Our research group has been studying person-centered care (PCC) support systems for elderly people living at home, using contextual information of individual users (called user context). PCC is an ideal care principle, which monitors and understands individual circumstances, and plans and executes optimized care. Since the current systems individually manage different user contexts, reusing the contexts across multiple systems is quite different. In this paper, we propose a new service that uniformly manages the user context, and allows external applications to retrieve necessary user contexts efficiently. More specifically, the proposed service gathers heterogeneous data from different systems, and standardizes the data with a common database with domain-independent attributes of when, who, whom, where, what, how, and why. Using a practical use case, we show how the proposed service efficiently manages user contexts.
