Abstract

Web accessibility expresses the ease with which one can interact with a website effectively, regardless of disabilities and devices used. Despite the availability of relevant guidelines and technologies, many websites remain inaccessible. This may be due to the amount of manual effort required to ensure that a website conforms to web accessibility guidelines, such as the Web Content Accessibility Guidelines (WCAG). Software tools have been proposed to facilitate the process. However, these tools report many potential accessibility issues that require human judgment, and thus substantial manual resources. This paper investigates the effect of such potential issues reported by automated tools on web accessibility evaluation results. To this end, 441 university department websites were evaluated against WCAG 2 using the Siteimprove Accessibility Checker. Results found a significant effect of the manual inspection of potential issues on the accessibility results obtained. Regression analysis was used to predict the number of the semi-automatically identified accessibility issues based on the automatically identified ones.
