Abstract: The development, analysis and follow-up of the processes designed to assure the usability and accessibility of websites is a tedious work for the moderator or evaluator. This is why there is a necessity for tools that can automate the processes. There are some tools that cover some of the technical aspects, but no tools have been identified that can tackle the process as a whole. For these reasons the Aragonese Usability Laboratory decided to develop WebA (Web Analysis), with the objective to have a complete application. This application is designed through modules with the objective of covering all of the evaluation and analysis phases, and it concludes with a process management module. For the analysis phase a Card Sorting module (open & closed) has been developed that uses the hierarchical and multidimensional cluster analysis, which allows a better information architecture. For the evaluation phases, modules have been developed that allow the semiautomatic evaluation of usability through user satisfaction tests based on Nielsen heuristics and ISO standards, the evaluation of accessibility through the verification of WCAG 1.0 guidelines. The application concludes with a process design and evaluation management module, and modules that automatically generate the reports of the analysis carried out.

Keywords: accessibility of websites, human computer interaction, usability engineering, website usability evaluation
