Disruption index depends on length of citation window
In the context of recent developments in scientometrics to measure novelty or creative potential, Wu, Wang, and Evans (2019) propose a new disruption index that measures the extent to which a publication disrupts the field of science. We calculated the disruption index for some example papers. The analyses of the index values (using our Web of Science in-house database) show that they depend on the citation window (the period of time over which citations are collected).
