Space-time geographic space visualization analysis method

The invention discloses a space-time geographic space visualization analysis method. The method comprises the following steps of preprocessing untagged source data to obtain a time entity, a place entity and event words; constructing a data cube by time, geographic longitude and geographic latitude as three dimensions; clustering the event words under selected space-time granularity into at least one event; and constructing a space-time geographic information visualization system. 种时空地理空间可视化的分析方法，包括以下步骤：对未标注的源数据进行预处理，获得时间实体、地点实体及事件词；将时间、地理经度、地理纬度作为三个维度构建数据立方体；将选定时空粒度下的事件词聚类为至少个事件；以及构建时空地理信息可视化系统。
