以能源领域期刊为例,根据JCR报告中关于学科主题的分类,提出了一种新的视角,通过建立期刊的学科主题共现矩阵,利用2-模网络分析方法对期刊进行分类,清晰地展示出了期刊的跨领域类别,进而分析了期刊之间的知识交叉结构关系以及不同学科主题在能源研究领域的地位。这种方法避免了基于引文分析的期刊分类方法因期刊本身载文量及其引文数量变化带来的影响。
Taking journals in the energy field as an example, this paper proposes a new perspective based on the classification of subject topics in the JCR report. By establishing a co-occurrence matrix of subject topics and using a 2-modal network analysis method to classify the journals and clearly display Then, the paper has also published the interdisciplinary categories of journals, and then analyzed the interdisciplinary knowledge structure of journals and the status of different subject topics in the field of energy research. This method avoids the influence of citation analysis on how the journal classification method changes due to the periodical itself and the number of citations.
