E-learning systems are used to facilitate learning processes through Internet, computer and communication technology. E-learning is very useful especially in distance learning. However, the statistics of unusable systems are high which means users are unable to operate the system. Fancy Web sites which are loaded with too many features and graphics make them even harder to use. Factors such as user's...
Users who visit a web page for the first time select links on the basis of the link anchors and the descriptions of the links that are provided on the page. If these descriptions give an inaccurate impression of the underlying pages, users make incorrect choices. In this paper we present a novel algorithm to automatically detect links with problematic descriptions in hierarchical menus on the basis...
We present a new approach for performing load testing of Web applications by simulating realistic user behaviour with stochastic form-oriented analysis models. Realism in the simulation of user behaviour is necessary in order to achieve valid testing results. In contrast to many other user models, Web site navigation and time delay are modelled stochastically. The models can be constructed from sample...
