摘要: [目的/意义] 提出领域核心研究主题识别及其演化路径可视化方法,以期为领域主题演化分析研究提供借鉴,对于揭示领域核心主题的演化特征与发展规律具有一定的意义。[方法/过程] 利用LDA模型进行主题识别,结合多维尺度分析和可视化技术将LDA主题识别结果映射到二维空间,识别主题之间的关联关系,确定核心主题、次要主题;利用主题相似度算法探测相邻时期主题之间的关联,提出一种新的可视化展示方法,构建不同类型研究主题的交叉演化路径,以揭示核心主题、次要主题在演化过程中的动态变化。[结果/结论] 以我国医疗健康信息领域为例进行实证研究,研究结果发现,我国医疗健康信息领域核心研究主题主要有电子健康档案、互联网医疗等,其中,健康管理、智慧医疗等核心主题呈现良好的发展演化趋势。

关键词: 核心研究主题, 主题识别方法, 主题演化路径, 可视化方法, 医疗健康信息

Abstract: [Purpose/significance] This paper proposes the identification of the core research topics and their evolution path visualization methods, in order to provide reference for the field subject evolution analysis research, which has certain significance for revealing the evolution characteristics and development laws of the core topics.[Method/process] Using the LDA model for topic recognition and combining multi-dimensional scaling analysis and visualization techniques to map LDA topic recognition results to two-dimensional space. The topic similarity algorithm was used to detect the association between adjacent time topics, a new visual display method was proposed. We constructed cross-evolution paths of different types of research topics to reveal the dynamic changes of core topics and secondary topics in the evolution process.[Result/conclusion] Taking the medical health information field in China as an example, the research results show that the core research topics in the field of medical and health information in China mainly include electronic health records and Internet medical treatment. Among them, core themes such as health management and smart medical treatment show a good development trend.

Key words: core research topics, topic recognition method, topic evolution path, visualization, medical health information
