Top 100 overall collaborators

Tables are calculated based on average collaboration score or bilateral collaboration score in 2015. The first measure is the average of the share for collaborative papers of the named institution and all its partners. The bilateral collaboration score sums the shares derived from collaborative papers of the two collaborating institutions*.

Footnote

Weighted fractional count (WFC) for each institution is shown to two decimal places only. When two or more institutions have the same WFC, their positions are determined by the thousandth place (or beyond).

These results are based on the most recent data available. Owing to continual refinements of the data, the figures in the database are liable to change and might differ to those printed in the supplements.
