该地图由计算机科学家Alan Mislove和Sune Lehmann、网络科学家Yong-Yeol Ahn和Jukka-Pekka Onnela、精神病学及经济学家James Niels Rosenquist共同构思和创建,它提供了一个有说服力的案例来说明Twitter是一个反映大众思想状态情况的信息资源库。每秒种都有数以万计的推特状态被发布。对于个人而言,对其每条推特状态感兴趣的主要群体是其推特用户中的朋友和粉丝。但是如果将所有推特状态整合到一起,它们将提供更多的信息。类似于人类的每个神经元组合到一起形成人的意识,这些数以十亿计的推特状态可能构成有意义的包含整个系统信息的宏观状态,而不单单只是一个推特用户的个人信息。该地图研究了在2006年9月到2009年8月期间3亿美国用户发布的公共推特信息的情感。图中推特的绝对数量用等密度示意图来表示——各州面积的大小反映了其推特数量的多少。每条推特的情感是基于英语词汇情感规范(Affective Norms for English Words,ANEW)的词表来推断的,这个情感词表可以对每个单独的英语单词表达的情感进行打分。每个州的颜色依据过去三年中每个小时的平均情感状态来绘制的。想要直观见证美国国家总体情感状况的起伏变化,请访问 http://www.ccs.neu.edu/home/amislove/twittermood 观看“国家的脉搏”(Pulse of the Nation)的延时视频。
