摘要
以我国网络计量学期刊论文的题录和引文数据为基础,应用Gephi分别生成了期刊-学科-时序网络图和特征词聚类-时序网络图,并对其进行逐一分析。期刊-学科-时序网络图横轴显示某种期刊涉足网络计量学领域的最早发文年份,纵轴显示涉足网络计量学的四种期刊类型,分别是图书情报学类、计算机软件类、高校学报类以及其他学科类期刊,揭示该学科领域内部知识扩散的宏观特征;特征词聚类-时序网络图则显示网络计量学研究主要有三个区域:网络计量理论与方法、网络计量实证应用以及网络计量算法与技术,并对这三个区域进行时序分析,揭示其内部知识扩散的微观特征。
Based on the title list and the citation data of the journal articles in Webometrics in China, the present paper employs Gephi to make a journal subject sequence network diagram and a feature-words-clustering sequence network diagram and then analyzes them respectively. The former diagram reveals the macroscopic features of the internal knowledge diffusion in the discipline of Webometrics, with its horizontal axis showing the earliest year in which a journal published articles in Webometrics and its vertical axis indicating the four types of journals which have published articles in Webometrics, namely journals of library and information science, journals of computer software, university journals and other journals.The latter diagram reveals the microscopic features of the internal knowledge diffusion by demonstrating the three main fields in Webometrics, i. e. Webometrical theories and methods, empirical application of Webometrics and Webometrical algorithm and technology.
