What changed your mind : the roles of dynamic topics and discourse in argumentation process

In our world with full of uncertainty, debates and argumentation contribute to the progress of science and society. Despite of the in- creasing attention to characterize human arguments, most progress made so far focus on the debate outcome, largely ignoring the dynamic patterns in argumentation processes. This paper presents a study that automatically analyzes the key factors in argument persuasiveness, beyond simply predicting who will persuade whom. Specifically, we propose a novel neural model that is able to dynamically track the changes of latent topics and discourse in argumentative conversations, allowing the investigation of their roles in influencing the outcomes of persuasion. Extensive experiments have been conducted on argumentative conversations on both social media and supreme court. The results show that our model outperforms state-of-the-art models in identifying persuasive arguments via explicitly exploring dynamic factors of topic and discourse. We further analyze the effects of topics and discourse on persuasiveness, and find that they are both useful -- topics provide concrete evidence while superior discourse styles may bias participants, especially in social media arguments. In addition, we draw some findings from our empirical results, which will help people better engage in future persuasive conversations

Proceedings of the International Workshop on EuroPLOT Persuasive Technology for Learning, Education and Teaching (IWEPLET 2013)

"This book contains the proceedings of the International Workshop on EuroPLOT Persuasive Technology for Learning, Education and Teaching (IWEPLET) 2013 which was held on 16.-17.September 2013 in Paphos (Cyprus) in conjunction with the EC-TEL conference. The workshop and hence the proceedings are divided in two parts: on Day 1 the EuroPLOT project and its results are introduced, with papers about the specific case studies and their evaluation. On Day 2, peer-reviewed papers are presented which address specific topics and issues going beyond the EuroPLOT scope. This workshop is one of the deliverables (D 2.6) of the EuroPLOT project, which has been funded from November 2010 – October 2013 by the Education, Audiovisual and Culture Executive Agency (EACEA) of the European Commission through the Lifelong Learning Programme (LLL) by grant #511633. The purpose of this project was to develop and evaluate Persuasive Learning Objects and Technologies (PLOTS), based on ideas of BJ Fogg. The purpose of this workshop is to summarize the findings obtained during this project and disseminate them to an interested audience. Furthermore, it shall foster discussions about the future of persuasive technology and design in the context of learning, education and teaching. The international community working in this area of research is relatively small. Nevertheless, we have received a number of high-quality submissions which went through a peer-review process before being selected for presentation and publication. We hope that the information found in this book is useful to the reader and that more interest in this novel approach of persuasive design for teaching/education/learning is stimulated. We are very grateful to the organisers of EC-TEL 2013 for allowing to host IWEPLET 2013 within their organisational facilities which helped us a lot in preparing this event. I am also very grateful to everyone in the EuroPLOT team for collaborating so effectively in these three years towards creating excellent outputs, and for being such a nice group with a very positive spirit also beyond work. And finally I would like to thank the EACEA for providing the financial resources for the EuroPLOT project and for being very helpful when needed. This funding made it possible to organise the IWEPLET workshop without charging a fee from the participants.

Emergent Influence Networks in Good-Faith Online Discussions

Town hall-type debates are increasingly moving online, irrevocably transforming public discourse. Yet, we know relatively little about crucial social dynamics that determine which arguments are more likely to be successful. This study investigates the impact of one's position in the discussion network created via responses to others' arguments on one's persuasiveness in unfacilitated online debates. We propose a novel framework for measuring the impact of network position on persuasiveness, using a combination of social network analysis and machine learning. Complementing existing studies investigating the effect of linguistic aspects on persuasiveness, we show that the user's position in a discussion network influences their persuasiveness online. Moreover, the recognition of successful persuasion further increases this dominant network position. Our findings offer important insights into the complex social dynamics of online discourse and provide practical insights for organizations and individuals seeking to understand the interplay between influential positions in a discussion network and persuasive strategies in digital spaces

Power of Speech Styles: A Relational Framing Perspective

This study advances understanding of powerful and powerless language effects by incorporating a relational framing perspective. Relational framing theory (RFT) suggests that when messages are interpreted using a dominance frame, issues regarding persuasion, influence, and control become salient. When exchanges are framed by affiliation, however, issues of liking, attraction, and regard become salient. Power of speech style researchers have instantiated dominance-framed interactions in their experiments primarily, thus leaving affiliation-framed interactions largely ignored. Addressing this gap, this study considered the effects of relational framing differences on participants’ evaluation of speech style variations. Consistent with previous literature and in partial support for the RFT derived hypotheses, this study found that when the exchange was framed by domination, powerless language negatively affected speakers’ superiority, general control, dynamism, and control over outcome. However, effects were much less apparent when exchanges were framed more by affiliation than domination. These findings warrant further investigation concerning when exactly powerless and powerful language effects exist in day-to-day interactions

The Influencer Effect: Exploring the Persuasive Communication Tactics of Social Media Influencers in the Health and Wellness Industry

With the emergence of social media platforms such as Instagram and TikTok, social media influencers (SMIs) have been a growing source of information in the health and wellness industry. Through their creative, informative, and appealing content, SMIs have the innate ability to reach and attain a large following on social media platforms. The purpose of this study is to ascertain an understanding of the persuasive tactics employed by SMIs in the creation and dissemination of information in the health and wellness industry. Using the theoretical framework of Aristotle’s Rhetorical Appeals and Fisher’s Narrative Paradigm, this qualitative study seeks to examine the key persuasive tactics used by SMIs in the health and wellness industry. Using content analysis, the social media content of SMIs was collected and analyzed to find emerging themes related to the rhetorical appeals and narration. In addition, a comparative analysis of the persuasive tactics used by SMIs and subject-matter experts (SMEs) was conducted. Findings showed that SMIs rely heavily on the appeals that allowed them to present themselves as credible, relatable, and similar to their followers; SMEs rely strongly on the logos appeal using technical language, memes, and textual graphics to educate the audience. Through this study, using the findings of the content and comparative analysis, a list of best practices of key persuasive tactics has been established to enable SMEs to be more effective in encouraging online users to adopt health information

Discourse Analysis: varieties and methods

This paper presents and analyses six key approaches to discourse analysis, including political discourse theory, rhetorical political analysis, the discourse historical approach in critical discourse analysis, interpretive policy analysis, discursive psychology and Q methodology. It highlights differences and similarities between the approaches along three distinctive dimensions, namely, ontology, focus and purpose. Our analysis reveals the difficulty of arriving at a fundamental matrix of dimensions which would satisfactorily allow one to organize all approaches in a coherent theoretical framework. However, it does not preclude various theoretical articulations between the different approaches, provided one takes a problem-driven approach to social science as one?s starting-point

What Makes a Review Credible? Heuristic and Systematic Factors for the Credibility of Online Reviews

In the digital transformation era, online reviews have become an important source of information for decisions about purchases. Research shows that online reviews influence users’ behaviors and product sales. However, questions remain about how and why users assess the credibility of online reviews for different products/services on different websites. Using semi-structured interviews as a way of understanding how users assess the credibility of online reviews, we propose a comprehensive credibility analysis model for online reviews. The proposed model extends a model we previously proposed; and uses the Heuristic Systematic Model (HSM) as a theoretical lens, which helps us to understand different features that impact the credibility of online reviews. Our findings reveal several factors which impact the credibility of online reviews that have not been identified in the previous literature
