摘要
为实现地理信息系统之间的语义集成,本文提出了地理本体范畴定义:即范畴中的对象描述地理本体,对象之间的态射描述地理本体之间的映射,且态射能描述地理本体间的多种语义关系;并设计了利用外推实现地理本体集成的算法,该算法既能集成同义关系,也能实现语义非对称关系的集成;最后以不同分类标准的干出滩本体为具体案例,阐述了算法的实现步骤并对实验结果进行了分析。
To realize the semantic integration between geographic information systems, this paper proposed a definition of geo-ontology category. Namely, objects in the category describe the geo-ontology, and the morphism between the objects describes the mapping and a variety of semantic relationships between geo-ontology. It then proposed a method that makes use of pushout to realize the geo-ontology merging. The method could merge not only semantically similar relations but also semantically non-symmetrical relationships. Finally, by taking differently-categorized dry shoal ontology as an example, the paper presented procedures of applying the algorithm and analyzed the experimental results.
