在英国和澳大利亚，最近都有一个使用引文分析来评估个人研究的举措。特别是，未来的英国研究卓越框架（REF），建议使用引用数据在最近发表的文章的研究评估前一年的评估。为了应对这一举措，本研究在每篇文章的层面开发了一个指标，当标准化后，可以补充同行评审。新的混合指标是两个常用指标的加权和：文章在引用窗口中的引用总数，以及文章发表的期刊的影响因子。这项研究将这个新指标与文章在较长引用窗口中的引用总数（文章影响力的标准指标）进行了比较。对于0年或1年的引文窗口，简化加权和与长期引文的相关性显著高于文章引文标准指标与长期引文的相关性。此外，对于长达3年的引用窗口，引用的标准指标与出版月份显着相关，因为年初发表的文章平均被引用率高于年末发表的文章。相比之下，简化加权和对年初发表的文章的倾斜程度要比标准指标小得多。(C)2010爱思唯尔有限公司版权所有。
In both the UK and Australia there has been a recent move to use citation analysis in the evaluation of the research of individuals. In particular, the future UK Research Excellence Framework (REF), proposes using citation data in the research evaluation of articles published as recently as the year prior to the evaluation. In response to this move, this research develops an indicator at the level of individual articles that, when normalized, can supplement peer review. The new hybrid indicator is the weighted sum of two indicators in common usage: the article's total number of citations in a citation window, and the Impact Factor of the journal in which the article was published. This research compares this new indicator with the article's total number of citations in a longer citation window (the standard indicator of article impact). For citation windows of 0 or 1 years, the correlation of the simplified weighted sum with long-term citation is substantially higher than the correlation of the standard indicator of article citation with long-term citation. Moreover, for citation windows of as long as 3 years the standard indicator of citation correlates significantly with the month of publication, in that articles published earlier in the year are on average more highly cited than those published later in the year. By contrast, the skewing of the simplified weighted sum towards articles published early in the year is considerably less than that of the standard indicator. (C) 2010 Elsevier Ltd.
