近10年国内物联网研究热点分析

Research of Hotspot of Internet of Things Theory in China

通过对中国知网上近10年来物联网文献进行检索,利用词频统计软件统计物联网高频关键词,归纳出国内物联网研究热点关键词,利用共词分析法和多维尺度分析统计方法对结果进行讨论,分析关键词之间的专业知识联系,最后总结我国物联网研究热点主要集中在概念、体系架构、关键技术和应用领域等4个方面。

We collect the keywords in the researches of internet of things field published in CNKI full-text databases,then use soft SATI 3. 1 to get word frequency of these keywords. The highly cited keywords are identified. On the basis of this classification,the paper tries to conduct co-word analysis on different matrixes taking advantage of three multivariate statistic methods—word frequency,and multidimensional scaling analysis. At last we explore the current research status and hotspot of internet of things theory.
