This article examines the extent to which specific features of interdisciplinary research are accurately reflected in selected bibliometric measures of scholarly publications over time. To test the validity of these measures, we compare knowledge of research processes and impact based on ethnographic studies of a well-established researcher’s laboratory, together with personal interview data, against bibliometric indicators of cognitive integration, diffusion, and impact represented in the entire portfolio of papers produced by this researcher over time.

The U.S. National Science Foundation Research Coordination Network (RCN) program broke new ground in funding the development of new research communities of practice. This assessment of RCN supports the conclusion that networking activity was increased for a sample set of projects compared to a control group. Journal articles resulting from RCN support score as highly interdisciplinary. Moreover, those articles appear as notably influential, being published in high impact journals and being highly cited. The RCN program does indeed seem to be fostering new biological science research networks.

This “country study” analyzes substantial samples of research papers by Brazilian authors drawn from two global databases. The approach and the findings may each be of interest. Our approach is to examine R&D outputs through bibliometrics (to identify key authors, institutions, journals, etc) and text mining with taxonomy generation (to identify pervasive research thrusts). We extend prior country studies by providing for interactive data access and exploring military-relevant R&D information. The resulting publication activity profiles provide insight on Brazilian R&D strengths and investment strategies, and help identify opportunities for collaboration. Brazil, a nation of 190 million, evidences a substantial research …
Is Science Becoming More Interdisciplinary? Measuring And Mapping Six Research Fields Over Time, Alan L. Porter, Ismael Rafols
Is Science Becoming More Interdisciplinary? Measuring And Mapping Six Research Fields Over Time, Alan L. Porter, Ismael Rafols

In the last two decades there have been studies claiming that science is becoming ever more interdisciplinary. However, the evidence has been anecdotal or partial. Here we investigate how the degree of interdisciplinarity has changed between 1975 and 2005 over six research domains. To do so, we compute well-established bibliometric indicators alongside a new index of interdisciplinarity (Integration score, aka Rao-Stirling diversity) and a science mapping visualization method. The results attest to notable changes in research practices over this 30 year period, namely major increases in number of cited disciplines and references per article (both show about 50% growth), and …
