• DOM block clustering for enhanced sampling and evaluation

  Simon Harper, Anwar Ahmad Moon, Markel Vigo, Giorgio Brajnik, Yeliz Yesilada · 2015 · Proceedings of the 12th International Web for All Conference (W4A)

  This paper addresses a fundamental challenge in web accessibility evaluation: large websites with thousands or tens of thousands of pages are practically impossible to fully evaluate, yet current sampling methods (random, best-guess, or convenience samples) cannot be trusted…

• A Macroscopic Web Accessibility Evaluation at Different Processing Phases

  Nádia Fernandes, Luís Carriço · 2012 · Proceedings of the International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper investigates a fundamental question about automated accessibility evaluation: does it matter whether you evaluate a web page as it arrives from the server (before browser processing) or as the user actually experiences it (after browser processing, including…

• Evaluating the Accessibility of Rich Internet Applications

  Nádia Fernandes, Daniel Costa, Sergio Neves, Carlos Duarte, Luís Carriço · 2012 · Proceedings of the International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper addresses a critical gap in automated accessibility evaluation: most tools only assess the initial HTML served to the browser, missing the dynamically generated content that defines modern Rich Internet Applications (RIAs). Web applications using JavaScript and AJAX…
