Sentiment analysis (polarity supervised classification) of Twitter data posted in English about the 10th anniversary of the 2010 Maule earthquake in Chile

This database contains the supervised classification of the tweets originally posted in English related to the 10th anniversary of the Maule Earthquake in Chile on Febrary 27, 2010. Tweets were collected by a third-party vendor between December 11, 2019 to April 23, 2020 including the hashtags: #27F, #Maule, #PorUnaLeyDeCostasEnChile, #Chile and #Terremoto. A total of 44,189 tweets were collected, from this sample, only 237 (0.54%) tweets were originally posted or retweeted in English, which can be explained by the fact that Chile is a Spanish speaking country. After removing the not related tweets the sample was reduced to 121 (0.27%). Despite being a small sample, based on additional analysis, we state that this is a representative sample of the opinions related to this commemoration. The high number of not related tweets is given that the hashtag #27F is also included in tweets related to celebrating the Independence of the Dominican Republic and the International Polar Bear Day; the birthday of José Vasconcelos (Mexican writer, philosopher, and politician), Elizabeth Taylor (American actress) and José Antonio Meade Kuribreña (Mexican politician). Other tweets that include the hashtag #27F are those commemorating the 'Caracazo' (protests, riots and looting that started on February 27 1989 in Caracas, Venezuela); the dead of Mauricio Garcés (Mexican actor) and Eyker Daniel Rojas (Venezuelan citizen assassinated during the Caracazo).

本数据库收录了与智利马乌莱地震十周年相关的英文推文的监督分类。这些推文由第三方供应商于2019年12月11日至2020年4月23日收集，包括以下标签：#27F、#Maule、#PorUnaLeyDeCostasEnChile、#Chile 以及 #Terremoto。总计收集了44,189条推文，其中仅237条（占比0.54%）为原文发布或转发自英语用户，这一比例可由智利为西班牙语国家的事实得以解释。在剔除无关推文后，样本量减少至121条（占比0.27%）。尽管样本量较小，但经过进一步分析，我们认为这是关于此次纪念活动意见的代表性样本。无关推文数量众多，部分原因在于标签#27F亦被用于纪念多米尼加共和国的独立日、国际北极熊日、墨西哥作家、哲学家、政治家何塞·瓦斯科内索斯（José Vasconcelos）和美国女演员伊丽莎白·泰勒（Elizabeth Taylor）的诞辰，以及墨西哥政治家何塞·安东尼奥·梅德·库瑞比尼亚（José Antonio Meade Kuribreña）的生日。其他包含#27F标签的推文还包括纪念委内瑞拉加拉加斯发生的‘卡拉克索’（抗议、暴乱和抢劫，始于1989年2月27日）、墨西哥演员毛里西奥·加西亚斯（Mauricio Garcés）和在‘卡拉克索’期间被暗杀的委内瑞拉公民埃伊克·丹尼尔·罗哈斯（Eyker Daniel Rojas）的逝世。
