Geo-ontology researches on detailed connotation and hierarchy relationships of geographic spatial information concepts at different levels and application directions in geographic information science domain, and giving semantic identification of concepts. Relational database is often used as a basis for persistent storage of ontology to facilitate rapid operations such as search and retrieval, and...
This paper brings forth building spatio-temporal reasoning architecture and spatio-temporal query system based on adopting geo-ontology to represent spatio-temporal information knowledge and employing SWRL rules to express spatio-temporal reasoning rules. When carrying through spatiotemporal reasoning this paper adopts Jess to be a reasoner, which is the core of the whole architecture. Before carrying...
Geo-ontology provides explicit and formalized definition of shared geographic concepts, applied to aspects such as sharing and interoperating geographic information, integrating geographic information based on semantics and geographic information service. This paper adopts geo-ontology to establish logistics domain ontology so as to store abundant semantics information and represent intricate dependent...
In future, GIS will develop in the direction of popular application. Geography information sharing has become a stringent problem needed to resolve. Because people's cognition of real geographic world is different from each other, semantic discrepancy comes into being. As a result, Realization of geography information sharing has firstly to realize GIS's semantic sharing. Geo-ontology provides generally...
Spatial reasoning has gradually become a research hotspot in some domains such as GIS and spatio-temporal database. At present many spatio-temporal methods put forward by scholars are methods based on logic or algebra by and large, and researches on formalization representation and reasoning of geographic spatio-temporal knowledge are few. Geo-ontology researches detailed connotations and hierarchy...
