Performance And Satisfaction In Adaptive Websites: An Experiment On Searches Within A Task-Adapted Website

Finding information within websites is becoming an increasing challenge as the size and the complexity of websites soar. One possible solution is to adapt the view of the site to the task in hand. Although such a procedure is technically feasible, the effectiveness of such designs is yet to be tested. Assuming user scenarios that involve searches by browsing rather than structured queries, we build on models of searching in text to formulate a task representation of searches within websites. This task representation is used to model the effects of adapted websites on performance and satisfaction. We have, therefore, two main aims: (1) to propose a task representation of website searches, and (2) to use it to explore the effect of adaptive designs on performance and satisfaction.
