• Effects of sampling methods on web accessibility evaluations

  Giorgio Brajnik, Andrea Mulas, Claudia Pitton (2007) — Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '07)

  Brajnik, Mulas, and Pitton's Assets '07 paper is a large, careful empirical investigation of the sampling step in web-accessibility evaluation — the step at which an evaluator picks which pages of a site to actually test. For any site above a trivial…

• An Optimal Sampling Method for Web Accessibility Quantitative Metric

  Mengni Zhang, Can Wang, Jiajun Bu, Zhi Yu, Yi Lu, Ruijie Zhang, Chun Chen (2015) — Proceedings of the 12th International Web for All Conference (W4A 2015)

  This short paper proposes OPS-WAQM, an optimal page sampling method specifically designed for use with the Web Accessibility Quantitative Metric (WAQM) when evaluating large websites. The core problem is that evaluating every page of a large website …

• Active Learning for Web Accessibility Evaluation

  Mengni Zhang, Can Wang, Zhi Yu, Chao Shen, Jiajun Bu (2017) — Proceedings of the 14th International Web for All Conference (W4A)

  This paper introduces "active-prediction," a semi-supervised machine learning method that addresses a fundamental bottleneck in web accessibility evaluation: the prohibitive cost of evaluating all pages in a large website. Current practice relies on …
