基于社交媒体数据的城市内涝主题挖掘综述

随着全球气候变暖情况的严重,城市内涝现象频发,对人们生活和城市运行产生严重影响。通过社交媒体对数据进行采集和挖掘,解决传统的灾害信息收集效率低、全域覆盖困难等问题,在灾害应急管理中发挥着关键作用。围绕对社交媒体内涝数据的采集、主题挖掘的关键技术方法,梳理国内外相关文献,进行必要的评述分析。最后,对现有研究存在的问题和未来发展趋势进行总结与展望。旨在为城市内涝数据采集、主题挖掘研究提供理论和方法支持,也为城市内涝灾害分析和管理提供参考。

With the serious global warming,urban waterlogging has occurred frequently,which has had a serious impact on people's lives and urban operations.Collecting and mining data through social media solves the problems of low efficiency and difficulty in full coverage of traditional disaster information collection,and plays a key role in disaster emergency management.Focusing on the key technical methods of collecting waterlogging data and mining topics on social media,this paper combs through relevant domestic and foreign literature and conducts necessary reviews and analyses.Finally,the problems existing in existing research and future development trends are summarized and prospected.It aims to provide theoretical and methodological support for urban waterlogging data collection and topic mining research,and also provide reference for urban waterlogging disaster analysis and management.
