Cross Event Detection and Topic Evolution Mining in cross events for Man Made Disasters in Social Media Streams

Collection of recent CS/SI arXiv papers focused on social-media analytics, LLM-enabled tools, and ad-tech supply-chain vulnerabilities. Key contributions include: CEED, a cross-event detection and topic-evolution framework for disaster-related social streams; PRISM, an LLM-guided semantic clustering method for high-precision topic discovery; AutoVerifier, an agentic LLM-based pipeline for end-to-end technical-claim verification; evaluations of custom vs general-purpose GAI chatbots in science education; LLM-agent social-network simulations; a network-formation game using Katz centrality; and a
