“…Brajnik et al [22] demonstrated the ability of expert users to detect accessibility violations with more reliability. However, Hong et al [23] conducted a study to compare web accessibility evaluation using human experts and automated software separately. The outcomes of their study showed that automated software tools have the ability to discover more accessibility errors than human experts.…”

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.

“…Hackett et al studied the accessibility of higher education websites to study the effect of technological advances and found that Higher education web sites become progressively inaccessible as complexity increases [26]. Kane et al analyzed the websites of top university websites and found that a large number of websites still have accessibility problems [28]. Hong et al examined the accessibility of Korean and U.S. government websites using the automated tools and then compared the results obtained by automated tools with that of human evaluation [28].…”

Accessibility refers to making websites usable for people of all types of abilities and disabilities, regardless of what browsing technology they are using. Since the web is an important resource of information for millions of people at all levels, accessible websites can help people with disabilities too to participate and contribute more actively in society. The objective of this study is to analyze the status of accessibility of banking websites as it allows people with disabilities to be independent and more in control of their own financial requirements. Web Content Accessibility Guidelines (WCAG) are universally accepted guidelines for website accessibility evaluation. The automatic evaluation tool is used to evaluate the website accessibility based on WCAG 1.0 and WCAG 2.0 guidelines. To further assess the reasons for accessibility barriers, complexity score was calculated. The accessibility score of different disability was also computed. The difference between the mean accessibility errors of public and private sector banks in India was also computed. The correlation of accessibility with the popularity and importance of the web sites was also evaluated. It was found that none of the websites that were evaluated were completely accessible to people with disabilities, i.e., there were no web sites that had no violations of web accessibility guidelines. There was no significant difference found in the accessibility of public and private sector banking websites in India. A framework to categorize the websites into fully accessible, partially accessible and inaccessible was also proposed.

“…Few institutions included accessibility features, which required manual verification. Hong et al (2008) in the paper on evaluating government web site accessibility entitled "Software tool vs human experts" provide insightful information about web accessibility based on human judgment in one Asian country (South Korea) in comparison to the USA. This study applies both the automated software tool and the human review of web content to measure web site accessibility.…”

Purpose -This paper aims to provide knowledge about methods used to evaluate the accessibility of Iranian web sites through a real research environment. Design/methodology/approach -The main theoretical base of this article is that almost all research conducted to evaluate the accessibility of web sites has used only one of three methods (namely manual, automatic and users' experiences). However, it seems that using a combination of these three methods is actually necessary. Consequently, taking a critical approach this article examines 18 Iranian ministerial web sites using the three methods. Findings -Findings in both documents and evaluative studies show that each of the methods has deficits and it is necessary to employ a combination of the methods in order to conduct a reliable accessibility assessment. The different rankings of ministerial web sites in various evaluations have confirmed this view. Originality/value -Identifying the advantages and disadvantages of the three methods and employing them in real research environments to assess the accessibility of ministerial web sites has been a useful exercise. The work can not only be a starting point for further discussions on the reliability of accessibility evaluation methods, but can also be applied to other types of web site.
