【 摘 要 】

The objective of the work is to propose a context driven dynamic adaptation model for knowledgeassessment in E-Learning system through software as component. Most of the existing models deployed forKnowledge Management have focused on the contents of the assessment while giving less emphasis to thecontext with which the assessment services are to be rendered. A timed automaton has been proposed to acceptthe user requests for services navigating through the different rules resulting in a change in the behavioralstates. The various states are then rewritten according to the runtime policy of application incorporating theuncertainties pertaining to the nature of services, content, time and policy changes. This context drivenapproach considers the nature of the application and its content along with the run time policy of differentapplications. An architectural framework with dynamic adaptation model has been implemented using PHP andMySQL Server and extensive testing has been carried out. Interesting inferences have been observed in terms ofthe session time and rewriting rules.
