In this paper, to tackle with uncertainty in the real world, the light-weight ontology drive approach is proposed for the realization of context dependent services. We concentrate on position information and an operation history, as a user's context, and develop our location-aware content delivery system. The evaluation experiment of our location estimate engine is performed in Akihabara software showcase at Information Technology Research Institute. Furthermore, through the proofing experiment in Expo 2005 Aichi, our proposed architecture is confirmed to enables us to realize the real world application of context dependency. Finally, we compare our location-aware content delivery system and related researches, and discuss the advantage of our system.
