@article{Leydesdorff_Tekles_Bornmann_2021, title={A proposal to revise the disruption indicator}, volume={30}, url={https://revista.profesionaldelainformacion.com/index.php/EPI/article/view/86387}, DOI={10.3145/epi.2021.ene.21}, abstractNote={<p class="p1">The disruption index (<em>DI</em>) based on bibliographic coupling and uncoupling between a document and its references was first proposed by Funk & Owen-Smith (2017) for citation relations among patents and then adapted for scholarly papers by Wu <em>et al</em>. (2019). However, Wu & Wu (2019) argued that this indicator would be inconsistent. We propose revised disruption indices (<em>DI</em>* and <em>DI<sup>#</sup></em>) which make the indicator theoretically more robust and consistent. Along similar lines, Chen <em>et al.</em> (2020) developed the indicator into two dimensions: disruption and consolidation. We elaborate the improvements in simulations and empirically. The relations between disruption, consolidation, and bibliographic coupling are further specified. Bibliographic coupling of a focal paper with its cited references generates historical continuity. A two-dimensional framework is used to conceptualize dis-continuity not as a residual, but a dimension which can further be specified.</p>}, number={1}, journal={Profesional de la informaciĆ³n / Information Professional}, author={Leydesdorff, Loet and Tekles, Alexander and Bornmann, Lutz}, year={2021}, month={feb.} }
