网上发表日期对科技论文文献计量指标的影响

The influence of online posting dates on the bibliometric indicators of scientific articles

Mercedes Echeverria, David Stuart, Jose-Antonio Cordon-Garcia

摘要:

本文分析了在线文章和相应的印刷出版物之间的时间差异,以及它如何影响两个文献计量学指标:期刊影响因子(JIF)和即时性指数。这项研究检查了18,526篇文章,完整收集了2013年和2014年61种泌尿学和肾脏学期刊发表的文章和评论。研究结果表明,先进的在线出版(AOP)加速引用的文章,并影响JIF和即时性指数值。关于JIF值,有或没有AOP的期刊之间的比较显示出统计学显著差异(P=0.001,Mann-Whitney U检验)。JIF和在线印刷出版延迟中位数之间的Spearman相关性在统计学上并不显著。至于即时性指数,发现2014年出版的期刊的在线到印刷出版延迟中位数存在显著的Spearman相关性(rs=0.280,P=0.029),尽管2013年出版的期刊没有发现统计学显著的相关性。大多数期刊(n=52的61)发表了他们的文章在AOP。分析还显示了不同的出版商做法:8种期刊没有在全文中包括在线发布日期,9种期刊发表的文章显示了两种不同的在线发布日期-期刊网站上提供的日期和Elsevier的Science Direct提供的日期。这些做法表明,需要透明和标准化的AOP日期的科学文章计算期刊的文献计量指标。

英文摘要:

This article analyses the difference in timing between the online availability of articles and their corresponding print publication and how it affects two bibliometric indicators: Journal Impact Factor (JIF) and Immediacy Index. This research examined 18,526 articles, the complete collection of articles and reviews published by a set of 61 journals on Urology and Nephrology in 2013 and 2014. The findings suggest that Advance Online Publication (AOP) accelerates the citation of articles and affects the JIF and Immediacy Index values. Regarding the JIF values, the comparison between journals with or without AOP showed statistically significant differences (P=0.001, Mann-Whitney U test). The Spearman's correlation between the JIF and the median online-to-print publication delay was not statistically significant. As to the Immediacy Index, a significant Spearman's correlation (rs=0.280, P=0.029) was found regarding the median online-to-print publication delays for journals published in 2014, although no statistically significant correlation was found for those published in 2013. Most journals examined (n=52 out of 61) published their articles in AOP. The analysis also showed different publisher practices: eight journals did not include the online posting dates in the full-text and nine journals published articles showing two different online posting dates--the date provided on the journal website and another provided by Elsevier's Science Direct. These practices suggest the need for transparency and standardization of the AOP dates of scientific articles for calculating bibliometric indicators for journals.
