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.

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 Web

The Web is present in all fields of our life, from information and service Web pages to electronic public administration (e-government). Users of the Web are a heterogeneous and multicultural public, with different abilities and disabilities (visual, hearing, cognitive, and motor impairments). Web accessibility is about making websites accessible to all Internet users (both disabled and non-disabled). To assure and certify the fulfillment of Web accessibility guidelines, various accessibility evaluation methods have been proposed, and are classified in two types: qualitative methods (analytical and empirical) and quantitative methods (metric-based methods). As no method by itself is enough to guarantee full accessibility, many studies combine these qualitative and quantitative methods in order to guarantee better results. Some recent studies have presented combined evaluation methods between qualitative methods only, thus leaving behind the great power of metrics that guarantee objective results. In this chapter, a combined accessibility evaluation method based both on qualitative and quantitative evaluation methods is proposed. This proposal presents an evaluation method combining essential analytical evaluation methods and empirical test methods.

World Wide Web (WWW)also referred to as web acts as a vital source of information and searching over the web has become so much easy nowadays all thanks to search engines google, yahoo etc. A search engine is basically a complex multiprogram that allows user to search information available on the web and for that purpose, they use web crawlers. Web crawler systematically browses the world wide web. Effective search helps in avoiding downloading and visiting irrelevant web pages on the web in order to do that web crawlers use different searching algorithm . This paper reviews different web crawling algorithm that determines the fate of the search system.

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 content published on faculty web pages is an important source of information about the work of the faculty, which affects the performance of all student activities. It is therefore important to know what information is relevant to the student, as well as to what extent the content is published on the web site of the faculty in accordance with the needs of the student. Starting from the above, the subject of research of this paper is the content of the web sites of faculties of the University of Novi Sad. The main aim of the research is to determine whether there is and to what extent a certain content is present on the faculty web pages, as well as on the basis of the conducted research to provide suggestions for the improvement of web information in higher education.
