A FRAMEWORK FOR CONTEXT MODELING IN ADAPTIVE WEB APPLICATIONS

Modern Web systems that provide content to heterogeneous user groups using different devices have to deal with varying context information to support context-awareness. Accomplishing this requirement necessitates sensing, processing, and representing that information. Still, up to now there is a lack of reusable solutions for efficient context management. Therefore, this paper presents a component-based extensible framework for modeling context information that can be effectively used for adapting Web applications. The framework allows for faster development and deployment of context-aware adaptive Web applications and provides a set of modeling components supporting important application domains such as location-based services, device independence, and personalization. To support the addition of further context modeling techniques, it provides generic extension interfaces. Besides, this paper shows how the framework can be utilized by existing Web systems and presents a novel adaptation mechanism for Rich Media Web applications providing seamless integration of various complex multimedia formats.
