other institutions (network institutions) an institution has collaborated best.
