Evaluating the state-of-the-art in mapping research spaces: A Brazilian case study
Fig 2
Top left: yearly number of new publication entries (a publication is counted multiple times if it is listed under more than one profile). This metric has been increasing since the mid-90s; decrease in last couple of years may be due to right-censoring. Top right: yearly number of publications entries normalized by number of authors. Between 1990 and 2016, this number has increased nearly 50%. Bottom: Complementary Cumulative Distribution Function (CCDF) of the number of publications per scientist and institution. Both distribution are heavy tailed, but the distribution for institutions seems to follow a power law with cutoff at x = 105.
