摘要:

人工标注的数据收集为数据驱动方法提供了领域特定且与任务对齐的监督信号,而要在自然语言处理任务中达到合理性能,需要数量充足的高质量标注资源。然而,人工标注往往难以在时间和预算上扩展规模,尤其在需要领域知识、捕捉细微语义特征及推理步骤的场景中更是如此。本文研究了利用大语言模型开展计算立场检测自动标注的效果。我们通过实验观察到,尽管大语言模型作为人类标注者的替代方案展现出巨大潜力,但其对任务特定指令的敏感性以及固有偏差,给机器标注带来了独特且值得探究的挑战。我们提出了一种多标签与多目标采样策略以优化标注质量。在立场检测基准语料库上的实验结果表明,我们的方法能够显著提升性能和学习效率。

英文摘要:

Data collection from manual labeling provides domain-specific and task-aligned supervision for data-driven approaches, and a critical mass of well-annotated resources is required to achieve reasonable performance in natural language processing tasks. However, manual annotations are often challenging to scale up in terms of time and budget, especially when domain knowledge, capturing subtle semantic features, and reasoning steps are needed. In this paper, we investigate the efficacy of leveraging large language models on automated labeling for computational stance detection. We empirically observe that while large language models show strong potential as an alternative to human annotators, their sensitivity to task-specific instructions and their intrinsic biases pose intriguing yet unique challenges in machine annotation. We introduce a multi-label and multi-target sampling strategy to optimize the annotation quality. Experimental results on the benchmark stance detection corpora show that our method can significantly improve performance and learning efficacy.
