An ontology based geographic knowledge representation method

In recent years, the term "ontology" has gained a good popularity within the knowledge engineering community. Ail important reason for this is present tremendous need towards knowledge sharing and knowledge exchange. Researchers widespread consider that the ontology theories research and architecture building is the important basis of realizing these targets, because any knowledge-based systems is based oil a certain conceptualization of the world and the ontology is a kind of specification of the conceptualization. In this paper, we present a method based oil the ontology to represent geographical knowledge about countries and regions. We give a particular discussion of the principle and the building steps of the geographic ontology design. For ontology-based knowledge representation, we developed an ontology description language for our methodology.
