OAFE: An Ontology for the Description of Elderly Activities

Improving the practice of activities and changing sedentary lifestyle is part of global health strategies. In this context, the establishment of an activity suggestion system adapted to the gerontological profile of the elderly arouses a major interest. In this paper, we present the approach used to model the activity and to design of Ontology of Activity For Elderly (OAFE). Among the approaches used to model knowledge, the knowledge-based approach has been used in this work as being the most effective for representing activity, managing sensor data, and reasoning about modeled knowledge. Using knowledge engineering methods, we were able to model the activity concept by considering the variables used in the definition of the elderly profile. To design OAFE, we relied on scenarios and competency questions as a means to determine ontology specifications to design and evaluate our knowledge model. The ontological approach used will allow reasoning using the OAFE ontology to establish personalized, targeted and incentive suggestions for elderly.
