| 摘 要： | 目的/意义] 解决颠覆性指数在数学性质上存在的不一致性问题,并探讨颠覆性指数在应用中的影响因素。方法/过程] 首先指出颠覆性指数D的不一致性表现,然后对其改进得到相对性颠覆性指数Rela_DZ和绝对性颠覆性指数DZ;最后从引文时间窗、学科差异和文献类型3个角度,分析影响颠覆性指数差异的因素。结果/结论] Rela_DZ算法解决了D关于NR非单调的问题,DZ算法解决了D关于NF、NB不严格单调的问题,从而避免了不一致性;将颠覆性指数的相对性与绝对性两个算法结合,在应用中将更加合理。此外,颠覆性指数Rela_DZ和DZ受引文时间窗、学科和文献类型的影响,因此,在应用时应进行必要的处理。

| Abstract: | Purpose/significance] To solve the inconsistency of disruption index D, and investigate the affecting factors of disruption index in specific applications.Method/process] This paper pointed out the inconsistency problem of disruption index D, and then proposed Rela_DZ and DZ as alternatives to solve the inconsistency problem of D. Finally, the factors affecting Rela_DZ and DZ were studied from the perspective of citation time window, discipline difference and document types.Result/conclusion] Rela_DZ avoids the inconsistency problem by solving the non-monotonic problem of D with respect to NR. DZ overcomes the non-strict monotonic problem of D with respect to NF and NB. Taking into account the relative and absolute disruption index will result in more reasonable results. In addition, Rela_DZ and DZ are influenced by citation time window, disciplines and document types. Necessary processing steps are needed when applying the disruption index. |
