对具有不确定性的移动对象数据库的模型改进

Model Refinements in Moving Objects Databases with Uncertainty

针对带不确定性移动对象的模型在回答未来时空查询时的提问及查询计算量方面所存在的问题,提出了改进方案。该方案使移动对象数据库和用户对于信息不精确的容忍度之间得到了很好的协调。

This paper propose schemas for answering predictive spatio-temporal query when there is uncertainty associated with the model of the moving objects, and query calculation. These two refinements can get a good trade-off between Moving Objects Databases and its user about the acceptable tolerance for the imprecision of the information.
