摘要
【目的】将动态权重百分位数(Dynamic Weight Percentile Rank Score,DPRS)指标应用于跨学科期刊的评价,并与现有的文献计量指标进行对比。【方法】以《期刊引证报告》数据库中5个学科的期刊作为评价对象,对期刊的DPRS、百分位数(Percentiles Rank Scores,PRS)、5年影响因子、篇均被引频次、平均百分位、来源标准化篇均影响力(Source Normalized Impact per Paper,SNIP)等指标进行相关性分析,在此基础上针对DPRS和PRS 2个指标在期刊评价中的效果与区别进行了实证研究。【结果】DPRS与篇均被引频次、5年影响因子、平均百分位、SNIP指标均高度相关,可以消除学科不同带来的引文差异性,并且能够充分综合期刊在各百分位区间"相对数量"和"相对质量"2个方面的信息,且具有比其他类似指标更高的区分度和精准度。【结论】DPRS指标能合理综合论文数量和被引频次分布2个方面的信息,可以实现跨学科期刊的评价,并且能够揭示期刊学术影响力的更多细节。
[Purposes]The dynamic weight percentile rank score( DPRS) is applied to the interdisciplinary journal evaluation,and it is compared with the existing bibliometric indicators. [Methods]Taking the journals of five subjects in Journal Citation Report database as evaluation objects,DPRS,percentiles rank scores( PRS),5-year impact factor( IF),average citation frequency,average percentile,and source normalized impact per paper( SNIP) were analyzed by correlation analysis. On this basis,we made an empirical study on the effect and difference between the two indicators of DPRS and PRS in journal evaluation. [Findings]The empirical results show that DPRS is significantly correlated with indicators of 5-year IF,average citation frequency,average percentile,SNIP,and the DPRS indicator. The DPRS can eliminate the citation differences in different disciplines,and also can fully integrate the two aspects of " relative quantity" and " relative quality" in the percentile intervals of journal. It has high degree of division and precision compared with other similar indicators. [Conclusions] The DPRS indicator can integrate the two aspects of total number of papers and total citation frequency. It can be used for the interdisciplinary journal evaluation and shows the details of the academic influence of journals preferably.
