AI总结:

本文通过构建包含 409 个事实驱动型问题和 7,534 条人类评分回答的 Reddit 数据集,研究大语言模型建模多样化人类回答的能力,发现其对高评分回答的建模效果显著优于低评分回答,并为未来研究提出方向。

摘要:

大语言模型(LLMs)已被证明能够在在线话语语境中正确回答问题。然而,利用大语言模型来建模人类对事实驱动型社交媒体问题的类人回答这一研究仍处于探索不足的状态。在这项工作中,我们研究了大语言模型如何建模人类对若干主题特定 Reddit 社区(即 subreddits)中提出的事实驱动型问题所给出的多样化回答。我们收集并发布了一个数据集,其中包含来自 15 个 r/Ask{Topic} 社区的 409 个事实驱动型问题和 7,534 条多样化、经人类评分的回答,这些社区涵盖 3 个类别:职业、社会身份和地理位置。我们发现,与评分较低的人类回答相比,大语言模型在建模此类问题的高评分人类回答方面表现得明显更好。基于我们的初步发现,我们提出了未来研究的若干方向。

英文摘要:

Large language models (LLMs) have been shown to be proficient in correctly answering questions in the context of online discourse. However, the study of using LLMs to model human-like answers to fact-driven social media questions is still under-explored. In this work, we investigate how LLMs model the wide variety of human answers to fact-driven questions posed on several topic-specific Reddit communities, or subreddits. We collect and release a dataset of 409 fact-driven questions and 7,534 diverse, human-rated answers from 15 r/Ask{Topic} communities across 3 categories: profession, social identity, and geographic location. We find that LLMs are considerably better at modeling highly-rated human answers to such questions, as opposed to poorly-rated human answers. We present several directions for future research based on our initial findings.
