- We examined the consequences of a visualization pattern often chosen by web sites which show textual information within the web pages and the related iconic information within pop-up windows. The information visualization in pop-up windows aims to integrate text and pictures but makes difficult the analysis of both information resources. We conducted an experiment in which 80 participants read on a computer screen a text with embedded graphs either near (to the related textual information) or far (from it), plus graphs were integrated in the text or within pop-up windows. The reading behaviour of participants was observed to establish who, among them, examined the graphs and who did not. The recall for textual and iconic information was measured using a recall questionnaire. Our pattern of data shows a student's tendency to ignore graphs, in particular when they are visualized in pop-up windows. These results are confirmed by interviews to undergraduate students who analyzed the same materials using thinking aloud method.

Chapter 8 explores the arrival of the World Wide Web, Amazon, and Google. The web allows users to display “pages” of information retrieved from remote computers by means of the Internet. Inventor Tim Berners-Lee released the first web software for free, setting in motion an explosion in Internet usage. Seeing the opportunity of a lifetime, Jeff Bezos set-up Amazon as an online bookstore. Amazon’s success was accelerated by a product recommender algorithm that selectively targets advertising at users. By the mid-1990s there were so many web sites that users often couldn’t find what they were looking for. Stanford PhD student Larry Page invented an algorithm for ranking search results based on the importance and relevance of web pages. Page and fellow student, Sergey Brin, established a company to bring their search algorithm to the world. Page and Brin - the founders of Google - are now worth US$35-40 billion, each.

In this era of Web computing, Cyber Security is very important as more and more data is moving into the Web. Some data are confidential and important. There are many threats for the data in the Web. Some of the basic threats can be addressed by designing the Web sites properly using Search Engine Optimization techniques. One such threat is the hanging page which gives room for link spamming. This chapter addresses the issues caused by hanging pages in Web computing. This Chapter has four important objectives. They are 1) Compare and review the different types of link structure based ranking algorithms in ranking Web pages. PageRank is used as the base algorithm throughout this Chapter. 2) Study on hanging pages, explore the effects of hanging pages in Web security and compare the existing methods to handle hanging pages. 3) Study on Link spam and explore the effect of hanging pages in link spam contribution and 4) Study on Search Engine Optimization (SEO) / Web Site Optimization (WSO) and explore the effect of hanging pages in Search Engine Optimization (SEO).

How can three linguistical methods be used to identify the Web displays of an organization’s knowledge values and knowledge-sharing requirements? This chapter approaches this question by using three linguistical methods to analyse a company’s Web sites; (a) elements from the community of practice theory (CoP), (b) concepts from communication theory, such as modality and transitivity, and (c) elements from discourse analysis. The investigation demonstrates how a company’s use of the Web can promote a work attitude that actually can be considered as an endorsement of a particular organizational behaviour. The Web pages display a particular organizational identity that will be a magnet for some parties and deject others. In this way, a company’s Web pages represent a window to the world that need to be handled with care, since this can be interpreted as a projection of the company’s identity.

As I examined hundreds of Web sites promising electronic or Web portfolio data for this text, and performed observations and interviews with dozens of students and colleagues, I discovered some exemplary cases of Web portfolio usage. The Web portfolio phenomena and the rise in electronic portfolio development within all disciplines have prompted academic institutions to develop Web portfolio programs and to push these programs towards faculty and students. My general observations are that the institutions that make serious efforts to develop and manage a sound electronic portfolio program are getting good results. Right now, it is not conceivable for an institution to be able to have 100 percent of their student and faculty populations to have Web portfolios. At Penn State University, in the Dutton E-Education Institute, they are trying by providing 500 MB of Web portfolio space to all undergraduate students while enrolled. The institute recently reported in December 2004 that one in three undergraduate students activate their Web portfolio and use it for academic reflection and professional purposes. The Dutton Institute and Penn State’s e-portfolio initiative are highlighted further in this chapter. During interviews with students and faculty members who have created Web portfolios, I discovered some interesting themes that included fear of copyright infringement, technical worries, and lack of process knowledge. These themes encompass problems and positive events that shaped each Web portfolio authors experiences and these are also discussed later in the chapter. Also in this chapter, a Web-based e-portfolio program proposal sample is included to give you a head start on creating a proposal for your institution or program. The sample is based on criteria for new technology proposals distributed by an academic vice president at a four-year university. It is not meant to be a one-size-fits-all proposal. It is meant to give structure to developing an initial program concept. Proposal adaptation based on discipline, industry, and curriculum would certainly be needed. Finally, electronic portfolios are widely seen in the discipline of education. This chapter provides observations of teacher Web portfolios which include all levels of educators from elementary through higher education. These cases seem to have exemplary qualities that fit the teacher Web portfolio and can be transcended into the creation of Web portfolios in any discipline. The goal of examining these cases is to identify important components in the Web portfolios of teachers that represent evidence of professional development, project and skill sets, and persuasion. These teacher Web portfolio cases are effective models for use in any discipline.

