Abstract: Based on visual analysis method, the authors analyzed the emergence background and history of cloud computing research. Firstly, the core authors group of cloud computing research area was determined, and a co-word network was constructed using published literature bibliographic data of these authors in the last ten years. Then the community structure sampling algorithm and G-N clustering algorithm were introduced to analyze the overall distribution of the research field. Through counting the membership degree of a keyword to specific research groups, the authors made a comparative analysis on core groups’ research features. Finally, the migration path of core group’s research interest after and before entering this field was analyzed, and the domestic development of cloud computing was divided into several basic stages.

Key words: cloud computing, core author, co-word network, G-N clustering algorithm, membership degree, evolution path

摘要： 基于海量数据可视化分析方法, 对云计算的出现背景和发展历史进行计量分析。首先确定一批云计算研究领域核心作者, 基于这一作者群近十余年来发表文献的题录数据, 构建云计算核心作者群的研究共词网络。引入社群结构抽样算法和G-N聚类算法, 对领域研究总体分布情况进行分析。引入概念团队隶属度算法, 对重点学科团队研究特色进行比较分析。从时间维度分析云计算核心作者群进入该领域前后研究兴趣点的迁移轨迹, 并对国内云计算领域演化发展的基本阶段进行划分。
