摘要
引入本体论思想研究空间关系描述与推理,目的是为了实现地理空间信息的共享和互操作。从地理本体的概念出发,建立了符合常识空间认知的空间关系描述模型。以河南省行政区划、交通、旅游景点为基础数据,构建了空间关系本体实例库;自定义了空间关系推理规则,并实现了规则的SWRL表达;设计了基于本体的定性空间关系推理总体框架,并结合应用实例进行了推理实验,有效地验证了空间关系本体推理机制的可行性。
This paper imported the ontology theory to study spatial relation for realizing the geographic information sharing and interoperability.It constructed the spatial relation description model according with the concept of geo-ontology.It established a spatial relation ontology instance base based on region,traffic and scenery data of Henan province.Self-defined and expressed spatial relation reasoning rules.Designed a qualitative spatial relation reasoning frame based on ontology and an did experiment for reasoning correspondingly combing with application instances.It validated effectively the feasibility of spatial relation reasoning mechanism.
