时空推理前沿研究综述

Overview of Advanced Spatio-Temporal Reasoning Researches

本文对时空推理及应用中若干前沿研究方向进行了综述和分析。概括了时空推理的概念和主要研究方向,总结了近10年来时空推理中时空代数、时空信息综合、时空粒度等理论方向及地理信息系统和时空数据库等应用方向的研完工作,分析了存在的问题并指出了发展趋势。

The advanced spatio-temporal reasoning researches are analysed and summarized. The major research aspects and basic conceptions are discussed. The theoretical works such as spatio-temporal algebra,integrating spatiotemporal information,spatio-temporal granularity et al. and the applied works such as Geographical Information System and spatio-temporal database are briefly introduced. The flaws of those work are pointed out. Finally the emerging trend is indicated.
