Plan Recognition in Smart Homes - An approach based on the Lattice Theory

Plan Recognition in Smart Homes

  Assistance to people suffering from cognitive deficits in a smart home raises very complex issues. Plan recognition is one of them. After a tour of plan recognition systems and their limitations, it is proposed to use the lattice theory, combined with the action description logic, to formalize the inferential process of plan recognition into a model of reasoning by classification through a lattice structure. It is then sketched how this approach offers an effective solution to concrete recognition of ADL in a smart home. For instance, this solution enables to address the recognition of multiple interrelated plans and to classify them. This work is indeed one more brick for the deployment of a web of specialized plan recognizers in a smart home, each one using a perhaps different approach to plan recognition adapted to the context and the task to recognize.
