LOCATION-BASED SERVICE MIDDLEWARE

摘要

A middleware system is provided that is situated between the user applications and the various content databases that are to be searched in order to simplify the creation of user applications for mobile devices that use location-based services that employ ontology-based search systems. The middleware system exposes one or more services to the user application. For example, a service exposes a service that allows the user to annotate and/or tag known semantic locations. The suggested semantic POIs are selected based on a user's location and possibly context-dependent information.
