基于代表作制度的z指数学者评价方法改进研究

Research on the Modification to Z Index Researcher Academic Evaluation Method Based on Representative Work System

文章以代表作制度为基础,使用h指数核心法和representative方法选取学者代表作,对Prathap提出的Z指数原理进行改进,探讨不同计算原理的评价效果,并通过图书情报学领域的实证分析,讨论每种指数的特征。研究发现:如果学者少量论文被引量显著高于其他学者,则有可能获得更好的Zr指数排名;如果学者的h指数核心论文的总被引量较高,则有可能获得较好的Zh指数排名;如果学者的全部论文被引量相对来说比较平均,则有可能获得较好的Z指数排名。在实际工作中需要根据评价目的选择合适的方法,以发挥出学术评价本身的意义。

Based on h index and P index,Prathap introduced the citation concentration indexηinto Z index to make the distribution of citations emits its effects in evaluations.However,the calculation principle makes it difficult to find the authors who have a few highly cited papers.To overcome this limitation some modifications are made in this study.Based on the representative work system,the paper uses h index core method and representative method to select representative works of researchers and improve the principle of Z index.The evaluation result of different calculation principles is discussed,the characters of each index are analyzed by empirical research of library and information science.The result shows that Zr index maybe favors the authors who have a few highly cited papers;Zh index favors the authors whose h core papers citations are high;Z index favors those who have a relative average distribution of citations.In order to make the academic evaluation work at full capacity,one needs to select an appropriate method according to the evaluation purpose.
