社交媒体数据分析在台风灾害管理中的应用潜力探究——以台风"杜苏芮"对福建省的影响为例
Application Potential of Social Media Data Analytics in Typhoon Disaster Management:Taking the Impact of Typhoon Doksuri on Fujian Province as an Example
摘要
Abstract
The rapid growth of social media has introduced new concepts and technical approaches for disaster management.This paper reviews the characteristics of social media data and its application potential in disaster management research,providing a new research perspective for the field of disaster management.Taking the impact of Typhoon Doksuri in Fujian Province in 2023 as a case study,this research employs Latent Dirichlet Allocation(LDA)topic modeling to analyze the practical application effectiveness of social media data at different stages of disaster management from three perspectives:the spatiotemporal distribution of posts,trend analysis of different types of entities,and evolution of topic content.These findings indicate that the synchronous relationship between the popularity of related topics on Weibo and the impact of a disaster event confirms the effective application of social media data in disaster management.By monitoring the dynamics of information dissemination on social media,we can determine the occurrence status and impact scope of disasters in real time.During disasters,different user types have different foci.Individual users tend to focus more on the restoration of living facilities and the supply of relief materials,whereas organizational users concentrate on disseminating information about disasters and emergency response measures.The information provided by different types of users can provide a more comprehensive and diversified perspective on disaster perceptions for disaster management.Analysis of the evolution of topic content can reflect the evolution of emergency response dynamics and public attention needs in different cities at different stages of disaster management,thereby developing more practical emergency response strategies.Through the mining and analysis of social media data,this study recognizes the entire process of disaster occurrence from the perspective of social media data,thereby enriching the relevant theoretical and empirical research.Future research could be conducted from perspectives such as utilizing other multisource data,integrating machine learning and deep learning technologies to enhance the accuracy of topic information extraction,and exploring the application of social media data to post-disaster emergency rescue and infrastructure support.关键词
