     近日,我院陈仕吉教授、宋艳辉教授、舒非教授与加拿大蒙特利尔大学信息学教授Vincent Larivière合作论文《Interdisciplinarity and impact: the effects of the citation time window》发表于国际计量学顶级期刊《Scientometrics》(SSCI,影响因子3.238)。

     该研究探讨了引用时间窗、跨学科性和学术影响力之间的关系,研究表明引用时间窗是跨学科研究学术影响力的一个重要因素,因此,评估跨学科研究的科学影响需要足够长的引用时间窗。具体来说,对跨学科的单属性指标而言,Variety至少需要4年的引用时间窗,而Balance和Disparity需要更长的引用时间窗(分别13年和11年)。引用时间窗的长度可能会造成截然不同的研究结论。对跨学科性的综合指标而言,RS、LCDiv和DIV三种指标对学科影响力的影响表现出一致的趋势,都至少需要5年的引用时间窗。
 
     文章摘要ABSTRACT
     The relationship between interdisciplinarity and citation impact is affected by many factors, and the citation time window is a crucial factor. Our study examines the effect of the citation time window on the relationship between interdisciplinarity and scientific impact. All journal articles published in 2006 in Web of Science (WoS) are considered. The relationship between interdisciplinarity and scientific impact is explored by conducting a year-by-year negative binomial regression analysis with different interdisciplinarity indicators. Three diversity single-property indicators (namely variety, balance, and disparity) and three typical composite interdisciplinarity indicators (Rao-Stirling index (RS), Leinster–Cobbold diversity indices (LCDiv), and DIV) are used in this study. The results show that evaluating the scientific impact of interdisciplinarity requires a sufficiently long citation time window. However, the length of the citation time window is different for different interdisciplinarity indicators. A 4-year citation time window is necessary when the variety indicator is used, whereas balance and disparity require at least 11-year and 13-year citation time windows, respectively. The citation time window is the same (at least 5 years) for the three composite interdisciplinarity indicators (RS, LCDiv, and DIV). The recommended length of the citation time window is based only on this study and may be affected by the data set, regression model, and discipline classification system.
