Automated Evaluation of Web Site Accessibility Using A Dynamic\n Accessibility Measurement Crawler

Achieving accessibility compliance is extremely important for many government\nagencies and businesses who wish to improve services for their consumers. With\nthe growing reliance on dynamic web applications many organizations are finding\nit difficult to implement accessibility standards, often due to the inability\nof current automated testing tools to test the stateful environments created by\ndynamic web applications. In this paper, we present mathematical foundations\nand theory for the Demodocus framework and prototype, and outline its approach\nto using web science, web crawling,and accessibility testing to automatically\nnavigate and test interactive content for accessibility. Our approach simulates\nthe page interactions of users with and without disabilities, and compares\ngraphs of reachable states from these simulations to determine both the\naccessibility and the difficulty of content access for these different users.\n
