摘要：

【目的】 针对期刊影响力评价的不足,设计期刊标准化颠覆性指数(JNDI)作为期刊创新性评价指标,对药学领域期刊进行评价,推动科技评价体系的发展,促进科技创新。【方法】选取WoS类别“pharmacology & pharmacy”2016年发表的累计引文时间窗7年的29836篇研究型论文作为研究对象,涵盖218种期刊,从WoS、JCR、OpenCitations获取文献、期刊、引文数据,分析各指标的分布、相关性和排名变化,探究RDI和JNDI分别在文献和期刊层面的评价效果。【结果】RDI在各D指数变体中数学性质和评价效果最优,受参考文献数影响最小,JNDI在分布特征和稳定性上优于JDI,能够区分期刊之间的细微差异,JNDI与影响力指标具有中等偏弱的正相关性,期刊JNDI排名与JIF排名具有较大差异。【结论】JNDI可以作为评价期刊创新性的指标,其可靠性较强,可应用于跨学科评价场景,JNDI结合影响力指标可以识别创新性期刊,避免其因为研究领域冷门、所属国家非英语等原因被低估或埋没,JNDI的准确性会受到数据库覆盖率和期刊归类问题的影响,在应用时应当特别注意。

Abstract:

[Purposes] Facing the shortcomings of journal impact metrics evaluation, the journal normalized disruption index (JNDI) was designed as a journal innovation evaluation index, which evaluated journals in the field of pharmacy, to develop the scientific evaluation system and promote scientific innovation. [Methods] We selected 29836 articles classified into the WoS category “pharmacology & pharmacy” published in 2016 with a cumulative citation time window of 7 years as the research objects, covering 218 journals. We extracted papers, journals, and citation data from WoS, JCR, and OpenCitations. We analyzed the distribution, correlation, and ranking changes of each index and explored the evaluation effect of RDI and JNDI on the paper level and journal level. [Findings] RDI, which is least affected by the number of references, has the best mathematical properties and evaluation effect among all the D variants. JNDI has advantages over JDI in distribution characteristics and stability. JNDI can distinguish subtle differences between journals. JNDI has a moderately weak positive correlation with the impact metrics. The journals’ JNDI rankings are quite different from the JIF rankings. [Conclusions] JNDI can be used as an index to evaluate the innovation of journals. It is robust and can be applied to interdisciplinary evaluation scenarios. JNDI combined with the impact metrics can identify innovative journals and avoid them being underestimated due to unpopular research fields, non-English-speaking countries, etc. The accuracy of JNDI will be affected by database coverage and journal classification issues, so special attention should be paid when applying JNDI.
