Personalized location-based services [PDF]

Proceedings of the 2011 iConference, 2011
Location-Based Services (LBS) are based on a combination of the inherent location information about specific data, and/or the location information supplied by LBS clients, requesting location-specific and otherwise customized services. The integration of location-annotated data with existing personal and public information and services creates ...
