Hypertext/hypermedia systems and user-model-based adaptive systems in the areas of learning and information retrieval have for a long time been considered as two mutually exclusive approaches to information access. Adaptive systems tailor information to the user and may guide the user in the information space to present the most relevant material, taking into account a model of the user's goals, interests and preferences. Hypermedia systems, on the other hand, are `user neutral': they provide the user with the tools and the freedom to explore an information space by browsing through a complex network of information nodes. Adaptive hypertext and hypermedia systems attempt to bridge the gap between these two approaches. Adaptation of hypermedia systems to each individual user is increasingly needed. With the growing size, complexity and heterogeneity of current hypermedia systems, such as the World Wide Web, it becomes virtually impossible to impose guidelines on authors concerning the overall organization of hypermedia information. The networks therefore become so complex and unstructured that the existing navigational tools are no longer powerful enough to provide orientation on where to search for the needed information. It is also not possible to identify appropriate pre-defined paths or subnets for users with certain goals and knowledge backgrounds since the user community of hypermedia systems is usually quite inhomogeneous. This is particularly true for Web-based applications which are expected to be used by a much greater variety of users than any earlier standalone application. A possible remedy for the negative effects of the traditional `one-size-fits-all' approach in the development of hypermedia systems is to equip them with the ability to adapt to the needs of their individual users. A possible way of achieving adaptivity is by modeling the users and tailoring the system's interactions to their goals, tasks and interests. In this sense, the notion of adaptive hypertext/hypermedia comes naturally to denote a hypertext or hypermedia system which reflects some features of the user and/or characteristics of his system usage in a user model, and utilizes this model in order to adapt various behavioral aspects of the system to the user. This book is the first comprehensive publication on adaptive hypertext and hypermedia. It is oriented towards researchers and practitioners in the fields of hypertext and hypermedia, information systems, and personalized systems. It is also an important resource for the numerous developers of Web-based applications. The design decisions, adaptation methods, and experience presented in this book are a unique source of ideas and techniques for developing more usable and more intelligent Web-based systems suitable for a great variety of users. The practitioners will find it important that many of the adaptation techniques presented in this book have proved to be efficient and are ready to be used in various applications.

In his widely acclaimed book Hypertext George P. Landow described a radically new information technology and its relationship to the work of such literary theorists as Jacques Derrida and Roland Barthes. Now Landow has brought together a distinguished group of authorities to explore more fully the implications of hypertextual reading for contemporary literary theory. Among the contributors, Charles Ess uses the work of Jürgen Habermas and the Frankfurt School to examine hypertext's potential for true democratization. Stuart Moulthrop turns to Deleuze and Guattari as a point of departure for a study of the relation of hypertext and political power. Espen Aarseth places hypertext within a framework created by other forms of electronic textuality. David Kolb explores what hypertext implies for philosophy and philosophical discourse. Jane Yellowlees Douglas, Gunnar Liestol, and Mireille Rosello use contemporary theory to come to terms with hypertext narrative. Terrence Harpold investigates the hypertextual fiction of Michael Joyce. Drawing on Derrida, Lacan, and Wittgenstein, Gregory Ulmer offers an example of the new form of writing hypertextuality demands.

This innovative monograph focuses on a contemporary form of computer-based literature called 'literary hypertext', a digital, interactive, communicative form of new media writing. Canonizing Hypertext combines theoretical and hermeneutic investigations with empirical research into the motivational and pedagogic possibilities of this form of literature. It focuses on key questions for literary scholars and teachers: How can literature be taught in such a way as to make it relevant for an increasingly hypermedia-oriented readership? How can the rapidly evolving new media be integrated into curricula that still seek to transmit 'traditional' literary competence? How can the notion of literary competence be broadened to take into account these current trends? This study, which argues for hypertext's integration in the literary canon, offers a critical overview of developments in hypertext theory, an exemplary hypertext canon and an evaluation of possible classroom applications.

Abstract: "Analyzing the structure of a hypertext database can give useful information to the traveler in hyperspace. We present a preliminary collection of structural tools for users of hypertext systems. These tools can suggest answers to questions like: Where am I? How can I choose and get to my destination? What else is in my current neighborhood? etc. Structure is imposed on the hypertext by using two processes: hierarchization and cluster identification. Several metrics are presented and used in the above processes for locating landmarks and getting global information on the hypertext structure. The structural analysis is integrated with previous attempts to reduce the users' disorientation while navigating the hyperspace. An integration with fisheye views and tree-maps is presented."
