Context-aware service adaptation management

Technology is paving the way for ubiquitous services. However, the delivery environment is characterized by its complexity which emanates from the diversity in end user terminals and networking infrastructures. Hence, adaptation is vital to the portability and personalization of the ever increasing content and services offered to users. Ibis paper proposes a context-aware Adaptation Manager architecture for adaptation management. The architecture aims to analyse the service delivery context to determine the required adaptations in order to enable efficient ubiquitous accessibility and personalization to the user situation and preferences. This paper presents technologies which have been identified useful for this purpose and how they are applied to deliver the functionality of the Adaptation Manager architecture, including ontology, OWL-DL, SWRL, reasoning and XSTL.
