公共地图服务中访问热点区域的时空规律挖掘
|
Abstract:
公共地图服务的普及是人们步入数字生活、建设智慧城市的重要一步。如何准确地探测群体用户访问行为的时空聚集访问模式，将网络虚拟空间访问行为映射为现实世界行为，是提升公共地图服务和推动智慧城市建设的关键所在。探寻了群体用户访问公共地图服务产生的热点聚集区域的时间及空间规律，基于海量用户访问日志记录，结合分组分析、时间序列统计分析和时空三维图可视化方法，挖掘得出公共地图服务热点区域具有明显的以星期为单位的周期自相似特征，多数热点区域在周期内连续出现；基于箱形图和频率密度图的统计方法，分析得到热点区域间距在空间上呈“小间距多，大间距少”的聚集分布形态，且在不同的图层中热点区域间距分布迥异。公共地图服务用户访问时空规律揭示了用户行为意图，可将人类活动数字化，促进智慧城市建设中人地关系的发展
