Context-aware systems observe the user’s current context and apply this information to the user’s benefit. When implementing context-awareness, several issues need to be considered and this paper concentrates on presenting the context information to the user. The key components needed to construct the context are identified, and a model, which allows using different visualization techniques for...
The existing personalization systems typically base their services on general user models that ignore the issue of context-awareness. This position paper focuses on developing mechanisms for cross-context reasoning of the user models, which can be applied for the context-aware per-sonalization. The reasoning augments the sparse user models by inferring the missing information from other context...
Context awareness is increasingly gaining applicability in interactive ubiquitous mobile computing systems. Each context-aware application has its own set of behaviors to react to context modifications. This paper is concerned with the context modeling and the development methodology for context-aware systems. We proposed a rule-based approach and use the adaption tree to model the adaption rul...
Humans use all kinds of information characterizing their current situation, like time, location and identity of persons nearby, to adapt their behavior to the situation and to make decisions. For example, when we speak to a person, we adapt what we say and how we say it to the social rank of the person (e.g., most people would not say “that’s nonsense” to their boss, but would to a friend). All...
Context aware systems reduce the need for user intervention and provide smarter services by considering a user’s situation. Context models decide how the contextual information is modeled and what type of context should be considered; they are essential in providing the “right” services to the users. Existing surveys of context-aware systems focus heavily on the data structures for modeling con...
Context-awareness refers to the ability to sense and adapt to context. With the rise of context-aware systems, designers are struggling with what variables should be sensed from the context. According to the definitions found in the literature, whether something belongs to context, has to do with whether it is relevant. However, what it means to be relevant is left implicit in these definitions...
The growing importance of context-awareness in the construction of adaptable systems requires the development of formal models and notations that can bring this new dimension from middleware concerns into the higher levels of modelling. In this paper, we propose a formal approach to the design of context-aware systems that is well integrated with the concepts and techniques that have been propo...
A web site presents an intrinsic graph–like spatial structure defined by pages connected by hyperlinks. This structure may represent an environment on which agents related to visitors of the web site are positioned and moved in order to track their navigation. To consider this structure and to keep track of these movements allows to monitor the site and visitors, in order to support the enhance...

Jan Recker Faculty of Science and Technology Queensland University of Technology [email protected] Michael Rosemann Faculty of Science and Technology Queensland University of Technology [email protected] Many business process modeling techniques have been proposed over the last decades, creating a demand for theory to assist in the comparison and evaluation of these techniques. A widely e...
