Abstract. The progressive increase in the percentage of old people in all European countries implies an enormous economic and social cost, which can be somehow reduced if Home Care services are improved. The K4Care European project is studying the feasibility of using Information and Communication Technologies to improve the management of Home Care. This paper details the project objectives, the K4Care Home Care model, and the declarative and procedural knowledge needed in Home Care. It also describes the architecture of the agent-based web-accessible K4Care platform, and how the intelligent agents coordinate their actions to provide the basic Home Care services defined in the model.
