分位数指标对于期刊评价的应用实证研究

An Empirical Study of Quantile Indicators in Journal Evaluation Field

基于影响因子的设计缺陷,近年来描述引文分布规律的分位数指标受到文献计量学的广泛关注。本研究旨在比较和探讨各类分位数指标在期刊评价中的实际效果,确定应用于期刊评价的最优指标,以期增进学界对于分位数指标的研究和探讨。选择2015年版JCR生物学期刊为研究对象,以In Cites数据库为基础,计算并分析不同分位数指标的期刊评价结果及排名,利用SPSS统计软件比较分位数指标与传统评价指标的相关度,确定应用于期刊评价的最佳指标。实证研究结果表明,复合百分位指标能够矫正5年影响因子的设计缺陷,其中PR6的评价效果最为理想,与同行评议相关度最高,是可用于期刊评价的最优分位数指标。

Due to the defects of influence factor, the quantile indicators have drawn wide attention in bibliometrics in recent years. The aim of this study is to compare and discuss the actual effect of quantile indicators in journal evaluation, and define the best quantile indicator for journal evaluation. 80 kinds of biology journals in JCR 2015 were selected as sample. Based on In Cites database, different quantile indicators were calculated for each journal. The results were compared with the IF5 and peer review results, in order to identify the best quantile indicator. Results showed that the comprehensive quantile indicator can overcome the design defects of IF5. PR6 was the best quantile indicator in journal evaluation with the best evaluation effect and the highest correlation with peer review.
