In recent years we have witnessed a growing interest in adaptation and personalization in numerous application domains including business, education, and so forth. Applications that offer large bodies of information have in the Web era turned into systems with a significantly different nature than two decades ago. Think of the typical book catalog database from 20 years ago and the Web site of a book seller nowadays. A characteristic aspect of the restyling is the attention paid to the individual user. Technology has evolved and now allows application designers to include adaptation and personalization in the applications. This is especially important in the field of e-commerce, where users (customers) expect personalized services similar to those they receive in a conventional store. Typical e-commerce systems employ large bodies of information. In the case of a bookstore Web site, the designer defines an appropriate structure for the collection of books with all relevant properties. Generally, the design uses structures of concepts, where the concepts represent the actual information objects. The adaptation engineering is later performed on the level of these (abstract) concepts. We refer to these applications as concept-based systems. Adaptive concept-based systems are especially accepted in areas where the main goal is to tailor large amounts of information to the individual preference and knowledge state of the user. Besides electronic commerce, other examples include online museums (the visitor wandering through the collection on an individual basis) and e-learning applications (the student being involved with learning material in a way that the teacher thinks fits the student’s situation).

The effectiveness of an e-learning system for distance education to a large extent depends on the relevancy and presentation of learning content to the learner. The ability to gather documents on a particular topic from the web and adapt the contents of the document to suit the learner is an important task from the content creation perspective of e-learning. For the developer of e-learning material the provision to automatically extract, organize, and present content material would improve its effectiveness. This paper proposes to extract information from documents using language processing techniques and organizing the content into appropriate presentation slides for learning purposes using domain ontology and learning oriented pedagogy ontology.

Instructors recommend learning materials to a class of students not minding the learning ability and reading habit of each student. Learners are finding it problematic to make a decision about which available learning materials best meet their situation and will be beneficial to their course of study. In order to address this challenge, a new e-learning material recommender system that is able to recommend quality items to learners individually is required. The aim of this work is to develop a Personalized Recommender System that switches between Content-based and Collaborative filtering techniques, with an objective to design an algorithm to recommend electronic library materials, as well as personalize recommendations to both new and existing users. Experiments were conducted with evaluations showing that the recommender system was most effective when content-based filtering and collaborative filtering were used to recommend items for new users and existing users respectively, and still achieve personalization.

E-learning has the potential to be a very personalized experience and can be tailored to the individual involved. So far, science museums have yet to tap into this potential to any great extent, partly due to the relative newness of the technology involved and partly due to the expense. This chapter covers some of the speculative efforts that may improve the situation for the future, including the SAGRES project and the Ingenious Web site, among other examples. It is hoped that this will be helpful to science museums and centers that are considering the addition of personalization features to their own Web site. Currently, Web site personalization should be used with caution, but larger organizations should be considering the potential if they have not already started to do so.

This research project develops a framework for understanding how consumers interact with Web sites on the Internet. Our goal is to understand the interaction of individuals and Web sites from the perspective of the marketer, or third-party, who has created the site. Internet technology enables marketers to customize their interaction with consumers in order to better meet consumer needs. We are interested in whether and how this works. Our framework builds on four interdependent elements: first, the individual Internet user’s mindset as he/she enters a particular Web site, which includes, importantly, the user’s expectations; second, the Web site itself (consisting of four components: structure, content, connectivity, and malleability); third, the individual/Web site interaction; and fourth, the user’s evaluation of the Web site, which affects behavior.

