为探究国际云计算研究知识体系的扩散与演化,本文以WOS平台SSCI、SCI数据库中2601篇云计算研究文献为样本,构建关键词网络并采用文本挖掘、聚类分析等技术将研究主题细分为云计算技术、云系统开发与评估、云服务体系、云计算应用、云计算与新兴技术的融合、云服务安全与隐私等6大主题域,进而结合时序分析方法分析了文献网络的结构和内容的扩散与演化过程。研究表明:云计算知识体系架构正在不断形成和完善,云技术将推动各个行业进入更加智能化和智慧化的发展阶段,未来云应用的重点将集中在政府管理、教育、医疗、能源管理等领域。
In order to explore the diffusion and evolution of the international cloud computing research knowledge system, this paper uses 2601 cloud computing research literature from the WOS platform SSCI and SCI database as a sample to build a keyword network and use text mining and cluster analysis techniques to subdivide the research topics This paper analyzes six main topics of cloud computing technology, cloud system development and evaluation, cloud service system, cloud computing application, integration of cloud computing and emerging technologies, cloud service security and privacy, and then analyzes the structure of the literature network combined with time series analysis The diffusion and evolution of content. The research shows that the architecture of cloud computing knowledge system is constantly being formed and perfected. Cloud technology will push all industries into a more intelligent and intelligent stage of development. In the future, cloud applications will focus on areas such as government administration, education, healthcare and energy management .
