Proposed Evaluation Framework for Adaptive Hypermedia Systems

Although a number of frameworks exist for the evaluation of Adaptive Hypermedia Systems (AHS), recently suggested layered frameworks have proved useful in identifying the exact cause of the adaptation failure or any other error in the system. This paper presents an evaluation framework for AHS for internet which is an extension of the layered frameworks and adds new dimensions to them. It treats evaluation as an integral part of development process of AHS and also evaluates the successful access of AHS on the internet. The framework has four dimensions which are orthogonal to each other – Environment – the environment in which AHS is accessed, Adaptation – the type of adaptation used, Development Process – software engineering life cycle steps used for developing AHS and the Evaluation Modules – the layers of AHS which are evaluated in context of other dimensions.
