摘要:

当进行辩论性话语时,熟练的人类辩论者根据听众的信念调整主张,以构建有效的论点。最近,计算论证领域见证了广泛的努力,以解决自动生成的论点。然而,现有的方法不执行任何观众特定的适应。在这项工作中,我们的目标是通过研究基于信念的索赔生成任务来弥合这一差距:给定一个有争议的话题和一组信念,生成一个针对信念的论证性索赔。为了解决这一任务,我们通过人们对有争议的话题的立场来模拟他们先前的信念,并扩展最先进的文本生成模型来生成以信念为条件的索赔。我们的自动评估证实了我们的方法能够适应一组给定的信念的要求。在手动研究中,我们还根据信息量及其被具有相应信念的人说出的可能性来评估生成的声明。我们的研究结果揭示了基于他们的立场建模用户的信念的局限性,但展示了编码的信念到议论文的潜力,奠定了基础,为未来的探索观众的范围。

英文摘要:

When engaging in argumentative discourse, skilled human debaters tailor claims to the beliefs of the audience, to construct effective arguments. Recently, the field of computational argumentation witnessed extensive effort to address the automatic generation of arguments. However, existing approaches do not perform any audience-specific adaptation. In this work, we aim to bridge this gap by studying the task of belief-based claim generation: Given a controversial topic and a set of beliefs, generate an argumentative claim tailored to the beliefs. To tackle this task, we model the people's prior beliefs through their stances on controversial topics and extend state-of-the-art text generation models to generate claims conditioned on the beliefs. Our automatic evaluation confirms the ability of our approach to adapt claims to a set of given beliefs. In a manual study, we additionally evaluate the generated claims in terms of informativeness and their likelihood to be uttered by someone with a respective belief. Our results reveal the limitations of modeling users' beliefs based on their stances, but demonstrate the potential of encoding beliefs into argumentative texts, laying the ground for future exploration of audience reach.
