论文摘要
社会科学和心理学的研究表明，论点的说服力不仅取决于所采用的语言，还取决于来源/沟通者的属性，听众以及论证主张的适当性和力量，鉴于该论点的务实和话语背景。在有说服力的论点的这些特征中，NLP的先前工作在确定论点质量时不会明确研究实用和话语上下文的效果。本文提出了一个新的数据集来启动这一论点的研究：它由涵盖741个有争议的主题的各种论点组成，并包括47,000多个主张。我们进一步提出了预测模型，该模型结合了务实的论证主张的务实和话语上下文，并表明它们的表现优于仅依靠特定于主张的语言特征来预测在特定论点中个人主张对个人主张的感知影响的模型。
Research in the social sciences and psychology has shown that the persuasiveness of an argument depends not only the language employed, but also on attributes of the source/communicator, the audience, and the appropriateness and strength of the argument's claims given the pragmatic and discourse context of the argument. Among these characteristics of persuasive arguments, prior work in NLP does not explicitly investigate the effect of the pragmatic and discourse context when determining argument quality. This paper presents a new dataset to initiate the study of this aspect of argumentation: it consists of a diverse collection of arguments covering 741 controversial topics and comprising over 47,000 claims. We further propose predictive models that incorporate the pragmatic and discourse context of argumentative claims and show that they outperform models that rely only on claim-specific linguistic features for predicting the perceived impact of individual claims within a particular line of argument.
