R指数、AR指数:h指数功能扩展的补充指标

R-index and AR-index:Complementing Indicators to h-index

分析了h指数功能扩展后在科学家个人科研绩效评价中的三个缺陷,即缺乏灵敏度,缺乏区分度,缺乏波动性。针对这些缺陷,提出了R指数和AR指数。R指数用于解决h指数的灵敏度和区分度的问题;AR指数用于解决h指数只升不降的问题。利用17位普赖斯奖得主的论文数量和被引频次数量进行了h指数、R指数和AR指数的测算。针对h指数与R指数或AR指数配伍使用后的双因素问题,设计了标准化(h,R)指数和等效(h,R)指数。实测数据证明R指数和AR指数是h指数功能扩展的补充指标。

Limitations of expanding h-index on the evaluation of individuals＇ performance were analyzed, involving in its less sensitivity, less differentiability and less undulation. Thus, R-index was put forward for compensating for the first two limits and AR-index, derived from R-index, for the last one. Firstly, h-index, R-index and AR-index were calculated on data of 17 Price Prize winners. Then, two indices compounds - normalization （h,R） index and equivalent （h,R） were designed to avoid the effect of two factors involved and each index was measured by coupled with the others. It showed that there were significant correlations of h- index with R-index, h-index with AR-index and R-index with AR-index. Therefore, both R-index and AR- index are good complementary indicators to h-index with function expanded.
