Beyond position - spatial context for mobile information retrieval systems

Within context-aware mobile applications, location information usually plays a major role for information selection and adaptivity. In this paper, we explore the geospatial dimension between simple position-aware and fully context-aware information systems by examining in-depth the features of spatial context beyond mere position. We describe how these features can be used to create spatial queries in a mobile information retrieval system and further discuss the influence of spatial context to select and adapt the query results and its relation to mobile user´s information needs.
