This invention discloses a method and system for regional and national hotspot mining and briefing generation based on complex networks and large language models, belonging to the field of natural language processing and public opinion analysis technology. The method includes: collecting, cleaning, deduplicating, and sorting multilingual public opinion data; constructing a news dissemination network based on temporal semantic similarity and using connected component algorithms to discover hotspot communities; performing quality assessment and topic consistency optimization on the communities, and selecting representative texts using an improved PageRank algorithm; and automatically generating structured briefings including event summaries, knowledge graphs, news rewriting and commentary, and hotspot extensions by combining preset prompt templates with a generative large language model. This invention can effectively capture the dynamic evolution of multilingual public opinion, improve the accuracy and completeness of hotspot event mining, achieve full automation from data collection to report generation, and significantly improve the efficiency and depth of regional and national public opinion analysis.
