摘要
知识扩散有利于促进科学知识流动、共享和创新。探究我国图书情报学者国际发文的知识扩散情况,对于揭示学科自身发展趋势以及知识扩散特征有着重要的意义。基于文献之间的引证关系,以WEB OF SCIENCE为数据来源,根据知识扩散指标对其发展情况进行定量分析,利用LDA主题模型以及SCIMAT战略坐标图对其扩散特征进行定性分析,结果显示,该学科在不断的寻求发展、融合与创新;在知识扩散的过程中,对外知识扩散集中于14个主题,对美国的知识扩散集中于8个主题,对西班牙和印度的知识扩散分别集中于6个主题。最后,研究发现,对外知识扩散主题与研究热点主题并不重叠。
Knowledge diffusion promotes scientific knowledge to flow,share and innovate.It is of great significance to explore the knowledge diffusion of international publications by Chinese library and information science scholars for revealing the development trend of the discipline and characteristics of knowledge diffusion.Based on literature citation relationship,data in WEB OF SCIENCE are researched by quantitative analysis for development according to knowledge diffusion index,and qualitative analysis for diffusion characteristics by LDA and SCIMAT.The results show that the discipline is constantly seeking for development,integration and innovation.In the process of knowledge diffusion,knowledge diffusion to foreign countries focuses and Idnon 14 themes,to the United States on 8 themes,to Spain and India on 6 themes.And knowledge diffusion does not exist in all the well-developed research themes in China.
