transparent adaptive functionality for web servers
AHA! is a general-purpose adaptive hypermedia add-on for web servers. It enables a web server to serve pages with conditionally included page fragments, and with link anchors that are conditionally colored or hidden. Adaptation is based on a domain model, a user model, and an adaptation model, using concepts, pages, fragments and condition-action rules.
Where other adaptive architectures focus on specific areas of application, with a consequent layout and presentation, AHA! is centered at maintaining a user model and the generation of adaptive html regardless of actual content or layout.
