摘要/Abstract

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_D_Z和绝对性颠覆性指数D_Z；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_D_Z算法解决了D关于N_R非单调的问题，D_Z算法解决了D关于N_F、N_B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_D_Z和D_Z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_D_Z and D_Z as alternatives to solve the inconsistency problem of D. Finally, the factors affecting Rela_D_Z and D_Z were studied from the perspective of citation time window, discipline difference and document types.[Result/conclusion] Rela_D_Z avoids the inconsistency problem by solving the non-monotonic problem of D with respect to N_R. D_Z overcomes the non-strict monotonic problem of D with respect to N_F and N_B. Taking into account the relative and absolute disruption index will result in more reasonable results. In addition, Rela_D_Z and D_Z are influenced by citation time window, disciplines and document types. Necessary processing steps are needed when applying the disruption index.

Key words: disruption index, creativity, inconsistency, scientific evaluation, citation analysis
