Power, R., Lewis, D., O'Sullivan, D., Conlan, O., Wade, V. ‘A context information service using ontology-based queries’ in proceedings of the Workshop on Advanced Context Modelling, Reasoning and Management, Nottingham, UK, September 2004
Ubiquitous computing environments have the potential to
provide rich sources of information about a user and their
surroundings. However, the nature of context information
means that it must be gathered in an ad-hoc and
distributed manner with many devices and sensors storing
potentially relevant data. In an ad-hoc ubiquitous
computing environment, retrieval of context information
cannot rely on a fixed meta-data schema. This works
shows how an ontology driven context service architecture
may perform distributed open schema queries over
heterogeneous context sources in a potentially
