Book Description
Information Retrieval (IR) has concentrated on the development of information management systems to support user retrieval from large collections of homogeneous textual material. A variety of approaches have been tried and tested with varying degrees of success over many decades of research. Hypertext (HT) systems, on the other hand, provide a retrieval paradigm based on browsing through a structured information space, following pre-defined connections between information fragments until an information need is satisfied, or appears to be. Information Retrieval and Hypertext addresses the confluence of the areas of IR and HT and explores the work done to date in applying techniques from one area, to the other leading to the development of `hypertext information retrieval' (HIR) systems. An important aspect of the work in IR/HT and in any user-centred information system is the emergence of multimedia information and such multimedia information is treated as an integral information type in this text. The contributed chapters cover the development of integrated hypertext information retrieval models, and the application of IR and HT techniques in hypertext construction and the approaches that can be taken in searching HIR systems. These chapters are complemented by two overview chapters covering, respectively, information retrieval and hypertext research and developments. Information Retrieval and Hypertext is important as it is the first text to directly address the combined searching/browsing paradigm of information discovery which is becoming so important in modern computing environments. It will be of interest to researchers and professionals working in a range of areas related to information discovery.

Book Description
This text presents a theoretical and practical examination of the latest developments in Information Retrieval and their application to existing systems. By starting with a functional discussion of what is needed for an information system, the reader can grasp the scope of information retrieval problems and discover the tools to resolve them. The book takes a system approach to explore every functional processing step in a system from ingest of an item to be indexed to displaying results, showing how implementation decisions add to the information retrieval goal, and thus providing the user with the needed outcome, while minimizing their resources to obtain those results. The text stresses the current migration of information retrieval from just textual to multimedia, expounding upon multimedia search, retrieval and display, as well as classic and new textual techniques. It also introduces developments in hardware, and more importantly, search architectures, such as those introduced by Google, in order to approach scalability issues. About this textbook: A first course text for advanced level courses, providing a survey of information retrieval system theory and architecture, complete with challenging exercises Approaches information retrieval from a practical systems view in order for the reader to grasp both scope and solutions Features what is achievable using existing technologies and investigates what deficiencies warrant additional exploration

Book Description
The hypermedia authoring process has been vividly described in a special issue of the Economist as a combination of writing a book, a play, a film, and a radio or television show: A hypermedia document combines all these elements and adds some of its own. The author' s first job is to structure and explain all of the infor mation. The author then must distill the information into brief, descriptive nodes. Each node has to contain a Iist of the ingredients, and instructions on how the ingredients are mixed together to the greatest advantage. The structure of the material provided is translated into an architectural metaphor of some kind; much of the designer' s work is the creation of this imaginary space. Then, the designers must chart the details of what to animate, what to film, who to inter view, and how to arrange the information in the space tobe built [Eco95a]. This book presents guidelines, tools, and techniques for prospective authors such that they can design better hypermedia documents and applications. lt surveys the different techniques used to organize, search, and structure infor mation in a large information system. It then describes the algorithms used to locate, reorganize, and link data to enable navigation and retrieval. It Iooks in detail at the creation and presentation of certain types of visual information, namely algorithm animations. It introduces new mechanisms for editing audio and video data streams.

Book Description
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.

Book Description
This volume is a record of the first Eurographics Workshop on Multimedia, held at the department of Numerical Analysis and Computing Science (NADA), Royal Institute of Technology, Stockholm, April 18-19, 1991. Eurographics is the European Association for Computer Graphics. It is a non-profit organization, one of whose activities is organizing workshops to provide an interface between academic and industrial research in the field of computer graphics. The idea of holding a Eurographics workshop on multimedia was put forward at the Eurographics conference in 1989. Following the success of this first workshop, a second workshop has been announced, to take place in Darmstadt, May 4-6, 1992. The Stockholm workshop met with great interest and many good contributions were received by the program committee. There were approximately 40 participants and 23 presentations were given - so many indeed that one might characterize the workshop as a working conference - and there were many discussions focusing on the presentations. The presentations dealt with a range of topics, including the clarification of ideas about the different concepts in multimedia, object-oriented methods for multimedia, multimedia from psychological perspectives, synchronization problems in multimedia, cooperative work using multimedia, and building multimedia interfaces. The presentations were the focus for numerous discussions. There was also a small exhibition of four different multimedia systems, representing the spectrum from research prototypes to commercial products.
