This paper investigates how spatial and temporal context informationcan be used in smart homes to detect abnormal behaviours.We discuss how various formalisms, such as probabilitytheory, the Dempster-Shafer calculus, and fuzzy logic,can be used to capture context information and argue thatfuzzy logic is the most suitable. We evaluate our approachby analysing one of the CASAS smart home datasets.
