In this study, we reviewed the literature on community conflict and conflict mediation and performed empirical study with LDA-based topic modeling to understand conflict patterns in Suseong-gu, Daegu, and then analyzed cases of conflict mediation through the civil jury system. It was conducted based on analysis of civil complaint jury minutes for about 10 years (April 28, 2011 - July 3, 2019) and news data from the same period. From this, the implications of the civil jury system as a community conflict management mechanism were presented through an understanding of complex and multidimensional conflicts in the community. The main concepts of the Citizens' Jury System identified in the study consist of three components. Firstly, there are conflicting parties seeking understanding, followed by the forum of communication, which could be referred to as the “public sphere,” created through complaints arbitration meetings to facilitate dialogue. Lastly, there is the neutral third-party group who mediate to induce agreement among conflicting parties and thereby reduce or resolve conflicts. The process of the Citizens' Jury meetings not only prevents the polarization of conflicting groups but also holds significant implications beyond the institutional aspect of conflict resolution, including rational mediation by a third party well-versed in local community affairs, overcoming/solving rational ignorance through information sharing in the conflict public sphere, voluntary participation by complaints arbitrators, and compliance with arbitration decisions, contributing to the augmentation of social capital and effective conflict resolution.
