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.

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.

The purpose of the article is to assess the accessibility of electronic educational resources (EER) published in the university Moodle Learning Management System (LMS). The analysis involved 22 EERs in mathematical and information technology disciplines, located in the Moodle LMS of the V. I. Vernadsky Crimean Federal University. The examination algorithm included analysis using the Web Accessibility Evaluation Tool (WAVE) and expert analysis of web accessibility using visual, auditory and manual methods based on 89 checklist attributes. In the result of the analysis, multiple accessibility errors of the Moodle platform and the EERs hosted on it were found. The most serious platform problems include: lack of compatibility with text browsers; errors of reproduction by screen readers; errors of content reproduction on mobile devices. The list of accessibility errors made by the authors of EERs includes: incorrect design of hyperlinks (22.7 % of the EERs); lack of subtitles (13.6 %), transcripts (22.7 %), synopses of video lectures (27.3 %); lack of alternative descriptions for figures (68.2 %); time limit for tests (9.1 %); lack of special markup for mathematical notation (36.4 %) and program code (13.6 %), etc. Results of the survey show need in training of EERs’ authors in technologies for developing accessible educational web content. It is advisable to familiarize web developers deploying an LMS at universities with the basics of web accessibility, LMS accessibility functions and modules in order to select the most suitable platform, determine and install the required set of accessibility tools. Before launching all EERs should be subject to mandatory examination for compliance with the web accessibility guidelines.

The Web

Web Accessibility is a hot topic today. Striving for social inclusion has resulted in the requirement of providing accessible content to all users. However, since each user is unique, and the Web evolves in a decentralized way, little or none is known about the shape of the Web’s accessibility on its own at a large scale, as well as from the point-of-view of each user. In this chapter the authors present the Web Accessibility Knowledge Framework as the foundation for specifying the relevant information about the accessibility of a Web page. This framework leverages Semantic Web technologies, side by side with audience modeling and accessibility metrics, as a way to study the Web as an entity with unique accessibility properties dependent from each user’s point of view. Through this framework, the authors envision a set of queries that can help harnessing and inferring this kind of knowledge from Web graphs.

With the rapidly growing demand for corporate information from the external stakeholders, the Internet is a crucial instrument for meeting the required information. The web-based disclosure is an improvised version of the traditional form of disclosure with enhanced technology. In spite of that, web-based disclosure is the most prevalent form of business communication, and the accessibility of corporate information on webpages is a concern area for the organization. Thus, this article is an attempt to study the web accessibility of corporate information disclosed by 100 large BSE listed Indian companies and also to identify the firm determinants that affect the web accessibility of corporate information. The study reveals that the web-accessibility of the company website is increased with company size and company listing age. It also shows that companies with a low market risk have more concerns for the web accessibility of corporate information. The results of the study are helpful for the organizations to make policies for the advancement of web accessibility on the webpages.
