Interdisciplinarity,Temporal Diversity,and Scientific Impact:Perspective on References
Building on the concept of interdisciplinarity,this study proposes a measurement framework for temporal diver-sity,quantifying it into four dimensions:temporal richness,temporal imbalance,temporal disparity,and temporal depth.The study meticulously analyzes the temporal trends and distribution characteristics of interdisciplinarity and temporal di-versity,as well as the career evolution patterns of high-level scientists,using 38,879,575 scientific papers from the Micro-soft Academic Graph database spanning from 1950 to 2020.The relationship between interdisciplinarity,temporal diversi-ty,and scientific impact is further explored.The findings reveal that:(1)The interdisciplinary and temporal diversity of pa-pers exhibits a consistent growth trend that differs depending on the field.(2)Both interdisciplinarity and temporal diversi-ty indicators show heterogeneous distribution characteristics,such as scale-free distribution,and a weak correlation exists between them.(3)In the careers of high-level scientists,both interdisciplinarity and temporal diversity show significant growth trends,largely attributable to an increase in the number of their referenced papers.(4)Interdisciplinarity and tempo-ral diversity have opposite effects on scientific impact with interdisciplinarity significantly promoting scientific impact and temporal diversity significantly inhibiting it,suggesting that a combination of strong interdisciplinarity and weak temporal diversity has the highest probability of becoming a disruptive hotspot paper.The temporal diversity measurement frame-work proposed in this study enriches the theories of knowledge integration and interdisciplinarity,providing insights into science and technology policy and academic evaluation.
