基于评价时效性的总被引频次评价改进研究

Research on Improvement of Total Citation Frequency Evaluation Based on Evaluation Timeliness

总被引频次作为常用的期刊评价指标,由于涉及到期刊自创办以来所有论文的被引次数,因此其评价时效性不高。为了解决此问题,本文提出采用5年被引频次代替总被引频次来进行评价,并以南京大学CSSCI评价与中国知网CI指数评价为例,基于图书馆情报与文献学CSSCI期刊(2017—2018版)进行了实证研究。结果表明:5年被引频次与总被引频次高度相关,但对排序影响较大;采用5年被引频次会改变CI指数评价的指标相对权重;CSSCI评价的时效性要优于CI指数评价;采用5年被引频次对CSSCI评价的影响小于对CI指数的影响,同时对CSSCI评价与CI指数的统计特征影响不大。建议从提高评价时效性出发,采用5年被引频次代替总被引频次进行评价。图1。表3。参考文献14。

Total citation frequency is a common evaluation indicator to evaluate journals.Because it’s related to the number of citations of all papers since the journal was created,so its evaluation timeliness is not so high.In order to solve this problem,this paper proposes to use the 5-year citation frequency instead of the total citation frequency for evaluation,and takes the CSSCI evaluation of Nanjing University and the CI index evaluation of CNKI as an example,then conducts an empirical study based on library information and documentation journals.The results show that the frequency of citations in 5 years is highly correlated with the total citation frequency,but has a greater impact on the ranking;using 5-year citation frequency will change the relative weight of the index of the CI index evaluation;the timeliness of CSSCI evaluation is better than CI index evaluation;the effect of using 5-year citation frequency on CSSCI evaluation is less than that on CI index;using 5-year citation frequency has little effect on the statistical characteristics of the CSSCI evaluation and the CI index.It is suggested that starting from improving the timeliness of evaluation,evaluation shall be conducted using 5-year citation frequency instead of total citation frequency.1 fig.3 tabs.14 refs.
