| 摘 要： | 目前,利用地理本体进行实体空间关系的表达与计算是地理信息领域的研究热点.针对这一热点,本文提出了基于地理本体空间特征的属性关系推理方法。首先,分析了空间关系计算的相关基础理论;其次,研究了基于OWL语言的地理本体空间关系表达方法;最后,以“山脉”为目标地理实体进行验证。实验表明:该方法能够有效提取地理实体的空间关系信息,计算效率较高,实用性较强。

| Abstract: | Currently using geographical ontology to express and calculate entity spatial relations is a research hotspot in the field of geographic information.Aiming at the hotspot,this paper proposes an attribute relation reasoning method based on the spatial characteristics of geographical ontology.Firstly,the basic theory of spatial relation calculation is analyzed;On this basis,the expression method of spatial relation of geographic ontology based on OWL is studied;Finally,the"mountain ranges"as the target geographic entity is verified.The experimental results show that the method can extract the spatial relation information of geographical entities effectively,and is efficient and practical. |
