AI总结:

本文构建Roadrunner-Hedge语料库,比较微调BERT与GPT-4o、LLaMA-3的零样本和少样本提示在自发叙事模糊限制语检测上的表现,发现微调BERT最优,并通过人在回路方法改进标注以指导未来研究。

摘要:

模糊限制语允许说话者将话语标记为临时性的,无论是为了表示非典型性或“模糊性”,表明对话语缺乏承诺,将陈述的责任归于他人,邀请对话伙伴提供意见,还是为了面子管理需求而软化批评性反馈。在此,我们聚焦于一个经过实验参数化的语料库中的模糊限制语,该语料库包含63段Roadrunner卡通叙事,由21位说话者从记忆中为在场的受话者自发产生,并转写为文本(Galati和Brennan, 2010)。我们创建了一个由人工编码者标注的模糊限制语金标准(Roadrunner-Hedge语料库),并比较了三种基于大语言模型的模糊限制语检测方法:微调BERT,以及使用GPT-4o和LLaMA-3进行零样本和少样本提示。表现最好的方法是微调后的BERT模型,其次是少样本GPT-4o。在对表现最好的方法进行错误分析后,我们使用了一种人在回路的大语言模型方法来改进金标准编码,并突出那些在语言学上有趣且具有歧义的模糊限制语案例,以指导未来研究。这是我们研究计划的第一步,该计划旨在训练大语言模型在对话中恰当且有意义地解释和生成附带信号。

英文摘要:

Hedges allow speakers to mark utterances as provisional, whether to signal non-prototypicality or "fuzziness", to indicate a lack of commitment to an utterance, to attribute responsibility for a statement to someone else, to invite input from a partner, or to soften critical feedback in the service of face-management needs. Here we focus on hedges in an experimentally parameterized corpus of 63 Roadrunner cartoon narratives spontaneously produced from memory by 21 speakers for co-present addressees, transcribed to text (Galati and Brennan, 2010). We created a gold standard of hedges annotated by human coders (the Roadrunner-Hedge corpus) and compared three LLM-based approaches for hedge detection: fine-tuning BERT, and zero and few-shot prompting with GPT-4o and LLaMA-3. The best-performing approach was a fine-tuned BERT model, followed by few-shot GPT-4o. After an error analysis on the top performing approaches, we used an LLM-in-the-Loop approach to improve the gold standard coding, as well as to highlight cases in which hedges are ambiguous in linguistically interesting ways that will guide future research. This is the first step in our research program to train LLMs to interpret and generate collateral signals appropriately and meaningfully in conversation.
