Semantic location-based services

Semantic location-based services (LBS) aims to provide intelligent LBS that can find and integrate various information to better meet user requirements in location-aware context. This paper argues that traditional approaches for semantic GIServices in the Cyberinfrastructure context could be extended into the LBS. After highlighting the distinguished features of semantic LBS, i.e. context semantics and location semantics, it suggests a common semantic framework that can accommodate semantics in both LBS and GIServices. A semantic-aware LBS architecture is proposed, which supports the context-aware discovery, access, composition, and use of Web information. A case study illustrates the applicability of the approach.
