“Context is any information that can be used to characterize the situation of an entity. An entity is a person, place, or object that is considered relevant to the interaction between a user and an application, including the user and applications themselves.”
[Dey and Abowd’s definition]
“A system is context-aware if it uses context to provide relevant information and/or services to the user, where relevancy depends on the user’s task.”
→ context is defined as facts, expressions and rules
→ strong in the field of normalization and formality
