A new method of calculating the disruption index based on open citation data

This article discusses the method of calculating the disruption index (D index) based on COCI (the OpenCitations Index of Crossref open DOI-to-DOI citations), breaks through the difficulties brought by the acquisition of massive citation data and verifies the reliability of the method of calculating the disruption index based on open citation data based on empirical research. Through empirical research, we found that (1) there is little difference in the number of citation data of focus papers in Web of Science (WoS) and COCI; (2) the levels of disruptive innovation of the papers calculated based on the WoS and COCI are significantly strongly correlated; (3) among the D index and related extended indicators calculated based on COCI, Formula: see text has the strongest correlation with peer-review indicators, which is consistent with the calculation results based on WoS. Given the broad disciplinary coverage of COCI, although it has not yet been able to fully replace the function of commercial citation databases in research assessment, it can undoubtedly serve as an important source of citation data for further the disruption index and other scientometrics research thereafter.
