AI总结:

本文提出在 LLM 回复生成前加入社会情感策略规划模块,并设计结合粗粒度一致性与细粒度社会情感标准的人工评估协议,证明该方法优于端到端生成且公开了代码与标注数据。

摘要:

如今的对话系统已经能够生成令人印象深刻且总体上相关的回复。然而,我们无法观察或控制最先进的大型语言模型(LLM)背后所采用的社会情感策略,这在透明度方面构成问题,并因此影响其在关键应用中的可信度。另一个问题是,当前的自动化指标无法在数据集基准真值之外恰当评估所生成回复的质量。本文提出一种神经架构,该架构在生成回复之前加入一个规划社会情感策略的中间步骤。我们将开源基线 LLM 的性能,与这些相同模型在加入我们的规划模块后产生的输出进行比较。我们还对比了自动化指标得到的输出结果与人工标注者提供的评估结果。我们描述了一种新颖的评估协议,其中包括粗粒度一致性评估,以及依据多种社会和情感标准对回复进行更细粒度的标注。研究表明,先预测一个预期策略标签序列,并使用该序列生成回复,相比直接的端到端生成方案能够取得更好的结果。研究还揭示了当前生成内容评估指标之间的分歧及其局限。标注平台代码和已标注数据均已公开发布,用于未来模型的评估。

英文摘要:

Conversational systems are now capable of producing impressive and generally relevant responses. However, we have no visibility nor control of the socio-emotional strategies behind state-of-the-art Large Language Models (LLMs), which poses a problem in terms of their transparency and thus their trustworthiness for critical applications. Another issue is that current automated metrics are not able to properly evaluate the quality of generated responses beyond the dataset's ground truth. In this paper, we propose a neural architecture that includes an intermediate step in planning socio-emotional strategies before response generation. We compare the performance of open-source baseline LLMs to the outputs of these same models augmented with our planning module. We also contrast the outputs obtained from automated metrics and evaluation results provided by human annotators. We describe a novel evaluation protocol that includes a coarse-grained consistency evaluation, as well as a finer-grained annotation of the responses on various social and emotional criteria. Our study shows that predicting a sequence of expected strategy labels and using this sequence to generate a response yields better results than a direct end-to-end generation scheme. It also highlights the divergences and the limits of current evaluation metrics for generated content. The code for the annotation platform and the annotated data are made publicly available for the evaluation of future models.
