With the growth of e-services in the past two decades, the concept of web accessibility has been given attention to ensure that every individual can benefit from these services without any barriers. Web accessibility is considered one of the main factors that should be taken into consideration while developing webpages. Web Content Accessibility Guidelines 2.0 (WCAG 2.0) have been developed to guide web developers to ensure that web contents are accessible for all users, especially disabled users. Many automatic tools have been developed to check the compliance of websites with accessibility guidelines such as WCAG 2.0 and to help web developers and content creators with designing webpages without barriers for disabled people. Despite the popularity of accessibility evaluation tools in practice, there is no systematic way to compare the performance of web accessibility evaluators. This paper first presents two novel frameworks. The first one is proposed to compare the performance of web accessibility evaluation tools in detecting web accessibility issues based on WCAG 2.0. The second framework is utilized to evaluate webpages in meeting these guidelines. Six homepages of Saudi universities were chosen as case studies to substantiate the concept of the proposed frameworks. Furthermore, two popular web accessibility evaluators, Wave and SiteImprove, are selected to compare their performance. The outcomes of studies conducted using the first proposed framework showed that SiteImprove outperformed WAVE. According to the outcomes of the studies conducted, we can conclude that web administrators would benefit from the first framework in selecting an appropriate tool based on its performance to evaluate their websites based on accessibility criteria and guidelines. Moreover, the findings of the studies conducted using the second proposed framework showed that the homepage of Taibah University is more accessible than the homepages of other Saudi universities. Based on the findings of this study, the second framework can be used by web administrators and developers to measure the accessibility of their websites. This paper also discusses the most common accessibility issues reported by WAVE and SiteImprove.

The huge development in the websites and continuous exchange of the information led to more consideration of the websites accessibility. There are many accessibility-based on studies conducted throughout the world. However, the existing literature lacks a study on the assessment of accessibility to the Iraqi universities websites. Accordingly, this study measured the accessibility to websites of 36 Iraqi public universities listed in the official webpage of the Iraqi Ministry of Higher Education. Furthermore, it explored the relationships among three free web accessibility tools, namely Web Accessibility Versatile Evaluator, EIII Page Checker and Access Monitor, to test their agreement in terms of the accessibility results. These three free tools were used to evaluate the accessibility of the Iraqi universities websites. Statistical Package for the Social Sciences was used to analyze the results. The results of the three tools showed that the issue of accessibility is ignored by the webmasters of websites under the study. In addition, this study presented agreement among the three tools in terms of results.   http://dx.doi.org/10.25130/tjps.24.2019.060

The Web

The web has become the primary source of information for many people. Many services are provided on the web. Despite extensive guidelines for the accessibility of web pages, many websites are not accessible, making these websites difficult or impossible to use for people with disabilities. Evaluating the accessibility of web pages can either be done manually, which is a very laborious task, or by using automated tools. Unfortunately, the results from different tools are often inconsistent because of the ambiguity of the current guidelines. In this paper, a declarative approach for describing the requirements for accessible web pages is presented. This declarative model can help developers of accessibility evaluation tools to create tools that produce more consistent results and are easier to maintain.

Resumen El siguiente artículo presenta un análisis sobre pautas, métodos y herramientas de evaluación de accesibilidad web, tomando como referencia las WCAG 2.0, estándar de la W3C. Además, se estudian los diferentes tipos de discapacidad y limitaciones de acceso. También se muestran los principales beneficios de la accesibilidad, los siete principios del diseño web para todos que comprenden la base de la accesibilidad y un breve análisis sobre las WCAG 2.0 y sus niveles y criterios de conformidad. Finalmente, se considera los métodos de evaluación manual y automática, con algunos ejemplos de herramientas de validación basadas en la normativa de la W3C. Este análisis tiene el objetivo de ayudar a concientizar sobre la necesidad del diseño y desarrollo de sitios web accesibles, y a la vez promover las recomendaciones de la W3C para tales fines. Palabras claveaccesibilidad web, discapacidad, diseño universal, pautas WCAG 2.0.   Abstract The following paper presents an analysis on guidelines, methods and evaluation tools of web accessibility, taking the WCAG 2.0, standard of the W3C as a reference. In addition, it studies the different types of disability and access limitations. It also shows the main benefits of the accessibility, the seven web design for all principles that contain the base of accessibility and also presents an analysis about the WCAG 2.0 guidelines and his conformity levels and success criteria. Finally, both evaluation methods, manual and automatic are considered, and some examples of validation tools based on the W3C regulation. This analysis has the goal to help to create conscience on the need to design and develop accessible web sites, and simultaneously to announce the W3C recommendations to achieve it.Keywordsweb accessibility, disability, universal design, WCAG 2.0 guidelines
