Abstract The iGenda framework is a cognitive assistant that helps care-receivers and caregivers in the management of their agendas. One of the problems detected in systems of this kind is the lack of user engagement. This engagement can be improved through the application of persuasion techniques in order to convince users to act in a specific way. According to this, this paper presents a new architecture that will allow the system to select and recommend activities that potentially best suits to the users’ interests based on argumentation techniques.

Abstract This paper proposes a model for group formation in elderly communities using Coalition Structure Generation Problem implemented by Genetic Algorithms. The model parameters are physical requirements, preferences and social relationships, being the model able to learn from each execution and improve the future configurations. The results show near-optimal solutions to all proposed scenarios, beating greatly the computational time of CPLEX.
