摘要
面向时空实体管理和时空知识计算的现实需求,基于地球剖分网格框架GeoSOT,提出了网格时空知识图谱构建方案,将离散的时空网格作为知识图谱的节点,实现对时空实体和时空特征的标准化建模。同时提出了网格时空知识图谱的时空知识判定方法,并针对“海洋行船”场景构建了知识图谱实例,进行了时空知识判定应用实验。实验结果验证了基于网格时空知识图谱的时空知识判定方法的有效性与泛用性。
Adderssing at the practical needs of spatio-temporal entity management and knowledge computation,this paper proposes a grid spatio-temporal knowledge graph construction scheme based on GeoSOT.The discrete spatio-temporal grids are used as the nodes of knowledge graph to achieve standardized modeling of spatio-temporal entities and features.The knowledge judgment method for grid spatio-temporal knowledge graph was also proposed,a knowledge graph instance was constructed based on the"sailing on the ocean"scene.The experimental results validate the effectiveness and universality of the spatio-temporal knowledge judgment method based on grid spatio-temporal knowledge graph.
