No one can deny the importance of fans in spectator sports. Sports fans' tweets are an excellent big data source for investigating large-scale spatial-temporal dynamics of fan behavior. Using tweets related to the 2019 National Basketball Association (NBA) Finals between the Toronto Raptors and the Golden State Warriors, we conducted exploratory analyses of fan behavior dynamics and validated the fan behavior theories. Several behavior patterns were identified. Peak tweeting frequencies happened near the end of each game, after key incidents, and during the daytime the following day. National identity could elevate Canadian viewers' enthusiasm for the games. States/provinces that are geographically close to the teams or have connections to key players had higher tweeting densities. Significant local hot spots of positive tweet percentages towards the Warriors were found near California, which clearly demonstrates the Warriors' fan base. Generally, a team's relative positive percentage of tweets increased after a win, decreased after a loss, and moderated by key incidents. The trends of fans' attitudes associated with the game results in Ontario were consistent with the theoretical fan behavior tendencies, including Basking in Reflected Glory (BIRGing) and blasting. The identified patterns and validated theories are transferable to other spectator sports.

没有人可以否认球迷在观众运动中的重要性。体育迷的推文是研究球迷行为的大规模时空动态的绝佳大数据来源。使用与多伦多猛龙队和金州勇士队之间的2019年美国国家篮球协会（NBA）总决赛相关的推文，我们对球迷行为动力学进行了探索性分析，并验证了球迷行为理论。确定了几种行为模式。每次比赛快要结束时，发生关键事件后以及第二天的白天，发推文的峰值频率都很高。国家身份可以提高加拿大观众对奥运会的热情。在地理位置上靠近团队或与主要参与者有联系的州/省的推文密度较高。在加利福尼亚附近发现了对勇士的推文百分比为正的重要局部热点，这清楚地表明了勇士的粉丝群。通常，团队的相关推文的相对正向百分比在获胜后增加，在输球后减少，并通过关键事件来缓解。与安大略省比赛结果相关的球迷态度趋势与理论上的球迷行为倾向一致，包括《反光的晒太阳》（BIRGing）和《爆炸》。确定的模式和经过验证的理论可以转移到其他观众运动中。与安大略省比赛结果相关的球迷态度趋势与理论上的球迷行为倾向一致，包括《反光的晒太阳》（BIRGing）和《爆炸》。确定的模式和经过验证的理论可以转移到其他观众运动中。与安大略省比赛结果相关的球迷态度趋势与理论上的球迷行为倾向一致，包括《反光的晒太阳》（BIRGing）和《爆炸》。确定的模式和经过验证的理论可以转移到其他观众运动中。
