An empirical evaluation of an adaptive web site

ABSTRACT

This paper describes the evaluation of an adaptive commercial web site offering a set of utilities tailored on the basis of user needs. We compared the site with the non-adaptive variant in order to study how the adaptivity increases the success in retrieving information and reduces the amount of actions needed to solve the tasks. Moreover, we considered the preference towards the two alternative versions and the user satisfaction.
