摘要
以中国知网CNKI为数据源,获取了辽宁省40所高校图书馆在2000-2009年发表论文和论文被引用情况。根据评价指标的定义,分别计算各高校图书馆相应的h指数、g指数和hg指数,对各指数排序进行比较,并利用SPSS统计软件对高校图书馆各种评价指标进行统计分析。研究结果显示,用hg指数评价高校图书馆科研影响力更接近于真实情况,说明hg指数弱化了h指数和g指数各自的侧重,兼顾了论文数量和高被引论文被引频次对评价对象科研影响力的贡献,评价结果更细致、合理和公正。
Papers published by 40 academic libraries in Liaoning Province from 2000 to 2009 and their citations were searched from CNKI. Their h index, g index and hg index were calculated according to the definitions of the 3 assessment indexes, ranked and compared. The 3 indexes for assessment of scientific research influence of academic library were analyzed using the SPSS software, which showed that the scientific research influence of academic library was closer to its real situation when it was assessed using the hg index, indicating that the hg index can weaken the h index and g index, and display the contribution of the number of papers and the citation frequency of highly-cited papers to the scientific research influence of the assessed subjects with the assessment being more detailed, rational and just.
