基于知识图谱的云计算技术研究现状与分析

为更清晰地了解国内云计算技术研究现状，以云计算为检索词，选取 CNKI 数据库中云计算领域近 14年（2006-2019 年）共 5 623 篇相关文献为数据源，采用文献计量学方法，借助 CiteSpace 绘制知识图谱。通过对发表时间、文献作者、科研机构、关键词等进行可视化分析得出结论：①该领域文献发表量虽趋于平稳，但仍维持在较高水平；②文献发表以多人合作形式为主，部分研究机构联系密切；③研究热点集中在大数据、虚拟化、物联网、负载均衡、任务调度等领域；④与人工智能结合是未来研究方向。

An Analysis of the Current Situation of Cloud Computing Technology Based on Knowledge Map

In order to have a clearer understanding of the domestic research status of cloud computing technology，the article uses“cloudcomputing”as a search term ，and selected a total of 5623 related literature in the field of cloud computing in the CNKI database for the past 14 years（2006-2019）as the data source，knowledge mapping with the help of CiteSpace by the method of bibliometrics. Through visual analysisof publication time，literature authors，scientific research institutions，keywords，etc.，the following conclusions are drawn：（1）Although the number of publications in this field tends to be stable，it still remains at a high level；（2）The publication is mainly in the form of multi-person cooperation，and some research institutions also maintain close contact；（3）Research hotspots mainly focus on big data，virtualization，Internet of Things，load balancing，task scheduling，etc.；（4）The future research directionwill change to the combination with artificial intelligence.
