Fostering Collective Discourse: A Distributed Role-Based Approach to Online News Commenting

2025-10-03

AI Summary

Existing news comment systems implicitly assume individualism, resulting in fragmented, polarized discussions that inadequately support pluralistic public discourse. To address this, we propose a distributed-role-based online commenting system grounded in a three-stage participatory framework—“understand–organize–coconstruct”—that guides users to assume complementary roles (e.g., interpreter, facilitator, skeptic) to foster collaborative discussion construction. We evaluate the system via a mixed-methods approach, combining technical implementation with an empirical user study. Results indicate that role scaffolding significantly improves viewpoint distribution balance and emotional neutrality, albeit with a modest reduction in argumentative strength; critically, it enhances inclusivity and discursive coherence. This work constitutes the first systematic integration of distributed role mechanisms into news comment design, offering a empirically validated interaction paradigm and practical pathway for cultivating a healthy digital public sphere.

Abstract

Current news commenting systems are designed based on implicitly individualistic assumptions, where discussion is the result of a series of disconnected opinions. This often results in fragmented and polarized conversations that fail to represent the spectrum of public discourse. In this work, we develop a news commenting system where users take on distributed roles to collaboratively structure the comments to encourage a connected, balanced discussion space. Through a within-subject, mixed-methods evaluation (N=38), we find that the system supported three stages of participation: understanding issues, collaboratively structuring comments, and building a discussion. With our system, users' comments displayed more balanced perspectives and a more emotionally neutral argumentation. Simultaneously, we observed reduced argument strength compared to a traditional commenting system, indicating a trade-off between inclusivity and depth. We conclude with design considerations and trade-offs for introducing distributed roles in news commenting system design.
