- 将论点组件检测重构为语言生成任务,用指令微调大模型直接输出结果
- 在标准数据集上表现优于现有最先进系统,无需预分割组件
- 适合需要端到端论点分析的研究者和应用开发者
论点组件检测(ACD)是论点挖掘(AM)的核心且最具挑战性的子任务,需同时识别论点片段并分类为主张、前提等类型。现有方法多将其简化为序列标注或分步处理,仍存在局限。本文提出一种基于指令微调大语言模型的新方法,采用紧凑的指令提示,将ACD重新建模为语言生成任务,使模型可直接从原始文本中生成完整论点结构,无需依赖预先分割的组件。在标准基准上的实验表明,该方法性能优于当前最先进系统。据我们所知,这是首次将ACD完全建模为生成任务,凸显了指令微调在复杂论点挖掘问题中的潜力。
原文摘要 · Abstract (English)
Argumentative component detection (ACD) is a core subtask of Argument(ation) Mining (AM) and one of its most challenging aspects, as it requires jointly delimiting argumentative spans and classifying them into components such as claims and premises. While research on this subtask remains relatively limited compared to other AM tasks, most existing approaches formulate it as a simplified sequence labeling problem, component classification, or a pipeline of component segmentation followed by classification. In this paper, we propose a novel approach based on instruction-tuned Large Language Models (LLMs) using compact instruction-based prompts, and reframe ACD as a language generation task, enabling arguments to be identified directly from plain text without relying on pre-segmented components. Experiments on standard benchmarks show that our approach achieves higher performance compared to state-of-the-art systems. To the best of our knowledge, this is one of the first attempts to fully model ACD as a generative task, highlighting the potential of instruction tuning for complex AM problems.
