Tdnguyen at CQs-Gen 2025: Adapt Large Language Models with Multi-Step Reasoning for Critical Questions Generation

AbstractThis paper explores the generation of Critical Questions (CQs) from argumentative texts using multi-step reasoning techniques, specifically Chain-of-Thoughts (CoT) and Tree-of-Thoughts (ToT) prompting frameworks. CQs are essential for enhancing critical thinking and improving decision-making across various domains. Despite the promise of Large Language Models (LLMs) in this task, generating contextually relevant and logically sound questions remains a challenge. Our experiments show that CoT-based prompting strategies, including Zero-shot and One-shot methods, significantly outperform baseline models in generating high-quality CQs. While ToT prompting offers a more flexible reasoning structure, it was less effective than CoT in this task. We suggest exploring more advanced or computationally intense multi-step reasoning techniques, as well as alternative tree structures for the ToT framework, to further improve CQs-Gen systems.
