2010 arXiv   pre-print
A citation-based indicator for interdisciplinarity has been missing hitherto among the set of available journal indicators.  ...  In this study, we investigate network indicators (betweenness centrality), journal indicators (Shannon entropy, the Gini coefficient), and more recently proposed Rao-Stirling measures for "interdisciplinarity  ...  Acknowledgement We are grateful to Ulrik Brandes, Wouter de Nooy, and Andrew Stirling for suggestions and comments.  ...

Diversity of references as an indicator of the interdisciplinarity of journals: Taking similarity between subject fields into account

Lin Zhang, Ronald Rousseau, Wolfgang Glänzel
2015 Journal of the Association for Information Science and Technology  
In the first part, the properties of this measure are discussed, and, on the basis of these properties it is shown that the measure has the potential to serve as an indicator of interdisciplinarity.  ...  The objective of this article is to further the study of journal interdisciplinarity, or, more generally, knowledge integration at the level of individual articles.  ...  Acknowledgment The first author acknowledges the National Natural Science Foundation of China Grant (71103064), Universities innovation team of philosophy and social sciences support plan in Henan province  ...

Interactive Overlays of Journals and the Measurement of Interdisciplinarity on the basis of Aggregated Journal-Journal Citations [article]

Loet Leydesdorff, Ismael Rafols, Chaomei Chen
2013 arXiv   pre-print
The maps are based on the 10,000+ journals contained in the Journal Citation Reports (JCR) of the Science and Social Science Citation Indices (2011).  ...  Since this indicator of interdisciplinarity is normalized between zero and one, the interdisciplinarity can be compared among document sets and across years, cited or citing.  ...  We acknowledge support by the ESRC project 'Mapping the Dynamics of Emergent Technologies' (RES-360-25-0076).  ...

Quantifying the interdisciplinarity of scientific journals and fields

F.N. Silva, F.A. Rodrigues, O.N. Oliveira, L. da F. Costa
2013 Journal of Informetrics  
In this paper we quantified the interdisciplinarity of scientific journals and science fields by using an entropy measurement based on the diversity of the subject categories of journals citing a specific  ...  The methodology consisted in building citation networks using the Journal Citation Reports database, in which the nodes were journals and edges were established based on citations among journals.  ...  Acknowledgements This work was supported by FAPESP, CAPES, and CNPq (Brazil).  ...

Betweenness and Diversity in Journal Citation Networks as Measures of Interdisciplinarity -- A Tribute to Eugene Garfield -- [article]

Loet Leydesdorff, Caroline S. Wagner, Lutz Bornmann
2017 arXiv   pre-print
Using betweenness centrality (BC) and diversity, we elaborate on the question of how to distinguish and rank journals in terms of interdisciplinarity.  ...  Because the citation networks in the cited direction reflect both structure and variation, diversity in this direction is perhaps the best available measure of interdisciplinarity at the journal level.  ...  Acknowledgement We thank Wouter de Nooy for advice and are grateful to Thomson Reuters for JCR data.  ...

Interdisciplinarity at the Journal and Specialty Level: The changing knowledge bases of the journal Cognitive Science [article]

Loet Leydesdorff, Robert L. Goldstone
2013 arXiv   pre-print
"Interdisciplinarity" should be defined differently at the level of journals and of specialties.  ...  The fluidity and fuzziness of the interdisciplinary delineations in the different visualizations can be reduced and clarified using factor analysis.  ...  Acknowledgement We are grateful to Andrei Mogoutov and Peter van den Besselaar for comments and suggestions, and to Thomson-Reuters for allowing to use their data.  ...

Characteristics of interdisciplinary research in author keywords appearing in Korean journals

Sunyoung Kwon
2018 Malaysian Journal of Library & Information Science  
In addition, the interdisciplinarity degree of 80 percent of the keywords were low, between 0 and 0.499.  ...  This indicates that the majority of author keywords for academic papers do not show interdisciplinarity. Meanwhile, certain author keywords had a fairly high interdisciplinarity degree.  ...  (Leydesdorff 2007) used Betweeness centrality in addition to the Brillouin index in order to measure the interdisciplinarity of academic journals.  ...
