A Declarative Model for Web Content Accessibility Evaluation Process

Providing a complete accessibility evaluation report of web platforms is certainly a complex task that requires effort and a certain level of knowledge about web prototypes. Due to the complexity of the web platform, accessibility criteria are frequently ignored by web designers and developers hindering the accessing opportunities of people who have special needs. Thus, the development of an advanced website accessibility evaluation tool is an emerging demand especially to provide complete accessibility reports considering every type of disability. The goal of this work is to develop a web accessibility evaluation tool to implement in real-life cases to evaluate website accessibility. Although, the existing web accessibility evaluation tools are effective, due to some limitations their reported results seem unclear for the end-user which could act as a prime factor to reduce the effectiveness of the tool. By addressing those vulnerabilities, our prime focus is to develop a web content accessibility testing tool focusing on five aspects to improve the limitations of the existing tools such as i) updated guideline implementation, ii) incorporate guideline simplification process, iii) consider user criteria as additional evaluation criteria, iv) categorize the report for textual and non-textual information and v) provide the overall accessibility report in terms of accessibility score of each disability type.
