On uncertainty in context-aware computing: appealing to high-level and same-level context for low-level context verification
2004 (English)In: Proceedings of the 1st International Workshop on Ubiquitous Computing, IWUC 2004 / [ed] S.K Mostefaoui; Z. Maamar; O. Rana, INSTICC Press, 2004, 62-72 p.Conference paper (Refereed)
There is an inherent chasm between the real-world and the world that can be perceived by computer systems, yielding uncertainty and ambiguity in system perceived context, with consequent effect on the performance of context-aware systems. While the problem is complex in depth and breadth, we explore an approach where context is characterized at different levels of abstraction, and where contextual information at high-levels of abstraction and sensed context at low-levels of abstraction can be used to validate and correct low-level sensed context such as location. We describe a randomly generated simulation of locations that might be sensed by a positioning technology, and how our approach can be used to validate and correct the sensed locations.
