Abstract

This paper addresses the issue whether hypertext of paper is more appropriate for certain tasks. We chose the task of getting a quick overview of a new topic. We describe the design of a hypertext system with specific emphasis on hierarchical structuring for semi-formal knowledge representation. The domain of our application is hypertext itself. For the evaluation of our design, and more generally hypertext versus paper, we descirbe the experiment and results on the effectiveness of our system compared to a printout version. In particular, we classify the difficulty of the questions posed to the subjects in our experiment accoring to various methods. It is interesting that the achieved classifications have small correlation. There are no statistically significant differences between the performance of subjects using HIS or the paper version. We interpret this as a compensation of the adverse effects of the usually slower reading from a computer screen and unfamiliarity with the medium of hypertext.
