本文应用布拉德福区域分析法对国内医学期刊进行层次划分,并依据各层次期刊的影响因子(IF)均值时分布于相应层次的论文和引文赋予不同的分值,指出所划分的各层次医学期刊IF的分布基本符合布拉德福定律中的离散现象,认为所进行的层次划分和赋分方法可应用于对期刊所载论文及引文质量进行评估。
In this paper, we use Bradford regional analysis to classify domestic medical journals and assign different scores according to the mean of IF of the journals at different levels to distribute the papers and citations at the corresponding level. The distribution of IF in medical journals basically conforms to the discrete phenomenon in Bradford’s law, and the hierarchy division and assignment method can be applied to evaluate the quality of papers and citations in journals.
