Abstract. Advanced Location Based Service (LBS) applications have to integrate information stored in GIS, information about users’ preferences (profile) as well as contextual information and information about application itself. Ontology engineering provides methods to semantically integrate several data sources. We propose an ontology-driven LBS development framework: the paper describes the architecture of ontologies and their usage for retrieval of spatially related objects relevant to the user. Our main contribution is to enable personalised ontology driven LBS by providing a novel approach for defining personalised semantic spatial relationships by means of ontologies. The approach is illustrated by an industrial case study.

Keywords: Ontology-based information retrieval, domain ontology modelling, mobile IS, personalised LBS, semantic LBS
