论文部分内容阅读
通过中国知网学术文献总库和中国引文数据库,获取《眼科新进展》、《眼科研究》、《眼科》、《临床眼科杂志》、《中国实用眼科杂志》等5种综合性眼科杂志2m5年发表的论文在2005～2009年各年度被引量和下载量,以确定医学论文丁载量和被引量的关系及下载量的峰值年代。获取2000年发表的论文在2000～2009年各年度的被引量,以确定医学论文被引量的峰值年代。结果显示,论文下载量和被引量呈高度正相关(r=4.91,P=0.000)。1622篇论文中,有50篇(3.08%)论文表现出量引背离现象。论文被引用峰值年代在论文发表后的第7～8年,而论文下载量的峰值年代在论文发表后的第2年。因此认为,在学术评价过程中,下载量指标比被引量指标具有更强的时效性。
Through the China National Knowledge Infrastructure and the China Citation Database, we get 2 kinds of comprehensive 5m ophthalmic journals, such as New Progress in Ophthalmology, Ophthalmology, Ophthalmology, Clinical Ophthalmology, and Clinical Ophthalmology in China. The published papers were quoted and downloaded in each of the years 2005-2009 to determine the peak age of the relationship between downloads and quotations and the downloads of medical papers. Obtain quotations for 2000 papers published in 2000 and 2009 to determine the peak age of citations for medical papers. The results showed that there was a high degree of positive correlation between the number of essay downloads and the quoted quantity (r = 4.91, P = 0.000). Out of 1622 papers, 50 (3.08%) of the papers showed a volume-dependent divergence. The essay is quoted in the peak years from the 7th to the 8th after the publication of the essay, while the peak of the essay downloads is the second year after the essay was published. Therefore, it is considered that in the process of academic evaluation, the download index is more time-efficient than the quoted index.
