Context Modelling Using Semantic Web Technologies

Abstract

In this paper, we propose an ontology-based context model that generically describes different contexts surrounding each user. By using ontology, it can categorize all contexts and find contextual information from relations between contexts so that it can offer adaptive services according to user's context. A user can write a context rule using a context description language that we propose and our system compiles the context rules and find relevant information. We demonstrate how our system can be used using examples from popular social network services.
