基于Jena和地理本体的空间查询与推理研究

The application of jena in spatial information query and reasoning based on geo-ontology

Jena根据OWL本体定义将地理数据进行RDF资源标注,形成带有语义信息的数据,便于地理空间数据的语义查询和推理。深入讨论Jena在基于地理本体的空间信息查询和推理中的应用机制,将用户针对数据源的查询转换为对地理本体的查询;利用建立在逻辑基础上和空间关系基础上的地理本体,发现空间数据源中一些隐含的概念或关系。结合实例,实现基于本体的地理空间信息查询和在自定义规则下利用Jena推理机的空间推理。

Jena could realize RDF resource tag by definition of geo-ontology descripted by OWL,form data with semantic information and make semantic query and reasoing application of geo-spatial data easily.The paper discussed Jena and its application mechanism in query based on ontology,transfered the spatial data query focus on data source to query based geo-ontology;discovered hiden concepts and relations in spatial data source using geo-ontology built on logic and spatial relation,given a query and reasoning example based on geo-ontology and Jena resoning machine using self definition rules.
