چکیده

A novel metric for quantitatively measuring the severity of websites barriers that limit the accessibility for disabled people is proposed. The metric is based on the Web Content Accessibility Guidelines (WCAG 2.0), which is the most adopted voluntary web accessibility standard internationally that can be tested automatically. The proposed metric is intended to rank the accessibility barriers based on their severity rather than the total conformance to priority levels. Our metric meets the requirements as a measurement for scientific research. An experiment is conducted to assess the results of our metric and to reveal the commonplace violations that persist in websites and affect disabled people interacting with the web.

Explicit syntax and implicit semantics of Web coding are typically addressed as distinct dominions in providing metrics for content accessibility. A more down-to-earth portrait about barriers and their impact on users with disabilities could be obtained whether any quantitative synthesis about number and size of barriers integrated measurements from automatic checks and human assessments. In th...
