有关用户对论证的主观意见的信息对于论证系统至关重要,以便呈现适当的内容并使其行为适应个体用户。然而,要求对所讨论的论点进行明确的反馈通常是不切实际的,并且可能会阻碍互动。为了解决这个问题,我们研究了如何自动识别用户对通过社交信号中的虚拟化身提出的论点的意见。我们关注两种不同的用户意见类别(令人信服和有趣)和两种不同类型的社交信号(面部表情和眼球运动)。该识别被视为监督学习问题,并使用先前工作中讨论的参数搜索评估数据来实现。将整体性能与对所收集数据的子集进行的人工注释进行比较。结果表明,机器学习在这两个识别任务中的表现与人类的表现相似。
Information about a subjective user opinion towards an argument is crucial for argumentative systems in order to present appropriate content and adapt their behaviour to the individual user. However, requesting explicit feedback regarding the discussed arguments is often impractical and can hinder the interaction. To address this issue, we investigate the automatic recognition of user opinions towards arguments that are presented by means of a virtual avatar from social signals. We focus on two different user opinion categories (convincingandinteresting) and two different types of social signals (facial expressions and eye movement). The recognition is addressed as a supervised learning problem and realized using the argument search evaluation data discussed in previous work. The overall performance is compared to a human annotation on a subset of the collected data. The results show that the machine learning performance is similar to human performance in both recognition tasks.
