In particular, we emphasize on the aspect of data mining in such a data model. The tasks of spatio-temporal data mining, such as a series of spatio-temporal rules and similar trajectories analysis, are discussed. We also discuss some techniques that can be adopted to improve the performance of spatio-temporal data mining. 收起
