The USHER System to Generate Semantic Personalised Maps for Travellers
Abstract
Map applications based upon Geospatial Information Systems (GIS) are seen as a key application area for mobile users, e.g., to enable travellers and mobile assets to be located and tracked, with respect to spatial views, or maps, of destinations and routes. However, current GIS map services tend to lack support for personalisation to: enable users to set preferences based on their context and user profiles; to customise searching and selecting content; to markup maps in-situ forming a personalised spatial memory. For example, current services can’t store, spatial short-cuts, good parking spaces, etc, which have been discovered in-situ, in the physical world. These GIS map services also tend to lack a provision to enable such tagged personal spaces to be used within shared social spaces, i.e., to share spatial memories. An ongoing spatial-aware framework called USHER (Ucommerce Services HEre for Roamers), has been extended, to semantically adapt and personalise maps, and tested. The contributions of this framework are: an ontology-based representation of dynamic user preferences interlinked to a domain model that is able to detect shifts in user interests; the creation of sharable user markup data governed by an access control matrix; the generation of personalised annotated GIS maps.
