A Critical and Comparative Study of Adaptive Hypermedia Technologies

Hypermedia systems give freedom of navigation to users but majority of these systems provide same view to all of them which cause lack of interest. Adaptive hypermedia technologies resolve this problem through personalisation. Adaptive hypermedia systems adapt to the users’ preferences and previous knowledge regarding one particular domain by maintaining user model. In this way, adaptation improves human computer interaction and leads users towards more relevant information. In this paper, the structure of adaptive hypermedia system (AHS) comprising of domain model, user model and adaptation model is described. Then types of user model and different methods and techniques used to implement adaptation mechanism are critically and comparatively discussed. Some future prospects are also highlighted.
