| 摘 要： | 目的/意义]探讨被引频次位置指标在科技期刊评价中的作用,确定合适时间窗口的最优位置指标。方法/过程]从Web of Science数据库中选取符合条件的14种眼科期刊作为研究对象,分别计算各期刊2014年度不同位置指标,包括2年、5年、8年和10年引证时间窗口(citation time window,CTW)的h指数(h2、h5、h8和h10)、累计h指数(a-h2、a-h5、a-h8和a-h10)以及相对应的期刊2014年度被引频次百分位数位置(percentage rank position,PRP)指标(Top1%、Top5%、Top10%、Top25%Top50%)和累计PRP指标(a-Top1%、a-Top5%、a-Top10%、a-Top25%和a-Top50%)。比较影响因子、不同CTW位置指标与期刊问卷调查评分的相关度,确定不同位置指标应用于期刊评价的效果。结果/结论]合理的位置指标在期刊影响力评价中优于影响因子和5年影响因子,累计被引频次位置指标普遍优于年度指标,2年CTW的h指数优于其他CTW的h指数,5年CTW的a-h2、h2,5年和8年CTW的a-Top50%和Top50%与影响因子和5年影响因子相比具有更理想的期刊评价效果。

| Abstract: | Purpose/significance] The paper aims to probe into the roles of citation position indicators used in journal evaluation, and to define the best suitable time window for citation position indicatorBFQ].BF] Method/process] kinds of qualified ophthalmology journals were selected from Web of Science database in this study. The different positional indicators in 2014 were calculated for each journal, including 2-year, 5-year, 8-year and 10-year citation time window h-index (h2, h5, h8 and h10), and accumulative h-index (a-h2, a-h5, a-h8 and a-h10), and the corresponding 2014 indicators of journal citation’s Percentage Rank position(PRP), including Top 1%, Top 5%, Top 10%, Top 25% Top 50%, and accumulative PRP(a-PRP) index (a-Top 1%, a-Top 5%, a-Top 10%, a-Top 25% and a-Top 50%). The correlation level of impact factor, positional indicators in different citation time window with questionnaire score were analyzed, and the effects of different positional indicators for journal evaluation were detected. Result/conclusion] The results show that reasonable position indicators are better than impact factor and 5-year impact factor in journal impact assessment, the accumulative citations position indicators generally better than the annual indicators, h index of 2-year citation time window than that of other citation time window. The a-h2, h2 of 5-year citation time window, and a-Top 50%, Top 50% of 5-year and 8-year citation time window have more desirable effect in journal evaluation compared with the impact factor and 5-year impact factor. |
