谷歌学术计量(Google Scholar Metrics, GSM)自2012年起也连续每年发布学术出版物的计量指数排名。相比于大家普遍熟悉科睿唯安公司基于Web of Science 数据库公布的《期刊引证报告》(Journal Citation Report, JCR),GSM不仅可以免费检索,而且期刊收录范围远远大于Web of Science。期刊的h5因子比两年影响因子的更难被人为操控,并不会因为多一篇超高被引次数的论文而明显增长,刻意减少发文量也不会对提升h5因子有作用。它可以体现一本期刊的整体综合实力,因此逐渐成为另一个学术出版物影响力评价的参考。
谷歌学术计量(Google Scholar Metrics)主要依据以下6个参数来评价各个领域杂志的影响力:
H指数(h-index或Hirsch index):指在所有发表的论文中有至少h篇论文分别被引用了至少h次,那么这份杂志的H指数就是h。
H核心(h-core):指该杂志最高被引用的h篇论文。
H中值(h-median):指H核心中位数论文的引用次数。
例,某杂志共发表5篇论文,被引用次数分别为17,9,6,3和2次,则该杂志的H指数为3,H核心为17,9,6,H中值为9。
相应地,H5指数(h5-index),H5核心(h5-core)和H5中值(h5-median)的计算基于那些收录在谷歌学术系统中的杂志最近5年的论文数量及各论文被引用的次数。例如,如果某杂志在过去5年内所发表的论文中至少有h篇论文分别被引用了至少h次,那么这份杂志的H5指数就是h。H5核心和H5中值计算方法。
2017年的 h5 因子,统计了期刊近5年中(2012–2016)所发表文章在谷歌学术数据库中截至到2017年6月的引用情况,材料人分别对“化学与材料科学”大类别及“分析化学”、“生物化学”、“陶瓷工程”等13个子类别进行了统计,具体排名如下:
