The research on semantic search of urban features based on Oracle semantic technology

In this paper, the semantic information of geographic features is researched. And, the semantic information of geographic features is used to help the search of geographic features. Semantic information of geographic features includes: spatial semantic information, geographic features category semantic information and the semantic information the users add. Chinese administrative ontology and the basic geographic features category ontology are constructed on the basis of some relevant standards, and the two ontology are loaded into Oracle semantic to help the search of geographic features. This paper also complete a prototype system shows the feasibility of the semantic search of geographic features.