The power of the World Wide Web, it is commonly believed, lies in the vast information it makes available; "Content is king," the mantra runs. This image creates the conception of the Internet as most of us envision it: a vast, horizontal labyrinth of pages which connect almost arbitrarily to each other, creating a system believed to be "democratic" in which anyone can publish Web pages. I am proposing a new, vertical and hierarchical conception of the Web, observing the fact that almost everyone searching for information on the Web has to go through filter Web sites of some sort, such as search engines, to find it. The Albert Einstein Online Web site provides a paradigm for this re-conceptualization of the Web, based on a distinction between the wealth of information and that which organizes it and frames the viewers' conceptions of the information. This emphasis on organization implies that we need a new metaphor for the Internet; the hierarchical "Tree" would be more appropriate organizationally than a chaotic "Web." This metaphor needs to be changed because the current one implies an anarchic and random nature to the Web, and this implication may turn off potential Netizens, who can be scared off by such overwhelming anarchy and the difficulty of finding information.

Social networking is one of the most recently used technologies because of its advantages, spread and interaction. It is one of the most prominent applications of the second generation Web 2.0, which has effectively imposed itself on the users of the internet. Facebook network comes second after search engine at the global level, "Google". It is noted that they are highly efficient in providing information services and representation of information institutions and facilities in the virtual world. it is agreed that the progress of the societies is measured according to their ability to free and fast access to information and to use it to generate knowledge that reaches wisdom, progress and excellence. At this point, the importance of studies of information is shown in general and Webometrics in particular, which means that the set of statistical methods and measurements used to study the quantitative and qualitative aspects of information resources, structures, uses and techniques on the web, is found to be bibliometric studies designed to study and analyze reference citations, can be applied to the information resources available on the web such as the links of web pages and the use of those sites. Therefore, the study aims to monitor students' attitudes towards the use of social networking sites in general, and the Facebook page of the department of information studies of the Libyan Academy particularly. To identify the view of the students of the information management division and the management of the archive to their identify satisfaction with the information services provided by the page, and the extent of knowledge of the links of electronic sources of information, and the extent to meet their needs and scientific desires, and to what extent related to academic and research interests.

The Internet and the World Wide Web are growing at unprecedented rates. More and more teachers are authoring school or classroom web pages. Such pages have particular potential for use in rural areas by special educators, children with special needs, and the parents of children with special needs. The quality of many of these pages leaves much to be desired. All web pages, especially those authored by special educators should be accessible for people with disabilities. Many other problems complicate use of the web for all users, whether or not they have disabilities. By taking some simple steps, beginning webmasters can avoid these problems. This article discusses practical solutions to common accessibility problems and other problems seen commonly on the web.

This chapter will address the issues of Uniform Resource Locator (URL) correction techniques in proxy servers. The proxy servers are more and more important in the World Wide Web (WWW), and they provide Web page caches for browsing the Web pages quickly, and also reduce unnecessary network traffic. Traditional proxy servers use the URL to identify their cache, and it is a cache-miss when the request URL is non-existent in its caches. However, for general users, there must be some regularity and scope in browsing the Web. It would be very convenient for users when they do not need to enter the whole long URL, or if they still could see the Web content even though they forgot some part of the URL, especially for those personal favorite Web sites. We will introduce one URL correction mechanism into the personal proxy server to achieve this goal.

Although many of the initial hopes regarding the Internet's effect on political engagement and participation has largely gone unfulfilled, it is generally held that the Internet still plays substantial role in political campaigns. Several studies have focused on how the Internet is employed for such purposes during an actual election campaign, but rather few studies have adopted a broader temporal scope, examining Web sites of political parties before, during and after an election. This paper fills this research gap by presenting a longitudinal analysis of the Web sites of Swedish political parties during the election year of 2010. Starting in January of 2010, these Web pages were downloaded on a monthly basis, a practice continued until the end of the year. By studying the Web sites of political parties before, during and after an election campaign, this project provides unique insights into Web campaigning rationale.
