Nature Index
The Nature Index is a database that tracks institutions and countries/territories and their scientific output since its introduction in November, 2014.
Methodology
The Nature Index attempts to objectively measure the scientific output of institutions and countries, taking into account differences in quality. Therefore, only articles published in 145 selected high-quality journals are counted. These journals were selected by independent committees. If authors from several institutions and/or countries are involved in a scientific article, it is divided accordingly, assuming that all researchers were equally involved in the article. For example, this "fractional count" (Share) received by each author would be 0.1 for an article with 10 authors. If an author is affiliated with more than one institution, that author's Share is then subdivided equally across their affiliated institutions. The process is similar for countries/territories and regions, though the fact that some institutions have overseas labs makes the process more complicated, with such labs being counted towards their appropriate host countries.[2][3]
