Ontology-based representation of activity spheres in ubiquitous computing spaces

Abstract

An Ambient Intelligence (AmI) space embeds sensing, actuating, processing and networking infrastructure in a physical (usually closed) space and offers a set of services in its digital space. In order to model the way everyday activities are carried out within an AmI space, we introduce the notion of "activity sphere". In this paper we show how the use of ontologies has helped us realize an activity sphere and we discuss how ontological components (ontologies and alignments) can be reused to support the realization of overlapping activity spheres. © Springer Science+Business Media B.V. 2010.
