根据影响因子的定义和计算公式,利用Web of Science数据库的引证分析功能,对选择的28种眼科学SCI来源期刊不同引证时间窗口的影响因子:包括2年影响因子、3年影响因子、4年影响因子、5年影响因子和6年影响因子进行了计算和比较,并与同行评议得分做了相关分析。结果表明,不同引证时间窗口影响因子值不同,但用于期刊评价具有极高的相关度。通过与同行评议得分比较,眼科学期刊3IF和4IF较为理想。3年和4年引证时间窗口与眼科学期刊文献被引高峰年代高度一致。
According to the definition and calculation formula of influencing factor, we use the citation analysis function of Web of Science database to analyze the influencing factors of different citation time windows of 28 selected ophthalmology SCI source journals: 2-year impact factor, 3-year impact factor, 4 years Impact factors, five-year impact factors and six-year impact factors were calculated and compared with peer-reviewed scores were analyzed. The results show that different citation time windows affect the value of different factors, but for the evaluation of the journal has a very high correlation. Ophthalmology journals 3IF and 4IF are better than peer review scores. The three-year and four-year citation time windows are highly consistent with the citing ophthalmic journal literature.
