Research on Co－occurrence Network of Keywords Set by R
摘要
Abstract
[ Purpose/Significance] The paper proposed the concept of keyword set, explored R language program?ming to achieve the creation and visualization of keyword set co－occurrence network, for further research on keyword set－based data mining and knowledge discovery to provide a more general way and method.[ Methods/Process] Using R lan?guage programming technology and igraph contribution package, the paper designed the key word set co－occurrence network creation and visualization function, and analyzed the published data of 18 CSSCI source journals in the field of graph sci?ence.[Results/Conclusion] The centrality and other characteristic parameters of the co－occurrence network of keyword set were calculated, and the co－occurrence network graph of keyword set was drawn. The research showed that the co－occur?rence network of keyword sets revealed the distribution, clustering and relationship characteristics of keyword sets, keyword sets could more intuitively reveal the theme content and its relationship of the analysis object, and the construction and characterization of its characteristic parameters were worthy of systematic and in－depth study.关键词
