What does collaboration and innovation look like?
I referenced Annabelle McGilvray’s article in Nature in 2016 and now, thanks to Niall Byrne @scienceinpublic for the link to the new Nature Index for Melbourne.
The Nature Index tracks high-quality research and collaborations by measuring the contribution of institutions and, by extension, cities and countries, to a set of high-quality journals in the natural sciences.

An institution’s contribution to these journals is its fractional count (FC), while article count (AC) is the number of an institution’s journal articles that appear in the Nature Index.
When evaluating the collaborative effort between two institutions, a bilateral collaboration score (CS) is derived. This is sum of the FCs from articles with authors from both institutions. Local bilateral collaborations between institutions within the greater city area are represented by the lines on the map, while the top international bilateral collaborations are listed in a popup box of each institution.
