Automated Tool

In this chapter, a unified web accessibility assessment (UWAA) framework and its software has been proposed. UWAA framework was developed by considering Web Content Accessibility Guideline 2.0 to evaluate accessibility of web sites by integrating more than one evaluation approach. Achecker tool as an automated evaluation approach and barrier walkthrough (BW) as an expert-based evaluation approach were integrated in the UWAA framework. The framework also provides suggestions to recover from the problems determined to the evaluators. The websites of three universities were evaluated to determine the framework's accuracy and consistency. It was revealed that the results obtained from automated and expert-based evaluation methods were consistent and complementary with each other. Furthermore, it has been demonstrated that problems which cannot be determined by an automated tool but which can be detected by an expert can be identified by BW method.

The Web

The World Wide Web (the Web), a distributed hypermedia information system that provides global access to the Internet, has been most widely used for exchanging information, providing services, and doing business across national boundaries. It is difficult to find out exactly when the first multilingual Web site was up and running on the Internet, but as early as January 1, 1993, EuroNews, the first multilingual Web site in Europe, was launched to simultaneously cover world news from a European perspective in seven languages: English, French, German, Italian, Portuguese, Russian, and Spanish. (EuroNews, 2005). In North America, Web site multilinguality has become an important aspect of electronic commerce (e-commerce) as more and more Fortune 500 companies rely on the Internet and the Web to reach out to millions of customers and clients. Having a successful multilingual Web site goes beyond just translating the original Web content into different languages for different locales. Besides the language issue, there are other important issues involved in Web site multilinguality: culture, technology, content, design, accessibility, usability, and management (Bingi, Mir, & Khamalah, 2000; Dempsey, 1999; Hillier, 2003; Lindenberg, 2003; MacLeod, 2000). This article will briefly address the issues related to: (1) language that is one of the many elements conforming culture, (2) culture that greatly affects the functionality and communication of multilingual Web sites, and (3) technology that enables the multilingual support of e-commerce Web sites, focusing on the challenges and strategies of Web site multilinguality in global e-commerce.

This article evaluates online grocery shopping web sites catering to customers primarily in India. The process of evaluation has been carried out in 3 parts using Rapidminer. In part A, the authors have studied the similarity in content that resides on the grocery shopping web sites. Using unstructured data from homepage of grocery shopping websites and the keywords specified for the web sites, the authors have made an effort to establish a cosine similarity index amongst them. In part B, the authors have analysed the customer reviews from the web sites. Studying the resulting association rules, authors have attempted to identify the attributes that drive customer happiness. In part C, the authors have documented the web traffic metric parameters (attributes) measured by search engine optimization (SEO) tool web sites. Hence, the created a correlation matrix to determine the parameters that are significantly impacting per day revenue for the web sites.

Web server aims to service clients sensitively and clients wish to explore web sites at fast bandwidth. Nevertheless, sometimes users can only get the web content at a slow response due to the slow communication. Using data buffering technique, web cache provides clients an alternative way to acquire the web content from web server at low cost and high bandwidth. Using web cache technique, users can get fast response at low communication cost. When quantities of data are buffered to the cache server, cache policy becomes an important factor which can clearly affect the performance efficiency. Our contribution is that we take full account of the user's visiting action and redesign the cache policy. Based on this, we compare our policy (UVA) with existing method (LFU) through series of experiments. The results show that our method can efficiently improve cache hit rate.

Purpose – The purpose of this paper is to examine the extent to which accessibility is taken into account in the assessment and ranking of e-government web sites through the lens of a specific study related to Dubai e-government. Design/methodology/approach – The paper considers a case study related to Dubai e-government and it evaluates the accessibility of each of the 21 Dubai e-government web sites, based on the Web Content Accessibility Guidelines (WCAG) 2.0 and using an automated accessibility testing tool. A bivariate correlation analysis is performed to assess the correlation between web site ranking and accessibility score. Findings – The research reveals that contrary to common intuition and some earlier studies, there is a weak correlation between e-government web site ranking score and web site accessibility. Research limitations/implications – The paper uses an accessibility metric that is a proxy indicator of web accessibility and is not a real assessment of accessibility as experienced by a person with disability. Practical implications – When re-examined through the lens of Rawls's moral theory, this research suggests that accessibility should be given a higher priority in the general evaluation and ranking of e-government web sites. Social implications – The paper promotes universal accessibility to e-government information and services. Originality/value – The paper uses ethical arguments to highlight the need to comprehensively consider accessibility as a major criterion in the assessment and ranking of e-government web sites.

Finding one's way to sites of interest on the Web can be problematic, and this difficulty has been recently exacerbated by widespread development of 3-D Web content and virtual-world browser technology using the Virtual Reality Modeling Language (VRML). Whereas travelers can often navigate 2-D Web sites based on textual and 2-D thumbnail image representations of the sites' content, finding one's way to destinations in 3-D environments is notoriously troublesome. Wayfinding literature provides clear support for the importance of landmarks in building a cognitive map and then using that map to navigate in a 3-D environment, be it real or virtual. Textual and 2-D image landmark representations, however, lack the depth and context needed for travelers to reliably recognize 3-D landmarks. This paper describes a novel 3-D thumbnail landmark affordance called a worldlet. Containing a 3-D fragment of a virtual world, worldlets offer travelers first-person, multi-viewpoint experience with faithful representations of potential destinations. To facilitate an investigation into the comparative advantages of landmark affordances for wayfinding, worldlet capture algorithms were designed, implemented, and incorporated into two VRML-based virtual environment browsers. Findings from a psychological experiment using one of these browsers revealed that, compared to textual and image guidebook usage, worldlet guidebook usage: nearly doubled the time subjects spent studying the landmarks in the guidebook, significantly reduced the time required for subjects to reach landmarks, and reduced backtracking to almost zero. These results support the hypothesis that worldlets facilitate traveler landmark knowledge, expedite wayfinding in large virtual environments, and enable skilled wayfinding.
