With the widespread use of the Internet a large amount of geographical information is currently being stored and delivered over the Internet. Geographic references of Web page are information entities that are discovered from the context and can be mapped to some geographic locations. They are very useful for explaining real world information and for knowledge discovery. In the paper, a Geo-ontology is designed and developed to describe geographic references on the Semantic Web. Based on it, a tool is developed to georeferencing and the result is saved in OWL .The research is an attempt to step to Semantic Web and provide us with direction for future work.
