YC-EM'_C指数:时间与合作视角下的作者影响力评价研究

YC-EM'_C Index: A New Approach to Evaluate the Scientific Impact from the Perspective of Time and Co-authorship

[目的/意义]从H指数的提出开始,对科研人员的评估指标研究一直是热点话题。介绍由Bihari学者基于EM指数、YC-H指数提出的YC-EM'指数。[方法/过程]从合作维度改进YC-EM'指数并命名为YC-EM'_C指数。以国外计量学领域54位科学家10年文献数据为实验对象,从作者区分度、作者排名情况,以及与各参数的相关性角度验证YC-EM'_C指数有效性。[结果/结论]YC-EM'_C指数区分性高;作者名次变化明显;与论文数量、署名顺序等具有不同相关性,YC-EM'_C指数的评价结果更符合实际。

[Purpose/Significance]This article introduces a new index,YC-EM'index,for more exact evaluating of authors influence.[Method/Process]This paper takes cooperation into consideration and names YC-EM'C index based on EM index and Year-Based H-indices.An empirical study has been made on 54 scientists'publication data,who are working in scientometrics and bibliometrics fields.The author discriminations,rankings,and correlations of YC-EM'C index with other parameters are discussed in detailed.[Result/Conclusion]The research shows that YC-EM'C index can make more exact evaluating,and has different correlations with number of papers,author's order et al.Co-authorship plays an important role in researcher's scientific assessment.
