基于CiteSpace的地铁安全研究知识图谱及可视化分析

Knowledge Map and Visualization Analysis of Metro Safety Research Based on CiteSpace

为揭示地铁安全研究领域的知识结构和研究热点,本研究以中国知网数据库2005-2019年所收录的与地铁安全研究相关的1786篇文献为研究对象,基于知识图谱的相关理论,运用文献可视化软件CiteSpace绘制地铁安全相关研究的知识图谱,并进一步开展了发展态势分析、合作网络分析、关键词共现分析和研究热点分析。研究表明:地铁安全研究的发文量从2007年开始迅速增长;可视化知识图谱显示核心作者群和有关研究机构呈现出来的状态较为分散;不同的研究群体和研究机构之间呈现出了水平差异性;研究的趋势与热点主要集中在风险分析、风险评估、风险控制、安全风险管理、数值模拟、火灾疏散、BIM、信息技术等方面。最后,对地铁安全研究提出了针对性建议。

In order to reveal the knowledge structure and research hotspots of metro safety research field,1786 articles related to metro safety research are selected as the research object from the CNKI(China National Knowledge Infrastructure)database from 2005 to 2019,based on the related theory of knowledge map,and the knowledge map of metro safety related research is drawn by using the software CiteSpace,the developing situation analysis,cooperation network analysis,keyword co-occurrence analysis and research hotspot analysis are carried out.The results show that:the amount of papers issued for metro safety research has increased rapidly since 2007;the visual knowledge map shows that the core author group and the research hotspots are relatively scattered;different research groups and research institutions show research level differences;research trends and hotspots are mainly concentrated in risk analysis,risk assessment,risk control,security risk management,numerical simulation,fire evacuation,BIM,information technology,etc.In the end,targeted suggestions are proposed for metro safety research.
