Top corporate institutions by normalized WFC

The tables show Japan’s leading institutions ranked by normalized weighted fractional count (WFC), an indicator of an institution’s high-quality research output as a proportion of total output in the natural sciences (NS) from 2012 to 2017. This is derived by dividing an institution’s WFC in the Nature Index (WFC 2012–2017) by its total number of natural sciences articles in Scopus (Scopus NS articles 2012–2017). Also listed are an institution’s total number of articles in the Nature Index (AC 2012–2017) and the percentage of its total articles in Scopus that are in the natural sciences (NS articles (%) 2012–2017).
