Diverse kinds of services delivered to the users can be provided by enabling real-time integration of contextual dimensions. In particular, continuous location-dependent queries can be considered as key elements for the development of different categories of context-aware services. However, most work on location-dependent query processing has been mainly oriented towards outdoor environments. This paper introduces a generic architecture for continuous location-dependent and navigation-related queries in indoor environments. A multi-level model of space is designed by taking into account contextual information and the hierarchical layout of an indoor environment. The semantics of a query language for continuous location-dependent queries are introduced, along with some motivating sample queries.<\/jats:p>","DOI":"10.3233\/ais-120186","type":"journal-article","created":{"date-parts":[[2019,11,29]],"date-time":"2019-11-29T18:07:12Z","timestamp":1575050832000},"page":"65-88","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Context-aware modelling of continuous location-dependent queries in indoor environments"],"prefix":"10.1177","volume":"5","author":[{"given":"Imad","family":"Afyouni","sequence":"first","affiliation":[{"name":"Naval Academy Research Institute, 29240 Brest Cedex 9, France.
