Measuring Subjective Persuasion Effectiveness in Symmetric Human-Agent Dialogues

Abstract

To effectively change a user's behavior or attitude, it is crucial to adapt the agent's persuasive behavior and strategy to the user at hand. This requires the agent to assess its persuasive effectiveness as perceived subjectively by the individual user. In this paper, we present an empirical approach for acquiring a multimodal dataset for the task of social sensing of persuasion effectiveness in symmetric human-agent dialogues that base their persuasion on argumentation. To the best of our knowledge, there only exist datasets measuring persuasion effectiveness in asymmetric settings where the user (i.e., the persuadee) is merely a passive recipient of the content without any way to influence the interaction. Contrary to this, the persuadee in our study is an active and speaking participant in the discussion, resulting in a symmetric dialogue where both parties are engaged in mutual exchange. Thus, not only the persuadee's visual modality, as in previous work, but also the persuadee's auditory modality can be considered as a meaningful input. While the present work does not yet include the acquisition of the dataset across different cultures and nationalities, the herein discussed limitations, ethical considerations, and research directions will guide future work. Therewith, this work is laying a foundation for enhancing agent adaptability and designing more effective, culturally aware persuasive interactions in symmetric human-agent communication.
