Résumé en anglais

Continuous location-dependent queries can be considered as key elements for the development of different categories of location-based and context-aware services. Most work on location-dependent query processing focuses, however, on outdoor environments. The aim of this research is to study location- and context-aware services and queries in indoor environments (e.g., houses, commercial malls, etc.), with a special focus on navigation-related queries (i.e., mainly path search, range, and nearest neighbour queries). This paper presents a hierarchical and context-dependent spatial data model, which leads to the consideration of other context dimensions besides the location of the involved entities, such as time and user profiles. Moreover, the semantics of a continuous-based query language for location-dependent queries is presented. Some motivating examples of location-dependent queries are illustrated, which show the power of the query grammar proposed.< Réduire
