基于本体的新疆兵团空间数据语义描述及其应用与评估

Ontology-Based Semantic Description of Spatial Data

为了解决兵团空间信息集成与数据共享的问题,本文在兵团空间信息建设现状和空间数据认知过程分析的基础上,采用空间数据本体的方法研究兵团空间数据的认知表达,并由此提出基于地理本体的兵团空间数据含义和概念框架,建立了能客观反映兵团空间实体的描述逻辑和知识表达方式。最后,在本体构建,概念类型、语义关系研究基础上对空间数据本体进行语义描述应用并予以评估。结果表明,本文利用地理本体思想对兵团空间数据进行的语义描述有效,有利于兵团空间数据共享和集成。

To solve the problem of spatial information integration and data sharing in Xinjiang Production and Construction Corps.Based on the current state of the spatial information construction of the Corps and the analysis of the cognitive process,this paper studied the cognitive expression of the Corps spatial data by using ontology,proposed the meaning and conceptual framework of the Corps spatial data based on the geographical ontology,and established a descriptive logic and knowledge representation methods which could objectively reflect the Corps spatial entity.Based on ontology construction,conceptual types and semantic relationships,this paper described and applied the spatial data of the Corps and made assessment.The results show that,the use of Geographic Ontology thinking on semantic description of spatial data is effective,and it is beneficial to the spatial information integration and data sharing in the Corps.
