Abstract

Evaluates an adaptive hypermedia system, PUSH, and compares it to a non-adaptive variant of the same system. Based on an inferred information-seeking task, PUSH chooses what to show and what to hide in a page using a stretchtext technique, thus attempting to avoid information overload. Studies how successful the subjects were in retrieving the most relevant information, and finds that the subjects' solutions were influenced by the choice made by the adaptive system. Studies how much the adaptivity reduced the amount of actions needed, and found that subjects made substantially fewer actions in the adaptive case. A 3rd measurement was the subjects' subjective preferences for the adaptive or the non-adaptive system, where it is found that the subjects clearly preferred the adaptive system
