NTS-CoT: Mitigating Hallucinations in LLM-based News Timeline Summarization with Chain-of-Thought Reasoning

In three linesNTS-CoT, a Chain-of-Thought framework, mitigates hallucinations in LLM-based timeline summarization. Three modules (Element-CoT, Date Selection, Causal-CoT) capture essential news elements, select timestamps, and infer causal relationships. Evaluation on three TLS benchmarks shows measurable improvements over baselines.
