OWL-based location ontology for context-aware services

Abstract

Diverse location-sensing technologies must be integrated to meet the requirements of generalized location-awareness in ubiquitous computing environments. A formal and comprehensive ontology - based modelling of location makes it possible to derive and inte- grate consistent high-level location information from sparse, het- erogeneous location data. Defined this way, location information may provide a contextual common denominator for the semantic modelling of services in a service-oriented architecture.
