基于知识图谱的石斛研究可视化分析与构建

Visualized Analysis and Construction of Dendrobium Study Based on Knowledge Graph

石斛作为一种中药材因具有良好的药用价值和市场价值而被广泛地研究与应用.本研究主要基于知识图谱的石斛研究可视化分析与构建,预测其未来发展趋势,为后续研究和临床应用提供重要参考依据.研究选取中国知网数据库中近20年有关石斛研究的文献,利用Citespace软件对作者、机构和关键词进行可视化分析,结合半监督训练等算法来实现石斛领域的知识图谱构建.实验结果表明:1)作者与机构存在较强地域性,合作关系较为密切;2)研究重点主要围绕提取工艺、临床应用和数据挖掘等方面,体现了研究的广度和深度;3)研究热点变化与市场需求联系紧密;4)构建的知识图谱与石斛研究领域结果相符合.

Dendrobium has been widely researched and used as a kind of Chinese medicinal material due to its good medicinal value and market value.Analysis and construction of visualized dendrobium study based on Knowledge Graph has been completed in this research,which can predict future development trends and provide important reference for follow-up scientific research and clinical application.The references of Dendrobium research in the recent two decades from the China National Knowledge Infrastructure(CNKI)database were selected as the research data.The visualized analysis of authors,institutions and keywords can be done by Citespace software.The construction of knowledge graph in the dendrobium field can be realized by Semi-supervised training algorithm,etc.The experimental results can be shown as follows.1)Authors and institutions have strong regionality and close cooperation.2)The research mainly focuses on extraction technology,clinical application and data mining,which reflects the breadth and depth of research.3)Changes in research hotspots are closely related to market demand.4)The constructed knowledge graph is consistent with the results of the dendrobium research field.
