科学家个人学术影响力随时间变化的计算方法研究

A Study on the Computing Method of the Individual's Academic Impact Over Time

[目的 /意义]研究如何动态地评价科学家个人学术影响力的方法和探索研究科学家个人学术影响力时序曲线的意义。[方法 /过程]用基于每n年和基于逐年个人发文和引用的学术影响力计算方式,对76名诺贝尔物理学奖获奖者的学术影响力时间变化趋势进行分析,并比较了基于每n年个人发文和引用的学术影响力计算方式下基于传统文献计量学指标和类h指数的特点。[结果 /结论]得出了恰当的个人学术影响力随时间变化的计算方式和分析指标特点。

[Purpose/significance] Studying how to choose the method of dynamic evaluation of individual academic impact and exploring the significance of individual academic impact curve. [Method/process] Based on the analysis of the academic in- fluence of each n year and the annual individual posting and citation, the time changes trend of the academic influence of 76 Nobel prize winners in physics were analyzed. The characteristics of traditional bibliometric index and h expansion index were compared. [ Resuh/Conclusion] The appropriate calculation model and the characteristics of individual academic impact index were obtained.
