Analyzing, measuringand visualizing the successof interdisciplinarity
Interdisciplinarity• Integration of data, methods and theories of disciplines• Expected to derive results greater than the sum of its
disciplinary parts• Central in science policy and research evaluation
Operationalization in bibliometrics• Measured by co-citations• Conflicting evidence regarding citation impact:
• lower citation impact
• higher citation impact
• no significant difference
Introduction
(e.g., Rinia, van Leeuwen & van Raan, 2002; Levitt & Thelwall, 2008; Larivière & Gingras, 2010)
(e.g., Adams, Jackson & Marshall, 2007)
(e.g., Larivière & Gingras, 2010; Uzzi et al., 2013; Yegros-Yegros, Rafols, & D’Este, 2015)
Are interdisciplinary long-distance relationships worth the effort?
• Does an interdisciplinary knowledge base increase the citation impact of an article?
• Which combinations of subdisciplines lead to the highest citation impact?
• How does the distance between co-cited subdisciplines influence citation impact?

Results
2,940 (5.19%) of 56,614 win-win edgesnode color: discipline │ edge color: mix of adjacent nodes │ labels: subdiscipline with highest number of win-win relationships per discipline (number and percentage of win-win relationships)
Number of papers citing win-win relationships (≥10,000 citing articles)
Results
943 (0.8%) of 113,228 win-win arcsnode color: discipline │ arc color: outgoing node (clock-wise) │ labels: strongest win-win relationships per discipline(mean relative citation rate)
Relative citation rate of win-win relationships (≥5.0 mean citations)
• Co-citing articles from different subdisciplines leads to above average citation impact.
• The more diverse the knowledge base, the higher the citation impact.
Findings support assumption that interdisciplinary research leads to results greater than the sum of its disciplinary parts.
