| 摘 要： | 提出用Voronoi空间模型来表达意像模式，Voronoi模型无岐义空间邻近关系，构建能封装对象间空间关系的拓扑网络，使用该模型将各种空间介词映射为不同的拓扑结构，GIS采用该模型，可按自然语言中空间介词描述的定性空间关系查询检索模糊地理信息。

| Abstract: | Formalization of geographical spatial image schemata is one of the keys to realize GIS interoperability and standardization, ensures that geographical information sharing reaches agreement at cognitive level and on natural language understanding,and develops intelligent GIS. It is also an important element of spatial information theory. Voronoi spatial model is proposed to represent image schemata formally. The method unambiguously defines spatial neighbor relations, establishes topological networks which can encapsulate relations between objects. The model is used for map spatial prepositions into distinct topological structure. Adopting the model, GIS can implement fuzzy geographical information query and retrieval in terms of qualitative spatial relations described by spatial prepositions in natural language. |
