EmoLASP结合语言模型与回答集编程,在IEMOCAP数据集上提升了情感预测性能,尤其对无微调的仅提示式大语言模型效果显著,可降低相关成本并保证预测一致性。
AI 中文摘要
对话情感识别越来越多地使用语言模型来解决,但这些模型可能不稳定,且微调或使用长对话历史进行提示的成本较高。我们提出EmoLASP,一个结合语言模型与回答集编程(Answer Set Programming,ASP)声明式推理的框架,用于预测对话中的VAD分数(效价-唤醒度-支配度)。在广泛使用的基准数据集IEMOCAP上,针对6个开源大语言模型(LLMs,参数规模3B至120B)和2个预训练语言模型(PLMs,BERT、RoBERTa)的实验显示,EmoLASP与单独使用语言模型相比,预测性能有所提升,即使LLMs/PLMs的提示或输入向量中未提供对话历史,该提升依然存在。仅使用提示的LLMs的提升最大,EmoLASP使用这些模型时无需任何微调。不过,对于已微调的PLMs,当提供对话历史后,推理器带来的增益很小。EmoLASP的LLM管道展示了使用推理方法确保情感预测一致性、降低微调成本以及使用长对话历史进行提示的成本的潜在优势。
英文摘要
Emotion recognition in conversations is increasingly tackled with language models, but these models can be unstable and expensive to fine-tune or to prompt with long dialogue histories. We propose EmoLASP, a framework that combines a language model with declarative reasoning via Answer Set Programming (ASP) to predict VAD scores (Valence-Arousal-Dominance) in conversations. Experiments on a widely used benchmark dataset (IEMOCAP) across six open-source LLMs (3B-120B) and two PLMs (BERT, RoBERTa) show that EmoLASP improves prediction performance compared to using the language model alone, even when the LLMs/PLMs are given no dialogue history in their prompts or input vectors. The gains are largest for prompt-only LLMs, which EmoLASP uses without any fine-tuning. However, for fine-tuned PLMs, the reasoner adds little once dialogue history is available. EmoLASP's LLM pipeline demonstrates the potential advantages of using a reasoning approach to ensure emotion prediction consistency and to reduce both the cost of fine-tuning and the cost of prompting with long dialogue histories.
