作者个人影响因子的修正研究

Revision of the Author's Personal Impact Factor

自2014年S.Fortunato根据期刊影响因子的思想提出作者影响因子(AIF)后,AIF指标在国际上引起人们的关注和研究,但国内对该指标研究较少。本文在现有AIF研究的基础上,针对AIF存在的不足对其进行修正得到CPIF(即Corrected Peronal Impact Factor),然后,以图书情报学领域40名同时具有高影响力和高发文量的作者为研究对象,利用CPIF指标评价其学术影响力,并分析其灵敏度、区分度与合理性,提出计算作者学术水平的综合性评价指标。结果表明,CPIF与H指数、AIF具有相关性;与H指数相比,CPIF的灵敏度、区分度更高;与AIF相比,CPIF的波动幅度更小,评价结果更稳定;CPIF能够综合反映5年时间窗口内作者发文和被引论文的数量和质量,评价结果更加全面精细,并在评价青年作者的学术影响力时效果更佳。

Since S.Ortunato proposed author impact Factor(AIF)based on the idea of journal impact factor in 2014,AIF index has attracted people's attention and research internationally,but there are few researches on this index in China.Based on the existing AIF research,correct the shortcomings of AIF and obtain CPIF(Corrected Personal Impact Factor),take 40 authors with high influence and high publication volume in the field of library and information science as the research objects,evaluate its academic influence with CPIF index,and analyze its sensitivity,distinction and rationality,proposes a comprehensive evaluation index to calculate the author's academic level.The experimental results show that CPIF is correlated with H index and AIF.Compared with H index,CPIF has higher sensitivity and discrimination.Compared with AIF,CPIF has smaller fluctuation range and more stable evaluation results.CPIF can comprehensively reflect the quantity and quality of papers published and cited by authors within the five-year window,and the evaluation results are more comprehensive and detailed,and the effect is better when evaluating the academic influence of young authors.
