Exploring the relation between press releases and media coverage of Japanese university research outputs

In recent years, the number of press releases from universities has generally increased over time. How academic research is reported in the media is a big concern for management at universities and for research on the diffusion of scientific knowledge. In this study, we investigate the current situation and analyze the relation between press releases and their coverage in two major national newspapers in terms of the source article’s altmetric attention score, citation, subject field, and collaboration network from 2011 to 2014.
