Analysis of usability of universities Web portals using the Prometheus tool - SIRIUS

The aim of this paper is to present a heuristic study about the level of usability of 24 universities Web portals using data mining techniques. For experimenting in this work, we used a System for Evaluation of Usability of Web sites (SIRIUS) which contains a tool to generate usability valuations of Web sites called Prometheus and integrates 10 heuristics to do the process. The assessments collected will give feedback to IT departments to redesign, restructure or implement new Web portals that comply with the standards of usability.
