标题： From Public Square to Echo Chamber: The Fragmentation of Online Discourse

摘要： 本文探讨了社交媒体算法和信息茧房如何导致在线话语的碎片化，加剧意识形态分歧并破坏共同理解。 借鉴迈克尔·桑德尔对社区和共同价值观的哲学强调，该研究探讨了在社会紧张时期，数字平台如何放大包括性别歧视、种族主义、排外主义、能力歧视、恐同和宗教不宽容在内的歧视性话语。 通过分析数字社区的动态，这项研究突出了在应对现实世界事件时，话语碎片出现和演变的机制。 研究结果揭示了社交媒体结构如何加剧两极分化，限制跨群体对话，并侵蚀公正社会所必需的集体推理。 本研究将哲学观点置于社交媒体互动的计算分析之中，为数字时代碎片化话语所带来的挑战提供了细致的理解。 显示英文摘要

摘要： This paper examines how social media algorithms and filter bubbles contribute to the fragmentation of online discourse, fostering ideological divides and undermining shared understanding. Drawing on Michael Sandels philosophical emphasis on community and shared values, the study explores how digital platforms amplify discrimination discourse including sexism, racism, xenophobia, ableism, homophobia, and religious intolerance during periods of heightened societal tension. By analyzing the dynamics of digital communities, the research highlights mechanisms driving the emergence and evolution of discourse fragments in response to real world events. The findings reveal how social media structures exacerbate polarization, restrict cross group dialogue, and erode the collective reasoning essential for a just society. This study situates philosophical perspectives within a computational analysis of social media interactions, offering a nuanced understanding of the challenges posed by fragmented discourse in the digital age.
