国内图像检索研究知识图谱分析——基于共词视角

Research of Hotspot of Image Retrieval Theory in China——Based on Co-words Analysis

汇总统计CNKI全文数据库中近十年国内图像检索领域所涉及的关键词,利用SATI 3.2软件统计这些关键词的词频,确定我国图像研究领域使用频率最高的关键词。然后构造共词矩阵、相关矩阵、相异矩阵,并在此基础上利用聚类分析和多维尺度分析多元统计方法对不同的矩阵进行共词分析。最后,对分析结果进行讨论,归纳国内近十年图像检索研究热点。

This paper collected the keywords in the researches of Image Retrieval field published in CNKI fifll- text databases, then use soft SATI 3.2 to get word frequency of these keywords. The highly cited keywords were identified. Construct- ed the co - word matrixes, con - elation matrixes and discriminative matrixes. On the basis of this classification, the paper tried to conduct co- word analysis on different matrixes taking advantage of three multivariate statistic metheds＇--cluster analysis, and multidimensional scaling analysis. At last, it explored the current research status and hotspot of Image Retrieval theory.
