2021 Virtual Forums
To continue the good work of “TechMining” outside of the annual conference, the GTM program committee is sponsoring a series of virtual forums. The objective of these bi-monthly forums is to share current research in progress, obtain in-depth peer feedback on methods, match approach to research type, data issues, etc., and build relationships for future collaborations. The hour-plus format will consist of three short presentations followed by extended open discussion and Q&A. To allow for rich interchange, registration is free but limited. Zoom will be the participation platform.
September 16, 2021 – 8:00 am – 9:00 am EDT (GMT -4) IDR Measurement and Impact REGISTER
Interdisciplinary scientific research (IDR) extends and challenges the study of science on a number of fronts. Moderator Ying HUANG (KU Leuven, Wuhan University) will engage panelists – Loet LEYDESDORFF (University of Amsterdam) and Lin ZHANG (Wuhan University) for detailed comments on two presentations:

“Interdisciplinarity vs Unidisciplinarity: A Structural Comparison of Multi-generation Citations and References“
This presentation compares the structural characteristics between the citation/reference cascades (networks containing multi-generation citations and references) of interdisciplinary and unidisciplinary papers. By constructing multiple citation/reference cascades for each publication in the American Physical Society (APS) dataset, we found that: (1) for papers having a similar number of references, interdisciplinary papers tend to have a smaller and less ‘radioactive’ knowledge foundation than unidisciplinary papers, though the knowledge foundation of interdisciplinary papers is more heterogeneous; (2) for papers having a similar ‘direct’ scientific impact, unidisciplinary papers have a relatively greater ‘indirect’ impact, which indicates that the scientific impact of unidisciplinary papers is ‘deeper’ and more persistent; and, (3) compared to unidisciplinary papers, there exists at least a short time in which interdisciplinary papers trigger more follow-up discussions.

“A multidimensional framework to quantify interdisciplinary knowledge flow“
A multidimensional framework to quantify interdisciplinary knowledge flow
Abstract: Many indicators on interdisciplinarity have been proposed, using the diversity of knowledge or expertise as a proxy. However, some researchers, for instance, Wang and Schneider (2020), recently voiced their concerns on the current measurement of interdisciplinarity and claimed that they are “confusing and satisfactory”. In this talk, we will review the trajectory of interdisciplinarity measurement and briefly summarize the rationale behind recent criticisms. To offer a different perspective, we propose a multidimensional framework to quantify interdisciplinary knowledge flow to contribute to the task of indicating interdisciplinarity. We demonstrate the capability of this framework by examining the knowledge flow among disciplines regarding their citations patterns, asymmetry, and temporal evolution.
