Markel Vigo, Myriam Arrue, Giorgio Brajnik, Raffaella Lomuscio, Julio Abascal
2007 Proceedings of the 2007 international cross-disciplinary conference on Web accessibility (W4A) - W4A '07  
This paper raises the need for quantitative accessibility measurement and proposes three different application scenarios where quantitative accessibility metrics are useful: Quality Assurance within Web  ...  Therefore, we conclude that the metric is reliable for ranking purposes in Information Retrieval and accessibility monitoring scenarios and can also be partially applied in a Web Engineering scenario.  ...  In this paper we propose and validate a quantitative metric for measuring accessibility of web sites. The proposed metric is automatically calculated from the output of evaluation tools.  ...
