Definition:Fuzzy techniques for context modeling allow the representation of uncertainty.
Context Representation Formalisms
Context-awareness in the field of multimedia applications means that the user’s situation wherein he or she consumes multimedia documents is known to the system. Adaptation to context means to exploit the potentials, meet the restrictions, and fulfill the requirements so that the user stands to benefit from the multimedia presentation to the best. However, the exhaustive, accurate description of a user’s actual situation is extremely complex due to two reasons: (1) No context model is able to fully cover all aspects of the “real world” because of complexity restrictions, and (2) not every aspect of the user’s context can be defined and measured exactly. Thus, context attributes may remain unknown, unsure, or are afflicted with uncertainty, or fuzziness. To solve issue (1), the user context description model must be reduced to a trade-off between expressiveness...
