This paper describes how the web content visualization can be greatly improved using the modeling technique. Web content visualization is the outcome of effort made to avail an improved 3D visualization unlike the 2D web content visualization at present. Web page navigation in this case will be depicted by a 2D graph and the web content will be visualized in the form of 3D graph. Also the RSS feeds will be visualized in the form of 3D graph. In normal browser we type name of the URL in the address bar and that URL is downloaded. But the 3D browser takes any URL as an input and generates a 3D graph of the whole website. When we type the URL, a root node of this URL is created. And then this URL goes to the Parser. The parser, parse this web page and gives output in the form of the set of the hyperlinks. Corresponding to each link we create a node and it is attached to the root node. In this way the whole 3D graph of the website is generated. Different color schemes are used for the nodes of different links e.g. text links, image links, video links etc. Advanced search facility is also provided. Moreover as the graph is 3D in nature, the user can rotate the graph as per his requirement.

The Web

With the Web 2.0 paradigm, a huge volume of Web content is generated by users at online forums, wikis, blogs, and social networks, among others. These user-contributed contents include numerous user opinions regarding products, services, or political issues. Among these user opinions, certain comparison opinions exist, reflecting customer preferences. Mining comparison opinions is useful as these types of viewpoints can bring more business values than other types of opinion data. Manufacturers can better understand relative product strengths or weaknesses, and accordingly develop better products to meet consumer requirements. Meanwhile, consumers can make purchasing decisions that are more informed by comparing the various features of similar products. In this paper, a novel Support Vector Machine-based method is proposed to automatically identify comparison opinions, extract comparison relations, and display results with the comparison relation maps by mining the volume of consumer opinions posted on the Web. The proposed method is empirically evaluated based on consumer opinions crawled from the Web. The initial experimental results show that the performance of the proposed method is promising and this research opens the door to utilizing these comparison opinions for business intelligence.

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.

Web services are an emerging technology that has attracted much attention from both the research and the industry sectors in recent years. The exploitation of Web services as components in Web applications facilitates development and supports application interoperability, regardless of the programming language and platform used. However, existing Web services development standards do not take into account the fact that the provided content and the interactive functionality should be accessible to, and easily operable by, people with disabilities. This chapter presents a platform named myWebAccess, which provides a mechanism for the semi-automated “repair” of Web services' interaction characteristics in order to support the automatic generation of interface elements that conform to the de facto standard of the Web Content Accessibility Guidelines 2.0. myWebAccess enhances interaction quality for specific target user groups, including people with visual and motor disabilities, and supports the use of Web services on diverse platforms (e.g., mobile phones equipped with a browser). The Web developers can build their own design templates and the users of myWebAccess can create a personalized environment containing their favourite services. Thus, they can interact with them through interfaces appropriate to their specific individual characteristics.

With the growing popularity of online services that allow individuals to consume and contribute Web content with social groups of self-selected affiliates, the socio-technical geography of the Web has become increasingly complex. To map some of this space in a productive way for organizations and online researchers, we focus our attention on a particular segment of Web 2.0 services, publicly available online services (PAOSs) used for work purposes. After defining this segment and its relationship to other kinds of online services, we report the results of an annual survey that looks at who is using such PAOSs for work as well as the nature of that work. As our survey results indicate, how often PAOSs are used for work differs depending on the company size and office location of individuals. To frame our findings, we differentiate among the multiple PAOSs that respondents report using by classifying them as different genres of services, which we find provides a productive typology for understanding such services and their roles in organizations.

The Web

The World Wide Web is a part of the Internet that provides data dissemination facility to people. The contents of the Web are crawled and indexed by search engines so that they can be retrieved, ranked, and displayed as a result of users' search queries. These contents that can be easily retrieved using Web browsers and search engines comprise the Surface Web. All information that cannot be crawled by search engines' crawlers falls under Deep Web. Deep Web content never appears in the results displayed by search engines. Though this part of the Web remains hidden, it can be reached using targeted search over normal Web browsers. Unlike Deep Web, there exists a portion of the World Wide Web that cannot be accessed without special software. This is known as the Dark Web. This chapter describes how the Dark Web differs from the Deep Web and elaborates on the commonly used software to enter the Dark Web. It highlights the illegitimate and legitimate sides of the Dark Web and specifies the role played by cryptocurrencies in the expansion of Dark Web's user base.

3D Content

The implementation of virtual and augmented reality environments on the web requires integration between 3D technologies and web technologies, which are increasingly focused on collaboration, annotation, and semantics. Thus, combining VR and AR with the semantics arises as a significant trend in the development of the web. The use of the Semantic Web may improve creation, representation, indexing, searching, and processing of 3D web content by linking the content with formal and expressive descriptions of its meaning. Although several semantic approaches have been developed for 3D content, they are not explicitly linked to the available well-established 3D technologies, cover a limited set of 3D components and properties, and do not combine domain-specific and 3D-specific semantics. In this chapter, the authors present the background, concepts, and development of the Semantic Web3D approach. It enables ontology-based representation of 3D content and introduces a novel framework to provide 3D structures in an RDF semantic-friendly format.
