Chain-of-Thought Matters: Improving Long-Context Language Models with Reasoning Path Supervision

EMNLP 2025

Recent advances in Large Language Models (LLMs) have highlighted the challenge of handling long-context tasks, where models need to reason over extensive input contexts to aggregate target information. While Chain-of-Thought (CoT) prompting has shown promise for multi-step reasoning, its effectivene

FaGANet: An Evidence-Based Fact-Checking Model with Integrated Encoder Leveraging Contextual Information

COLING 2024main

In the face of the rapidly growing spread of false and misleading information in the real world, manual evidence-based fact-checking efforts become increasingly challenging and time-consuming. In order to tackle this issue, we propose FaGANet, an automated and accurate fact-checking model that lever…
