Location-aware systems provide customised services or applications according to users'
locations. While much research has been carried out in developing models to represent …

Location-based services (LBSs) play more and more important roles in our daily life with the
prevalence of mobile devices and the internet. Location modeling is a significant research …

Location is one of the most important elements of context in ubiquitous computing. In this
paper we describe a location model, a spatial-aware communication model and an …

Location-based applications require a well-formed representation of spatial knowledge.
Current location models can be classified into symbolic or geometric models. The former …

We use semantic web technology to utilize the world wide web for a large-scale ubiquitous
(qualitative and geometric) location model, in order to achieve shareability and extensibility …

Location is a core concept in most pervasive systems-and one that's surprisingly hard to
deal with flexibly. Using a location model supporting a range of expressive representations …

Location models are crucial for providing location-dependent data to context-aware
applications. In this paper, we present two approaches for modeling location information …

Location models of the physical world play several roles in ubiquitous computing systems,
including the provision of physically-scoped lookup, an abstraction layer between sensors …

Location models play an important role in location-based services (LBSs), because LBSs
require a well-defined representation of location knowledge to support location browsing …

Location modeling and representation are crucial technologies for context-aware
applications. In this paper, we present a novel location model combining the virtues of both …
