Defining an ontology for fall prevention system design

The fall is one of the leading causes of death for elderly. Falls in elderly are caused by multiple factors, such as the aging process itself, persons' behavior, habits and environment. Expert knowledge about all these risk factors is required to provide the right recommendation in order to prevent falls. We have worked on the design of a knowledge-based system. An ontology was defined capturing the core knowledge to be used in the system in order to allow falling risk evaluation and definition of the adapted recommendations.
