This paper describes the SimCon (Simulated Context) Generator which combines data on the state of a Virtual Reality building with the SimCon Model to generate interactive location context for the rapid evaluation of Smart Building Applications. The paper evaluates the simulated context against physical readings. The SimCon Model does not set out to replace deterministic models, but rather allow for...
Ontology-based information integration systems have been proposed to solve the problem of combining data residing at autonomous and heterogeneous sources. For such ontology based solutions to succeed in an industrial context, the ontologies and mappings need to be managed to allow them to evolve as the data sources evolve. This paper describes a dependency modeling approach to the management of mappings...
Given the diversity of information and services that an individual will want to offer and/or share in a ubiquitous computing environment, it is critical that the individual is provided with mechanisms to manage access and usage to their resources. Mirroring real life, a natural concept for people to grasp when assigning ability to access or use resources is one of "trustworthiness". In previous...
