基于引用网络的医学主题领域跨学科知识交流研究

Study on Interdisciplinary Knowledge Exchange in Medical Subject Field Based on Citation Network

基于学科引用网络揭示医学主题研究领域的跨学科知识交流现状。具体流程包括根据文献间的引用关系构建领域学科网络,利用社会网络分析的中心度指标识别领域内的关键学科,并以核酸疫苗主题领域为实证,结合关键词聚类分析该领域核心学科跨学科引用的知识内容。

Based on disciplinary citation network,the paper reveals the current situation of interdisciplinary knowledge exchange in medical subject research field.Specifically,the discipline network is constructed according to the citation relationship between papers,and the key disciplines in the field are identified by using the centrality index of Social Network Analysis(SNA).The nucleic acid vaccine subject is taken as an example,and the knowledge content of interdisciplinary citation of the core disciplines in the field is analyzed by keyword clustering.
