The Research and Practice of Geo-ontology Construction

چکیده
From the perspective of spatial information sharing and interoperation, the concept of geo-ontology has been proposed in this paper. At first, a brief introduction to the Geo-Ontology concept has been described and the hierarchical structure of geo-ontology has also been analyzed. Then, the traditional method of ontology construction has been discussed and the existing problems have also been summarized systematically. Based on the discussions above, a mixed method of geo-ontology construction combined top-to-bottom with bottom-to-top methods has been proposed in the paper. Combined with police information sharing and interoperation application requirements, a prototype crime case geo-ontology system has been developed which can be used for the construction, management, application of geo-ontology. The research practice has proved that the mixed method of geo-ontology construction is a feasible way for practical applications.

متن کاملGeo-Ontology and Geographical Information System Extended by a first-order logic language: Application to malaria control
A geo-ontology can be built around a Geographic Information System (GIS) and enriched with a firstorder logic language under the closed-world assumption (CWA). This extended system provides knowledge representation formalisms that are aimed to describe general conceptual information. They can also be used in the construction of the knowledge base of a reasoning tool. In this paper an environmen...