Time Magazine argued in 2006 that the person of the year truly was “You”. This was in deed a significant gesture to the fact that digital technologies change the way people interact and live their lives. What made “You” a candidate for “Person of the year”, was that the development of the Internet had made it possible for anyone to publish and express your personality on the Web; or rather of “Web 2.0”. In 2007, the notion of “Web 2.0” has been on headlines for many conferences and conventions, articles and in the news. While some enthusiasts already prepare for the developments of “Web 3.0”, most people face the challenge of trying to grapple with how new technological changes affect their everyday life in the present tense. So, if “You” was the person of the year in 2006, Web 2.0 was the technology of the year in 2007. And then again, the notion of what consequences Web 2.0 might have for teaching and learning in the area of higher education, lifelong learning and adult education will be raised in numerous contexts. Some years ago, the Australian professor of teaching in Higher Education, Craig McInnis, described how most teachers in higher education felt that technological changes were among the most important factors affecting academic life. A report on the status of how Norwegian institutions have adopted ICT in teaching and learning, found that all institutions now use Learning Management Systems for their average teaching and administration tasks. Hence, the report concluded: the LMS has successfully brought the Norwegian academic into the digital age. The LMS is more or less synonymous with ICT. What worried the authors of the said report was that the use of the LMS was not considered sophisticated or innovative. Likewise, the influential report written by Zemsky and Massy (2004), found that much of the use was trivial and not primarily for the benefit of teaching and learning. We can predict that many teachers in higher education will think of Web 2.0 as the latest add-on to the burden of change that faces most teachers in higher education today. We can also predict that academics will adjust to these challenges as employees in most other organizations do: some will be innovators, some early adopters etc. The thing about Web 2.0 is that it is not possible to talk about a particular artefact, or a software or similar things. Some speak of web 2.0 as an “attitude”. One of the most practical solutions I have read has been suggested by David Brown, director of educational technology services at Dartmouth College. He acknowledges that those features commonly attributed to Web 2.0 technology correspond with present learning theories. Web 2.0 offers constructive creativity on the web in a new transparency that the present LMSs need to face: ”In short, the Web 2.0 models the very active engagement that is central to the learning paradigm.» Hence, the LMS need to develop into LMS 2.0. In the present issue we offer two articles that indirectly suggests that the current LMS have much to offer and that critical and creative users might push the limits of for what is possible. Laurence Habib and Monica Johannesen from Oslo University College, using Actor-Network theory in understanding the organisational and pedagogical effects of using the LMS, they offer us a dynamic interpretation on how the various actors shape and shake assumptions and limits of its use. Anne Karin Larsen, Grete Oline Hole and Martin Fahlvik from Bergen University College presents a tale about how they produced educational material with the goal of presenting it dynamically with the LMS, using the concept of a “Virtual Book”. The article discusses how the learning material contributes to students’ learning and how audio-visual learning material can contribute to good learning in e-learning courses. These articles correspond well to the journal’s aim to understand “ the promotion of participation and reflexivity in the social construction of the development of educational technology”. Larsen, Hole and Fahlvik demonstrate how this is a dynamic developmental process. The last paper has a different topic, but relates to the first article in the sense that if the technology is the same, different users approach it differently. The authors: Neil Anderson, Carolyn Timms and Lyn Courtney of James Cook University address the rural/urban distinction in a complex project, investigated in several aspects. If the difference is systematic and in conflict with educational and political aims, the alarm goes off. In this case the troubling news are that students in rural areas are less interested in adopting new technologies. References:Brown, D. (2007) Mashing up the Once and Future CMS. Educause Review.

Virtual communities (VCs) are places on the Web where people can find and then electronically ‘talk’ to others with similar interests. VCs primarily act as coffee shops, where people come and meet each other rather than focusing on content or commerce (Gupta & Kim, 2004). Still there are commercial ones where people can conduct transaction, auction, and commerce. The concept of a virtual community was born in 1993 when the Internet was first established in the United States (Rheingold, 1993). Today, virtual communities are more than just a means of connecting individuals and organisations. Today VCs acts as a business model employed by the digital economy for generating income, primarily through advertising (Reinhard & Wolkinger, 2002). Although virtual communities are still widely popular today, accounting for 84% of the Internet usage in 2002 (Horrigan, 2002), no one has yet agreed on a common definition for the term (Schoberth & Schrott, 2001). Schubert and Ginsberg (2000) defines a virtual community as a shared semantic space where individuals and organisations come together regularly to share common interests and values electronically. The definition varies depending upon the purpose served by the Web site. Based on a comprehensive research, Gupta and Kim (2004) developed a definition based on essential elements of a virtual community and define VC as a groups of like-minded strangers who interact predominantly in cyberspace to form relationships, share knowledge, have fun, or engage in economic transactions (Gupta & Kim, 2004). VCs play a bigger role in many aspects of a member’s life, from forming and maintaining friendships and romantic relationships, to learning, forming opinions, purchasing, and consuming products and services (Hagel & Armstrong, 1997). VCs are also ideal tools for e-commerce, marketing, knowledge building, and e-learning activities. Particularly, VCs add value by providing repeated points of contact which increase the stickiness of the Web site (Laudon & Traver, 2003). People love to interact on Internet and by facilitating their interaction users can be retained on site. The longer they are on site the greater are the chances of making the sale. How do these VCs exactly increase the stickiness of the Web site and how do they add business value to the Web site? To answer these questions we will visit hardwarezone.com (Appendix 1), a Singapore based virtual community which has been phenomenally successful since its inception. But before that we will briefly review the concept of stickiness.

In today’s modern world, the pace of technological development can be con-sidered exponential. Education must constantly adapt to this dynamic devel-opment. It must be able to innovate, to use modern tools and methods that are effectively integrated into the learning process. Education should provide an appropriate learning environment to meet changing needs, one way of which is e-learning. This environment can be an excellent support for the learning process; however, it will hardly be effective without developing the right student learning attitude. The e-learning environment gives freedom and independence to the individual, at the same time. For the learner's individual endeavor to be successfully completed as expected, control and continuous feedback are needed. One way to do this is through self-quizzing. Self-quizzes, divided into units, related to the learning material, with appropriate difficulty and amount, can help to understand and engrave the processed material, and thus improve the effectiveness of learning. Self-quizzes create the opportunity for imme-diate feedback, which is a very important feature of an e-learning environ-ment. According to many scientific research, immediate feedback can greatly help maintain interest and motivation, and quizzes are suitable tools for this purpose. In our research, we sought to answer the question of how the continuous, self-monitoring practice opportunity provided by online quizzes affects stu-dent achievement. In the case of an online course held at the University of Dunaújváros in 2019, we examined whether students who continuously per-form self-quizzes will be more effective by the end of the learning process than their peers who are less receptive to independent self-quizzing. We also addressed the effect of the nature of time spent on self-reflexive quizzing on learning success.
