Research Talks (Nanjing University visitors)

Join the Center for Informatics Research in Science and Scholarship (CIRSS) for two short research talks at the intersection of informetrics, scientometrics, and bibliometrics.

Helena H. Zhang, doctoral candidate at the School of Information Management at Nanjing University, will present "Measuring Interdisciplinarity of Nobel Laureates’ Key Publications."
Abstract:  Around the research question whether larger or smaller interdisciplinarity benefit scientific output with high quality, two indicators Brillouin’s index (BI) and Hill-type index (HI) are applied to measure interdisciplinarity. For the key publications of Nobel laureates during 2001 to 2010, both BI and HI indicate that smaller interdiciplinarity benefits creative works of these Nobel laureates. The research findings keep high concordance between BI and CI, with high correlation (>0.8). Although all values, within BI < 1 and HI <12, show that the interdisciplinarity is always small in the sample, it is also shown that the interdisciplinary studies distributes wider in the field of physiology or medicine than that of physics.

Ronda J. Zhang, doctoral candidate at the School of Information Management at Nanjing University, will present "Analyzing the Collaborative Networks and Visualizing Their Cores on Three Research Hot Topics in Biomedicine."

Abstract:  Network analysis and information visualization are applied to study three research hot topics in biomedicine, namely H1-CRISPR, H2-iPS cell and H3-Synthetic biology. The research reveals that there are core countries, core institutions and core authors in the studies on these hot topics. By top 5% collaborative networks, USA is the top 1 in core countries, Harvard, MIT and Berkeley are top 3 in core institutions, and different core authors distribute in different topics. Core authors may affect scientific progress via their highly cited top articles, where biomedical examples provided empirical case studies.
