“…While the field of context-aware computing is relatively young, a number of powerful context-aware systems such as Context Toolkit [9] and Hewlett Packard's Cooltown [10] have been developed, but most of them shared a weakness in supporting knowledge sharing and context reasoning because of their lack of ontology [11]. This weakness has been addressed by projects like GAIA [12], PSI [13] and VTT research [14].…”

Abstract. The availability of portable computing devices and advances in wireless networking technologies have contributed to the growing acceptance of mobile computing applications and opened the door for the possibility of seamless and pervasive services in mobile environments. However, with the dilemmas of limited device capabilities, network connectivity, transmission range and frequent changes, due to users and/or devices mobility, Internet-oriented wireless applications face challenges in terms of computation and interaction. These challenges elaborate with the inevitable demand for such applications to adapt to users' situations, their profiles, and the resources provided by the operating environment. Taking into account contextual information is an essential ingredient to cope with the frequent changes in mobile environments and hence provide adequate solutions for achieving adaptability, reliability, and seamless service provisioning. This paper introduces the use of policies over semantically modeled context as a technique for generating implicit context information and making use of context in mobile computing in general and internet-computing in specific. A context-sensitive instant messaging application demonstrates our proposed model using agent technology.

The notion of context appears in computer science, as well as in several other disciplines, in various forms. In this paper, we present a general framework for representing the notion of context in information modeling. First, we define a context as a set of objects, within which each object has a set of names and possibly a reference: the reference of the object is another context which "hides" detailed information about the object. Then, we introduce the possibility of structuring the contents of a context through the traditional abstraction mechanisms, i.e. classification, generalization, and attribution. We show that, depending on the application, our notion of context can be used as an independent abstraction mechanism, either in an alternative or a complementary capacity with respect to the traditional abstraction mechanisms. We also study the interactions between contextualization and the traditional abstraction mechanisms, as well as the constraints that govern such interactions. Finally, we present a theory for contextualized information bases. The theory includes a set of validity constraints, a model theory, as well as a set of sound and complete inference rules. We show that our core theory can be easily extended to support embedding of particular information models in our contextualization framework.
