| 摘 要： | 以JCR2014年收录的医学信息学领域的7种核心期刊为数据来源, 利用书目共现分析系统——BICOMB软件生成作者共现矩阵, 运用UCINET软件实现高产作者合著网络的可视化, 分析合著网络的密度、平均距离、凝聚子群、核心-边缘结构以及中心度, 揭示国外医学信息学领域合著网络整体结构特性、核心学术团体和高产作者之间的合作情况。研究结果表明, 国外医学信息学领域高产作者合著网络整体信息交流不通畅, 作者合作范围不广泛, 合作模式单一, 缺乏能够连接不同合著群体的桥梁作者。

| Abstract: | This paper took 7 kinds of medical informatics core journals from 2014 JCR as the data samples, used bibliographic items co-occurrence matrix builder BICOMB generating the author co-occurrence matrix, realized the core author co-authorship networks visualization through UCINET software, analyzed the co-authorship networks density, average path length, cohesive subgroups, core-periphery and centralization, revealed the overall network structure characteristics of foreign medical informatics field, the core academic groups and the cooperation between the prolific authors.The result showed that in the co-authorship network of the foreign medical informatics field, the information communication is not smooth, the cooperation between the prolific authors is not widespread, cooperation pattern is single, and lack of the bridge author who can connect different co-authorship group. |
