How Large Language Models Empower the Analysis of Online Public Engagement for Mega Infrastructure Projects: Cases in Hong Kong
研究利用大型语言模型解析香港九个大型基础设施项目的社交媒体数据，识别关键影响者并分析公众参与动态，为决策者优化在线沟通策略提供支持。
Mega infrastructure projects (MIPs) have profound societal impacts, and public engagement plays a crucial role in their success. The rise of social media enables the dynamic analysis of public opinions, aiding decision-makers in addressing public concerns. This study introduces a networking, parsing, retrieval, and mapping approach that innovatively leverages large language models (LLMs) for massive text parsing and social network analysis. Using data from Hong Kong's nine MIP topics, this study identifies influencers and examines public and influencer engagement across project lifecycles. The findings and constructed managerial maps reveal the hidden dynamics of involvement and interaction across different project event types, enabling a prioritized management method. The novel LLM-driven framework offers decision-makers actionable insights to comprehensively optimize online public communication and engagement strategies for MIPs.
