乔治·弗洛伊德被杀后推文的道德价值映射
Mapping Moral Valence of Tweets Following the Killing of George Floyd
摘要：
记录明尼阿波利斯警官德里克·肖文杀害乔治·弗洛伊德的病毒视频激发了全国范围的抗议活动，使全国关注美国普遍存在的种族不公正和对黑人社区有偏见的警务做法。Black Lives Matter运动使用社交媒体是活动家促进该事业并在全国组织1，400多场抗议活动的主要途径。最近的研究表明，社交媒体上的道德讨论是社会变革的催化剂。这项研究试图通过分析位于洛杉矶的40，000多条推文来揭示塑造Black Lives Matter Twitter讨论的道德动态。本研究的目标是（1）开发用于绘制Twitter上道德话语结构的计算技术;（2）了解社交媒体激进主义与抗议之间的联系。
英文摘要：
The viral video documenting the killing of George Floyd by Minneapolis police officer Derek Chauvin inspired nation-wide protests that brought national attention to widespread racial injustice and biased policing practices towards black communities in the United States. The use of social media by the Black Lives Matter movement was a primary route for activists to promote the cause and organize over 1,400 protests across the country. Recent research argues that moral discussions on social media are a catalyst for social change. This study sought to shed light on the moral dynamics shaping Black Lives Matter Twitter discussions by analyzing over 40,000 Tweets geo-located to Los Angeles. The goal of this study is to (1) develop computational techniques for mapping the structure of moral discourse on Twitter and (2) understand the connections between social media activism and protest.
