Ontology Alignment: First Step towards Voice Control for Smart-Home Assistive Scenarios

With the ageing of the world population, Do-ItYourself approaches and Smart Personal Assistant are combined to provide customised systems that help people in their daily lives, including fostering their self-reliance and promoting ageing in place, even when these people have cognitive disabilities or perceptual impairments such as “Alzheimer” disease. Ambient Assisted Living systems which rely on this combination can also help caregivers reduce their workload by giving them much relevant information about the health status and the situation of the patients at home, and, furthermore, by giving them facilities to create home automation scenarios to assist the patients. A scenario is the arrangement of daily activities in order to achieve a particular goal. In this paper, we propose a new approach to creating assistance scenarios through voice command, involving two types of ontologies, a smart home ontology (OntoDomus) and a knowledge graph of an activity/action extracted from a scenario in the form of structured knowledge. In particular, we leverage ontology alignment to process voice requests in order to create an assistance scenario for the elderly.
