Context Modeling for Context-Aware Systems

Abstract

Modeling context is a key factor for enabling context-aware systems to be responsive to users' needs and consequently for making computing "invisible".A context model, which is a product of context modeling, provides a systematic way of identifying and representing knowledge about users' environment in context-aware architecture.Through this knowledge, and its sensing and reasoning capabilities, a context-aware architecture is able to determine what is going on in the environment and share this knowledge with context-aware systems. This article presents a research work for modeling context. In particular, the article explains development of a Knowledge-intensive Context Model (KiCM). KiCM extends theory-based context models by including knowledge of users' computersand their computer-related activities. Categories of context-aware systemsSchilit et al. [3] categorize context-aware systems based on their ability to provide information or execute computing services.Similarly, Dey and Abowd [4] categorize these systems by their ability
