In this paper, we show how the use of ontologies has helped us address some key issues facing ubiquitous computing environments; improving interoperability between entities, discovery and matchmaking, and context awareness. Ontologies establish a joint terminology between members of a community of interest and provide a basis for achieving semantic interoperability. We have integrated the use of ontologies in our Smart Spaces framework GAIA [10, 13]. We show that ontologies provide important capabilities for Ubiquitous Computing infrastructure, and context-aware computing.
