Abstract
• The network is highly centralized by Generalist media from English-speaking countries • The blogs network is less centralized, shaped by thematic groups on specialized hubs • The centralized model acts as echo chambers amplifying the attention of publications This study aims to explore the connections between news and blogs based on the co-mention of research papers. This approach attempts to generate several network graphs that show the structural topology of blogs and news media, stressing possible differences between blogs and news when they come to co-mention research publications. 3,810 blogs and 3,387 news outlets that cite 100,529 research articles were displayed in network graphs using citation coupling. Country, language and thematic category were added to each medium. The findings show that the network of blogs and news is characterized by scale-free properties. The news network is highly centralized by general-interest news outlets from English-speaking countries, while the blogs network depicts a less centralized and low-density network, shaped by well-defined thematic clusters that rest on prestigious specialized hubs. The study concludes that these structures have important implications for the media impact of scholarly publications. In the case of news, the highly centralized model on general-interest news outlets acts as echo chambers amplifying the attention of publications. In the case of blog, the impact is less and would be borne by specialized blogs in specific thematic areas.
Highlights
The study of the research impact in bibliometrics has been defined by the exclusive analysis of bibliographic citations
It means that the environment in that a research output impacts is the same than the one that produced it
Since 2017, when Plum Analytics was acquired by Elsevier, it captures the online footprint of any publication indexed in the Scopus database (Elsevier, 2017)
Summary
The study of the research impact in bibliometrics has been defined by the exclusive analysis of bibliographic citations. The times that a publication is mentioned in the subsequent literature has become the main proxy to value the impact of scientific publications, authors and organizations (Garfield, 1970). This approach implies a reflected view in which the object of study (cited publications) is the subject of analysis (citing publications). It means that the environment in that a research output impacts is the same than the one that produced it This closed surrounding causes that the reach of the bibliometrics is only circumscribed to the academic impact, the impact of scholarly publications in their own community (Aguinis et al, 2014). In this form, the research evaluation according to bibliometrics could be considered an internal evaluation of how the science perceives their own results (Ozanne et al, 2017)
