h-bar指数述评与案例研究

Research on H-bar-index and Case Study

【目的/意义】由于h指数没有考虑论文合作者的数量,为了提升h指数,会导致名义署名和团队合作规模越来越大的可能。【方法/过程】Hirsch提出:h-bar指数旨在鼓励给独立创作的研究人员加分,同时支持一定的团队合作。该指数与以往根据作者署名区分贡献的h指数改进研究视角不同,h-bar重点考虑以下三种情况的论文纳入h-bar核:(1)独立署名成果;(2)论文被引次数大于h-bar但对其他合著者的h核没有贡献的论文;(3)与其合作论文的其他作者h指数小于其h指数。【结果/结论】本文通过对物理学领域具有合作关系的8位研究人员的h指数和h-bar指数的计算和比较,h-bar虽然能提升h指数的公正性和客观性,但是在推广和计算难易度方面仍存在障碍。

【Purpose/significance】The number of the authors in a paper is not considered by h-index, which may lead to the nominal authorship and more massive scientific collaboration.【Method/process】The h-bar index advanced by Hirsch aims to advocate single authorship and also appropriate cooperation.Eight researchers in physics field with cooperation are computed in terms of h and h-bar.【Result/conclusion】H-bar is more objective and justice than h index, but is harder to promote and compute.
