评价领域作者影响力的新指标——v指数

A New Improved Indicator for the Influence Evaluation of the Field—v-index

基于文献计量新指数x指数,提出了一个新的评价研究人员学术水平改进指标——v指数,其最突出的优势是将作者的署名位次和作者数量纳入讨论范围。为检验v指数的效果,从CNKI网络出版总库中挑选出"图书情报与数字图书馆"学科内发文数量排名前36位作者的文献记录,统计每位作者的论文数量、单篇被引次数、总被引次数、作者署名位次以及作者数量等数据,并以此为对象进行实证分析。结果表明,与传统的评价指数相比,v指数对作者署名位次和作者数量敏感,评价结果更加精细,可以为评估领域内作者影响力提供有效参考。

A new improved index, defined as v-index, is proposed on the basis of the x-index which is a new bibliometric index assess- ing academic level of researchers. The most prominent advantage of v-index is that it is sensitive to the author＇s signature order and the number of authors. To test the effect of the v-index, the paper selects the records of the top 36 authors by descending order of the number of their articles in subjects of ＂Library and Information Science and Digital Library＂ from CNKI and calculates data including each author ＂s number of papers, citation times of a single article, total citation times, author＇s signature order and the number of authors and so on. These data are then used as objects for further empirical analysis. The results show that v-index is sensitive to the author＇s signature order and the number of authors and its evaluation results are more precise compared to some traditional evaluation indexes. So it can provide a very effective reference to assess the influence of authors in the field.
