Usability study of a methodology based on concepts of ontology design to define website structures

Today, Web site design is used to make sites useful to users, with accessible functions, resources and information. Therefore, that design involves use of methodologies that allow an adequate structuring of them resources and organization, permitting users to access them quickly, easily and intuitively. This research consisted of a usability study oriented to website structure designers using a methodology based on concepts of ontology design. This study includes a planning to evaluate the design and the structure of website in aspects such as: ease of use, efficient access to information and performance on the tasks focused to total satisfaction of end user. Heuristic tests were used as diagnostic tools to evaluate usability of website design structures; these were supported by a heuristic evaluation guide and in the Sirius methodology[3]. The results obtained from them, allowed us to detect opportunities for improvement and optimization in website design, and in refining the Web interface oriented to end users.
