An Ontology-Based LBS System

Location based services can exploit geographical information to provide users with proper services and information. However, the existing LBS systems can only deal with longitude, latitude and altitude, but can not interpret the semantic of locations. In this paper we propose an ontology-based LBS system, which introduce OWL encoded ontology and the corresponding reasoning approaches. With the support of rule-based and ontology-based reasoning, consistency can be checked; implicit information can be obtained; and the semantic similarity can be measured. The performance evaluation results indicate that the presented methods are efficient. Finally, a prototype is also given in the paper.
