Abstract

The subject of this book is the relationship between people and interactive media. Written by one of the world's leading experts on this subject, this book explores how hypermedia, groupware, and networks change the way in which people, gropus and organizations work and interact. Its wide-ranging focus discusses the emergence of new technologies and demonstrates by considering real-life case studies the impact each has had on the way we view and interact with colleagues and information. With its emphasis on actual examples of usage, the author provides both practitioners and students with a fascinating glimpse of the future of these media and their applications.

Abstract

The disciplines of human-computer interaction, computer-supported collaborative work, information storage and retrieval, and artificial intelligence should complement one another in the new discipline of hypertext. This holistic view of hypertext focuses on links: links within a document (microtext), links among documents (macrotext), links among people (grouptext), and dynamic links (expertext). The principles and systems which are relevant to creating and accessing hypertext can be usefully presented under the heading of text, microtext, macrotext, grouptext and expertext. From text to expertext, people consistently use hierarchical structures, particularly hierarchical semantic nets, to organize information

Abstract

When document components are classified and then recombined during document re-use, a semantic net may serve as the classification language. A theory of analogical inheritance, applied to this semantic net, guides the reorganisation of document components. Authors index paragraphs from various sources with node-link-node triples from a semantic net and then use programs to transverse the semantic net and generate various outlines. The program examines node and link names in deciding which path to take. Describes how these techniques helped in the re-use: parts of an existing book to write a new one

Abstract

Maintaining a thesaurus is a time-consuming task which should go hand-in-hand with the indexing of information and should be supported by software. To connect different document databases their respective thesauri should be related. The most straightforward way to support to support this by computer is to map the terms of one thesaurus to those of another. Such a mapping creates one kind of metathesaurus. As citation systems are extended to include full-text online, a new thesaurus may be used to index individual paragraphs. To illustrate these principles several computer systems are described which help people maintain thesauri and metathesauri. Particular success has been had by the National Library of Medicine with its Medical Subject Headings and its Unified Medical Language System

Abstract

Attemps to elaborate the relationships among tasks, user types, and tools for hypertext. A computer system was built for automatically converting books into hypertext and one book converts into Emaccs-Info, Guide, HyperTies, and a variant of SuperBook, called MaxiBook. Compares the performance of 3 classes of users - expers, novices and trainees - with different tasks on these different delivery vehicles, the tasks involving one search question and one browse question

Abstract

The concepts of hypertext, multimedia and hypermedia are often confused, but can defined thus: hypertext is text with links, multimedia is synchronized media, and hypermedia is multimedia with links. Presents descriptions of systems for hypertext, multimedia and hypermedia. The computer storage and processing requirements for multimedia are orders of magnitudes greater than those for hypertext. Nevertheless, the hypertext model can be extended to deal with hypermedia by including multimedia synchronization capabilities. Information technology and its associated terminology should help people effectively compare experiences and thus have more influence on future developments

Abstract

Online textbooks can be connected to other sources of information to improve their educational value. We describe 2 case studies. One used in a medical textbook and connected to medical journal abstracts via a thesaurus. The textbook, journal abstracts, and thesaurus were stored on a CD-ROM. The other case study shows a textbook on the WWW that is connected to various other sources of information. About half the book references are to web sites, and the textbook is part of an online course that is connected to an online catalog and other courses. Such linkages among information spaces should help students navigate the information relevant to their studies
