- Abstract
- Some people argure that hypertext is easy to write, is hard to create by converting existing text into hypertext, and has a massive market. This paper argures the contrary. First, Hypertext is hard to write. Second, automatically converting a text into hypertext is, to a first approximation, easy. Third, successful marketing of hypertext depends on having a large volume of material that is also available in paper form

- 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

- 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
- Existing structures should be exploited as best as possible in the course of document reuse. Reuse may take multiple forms: rearranging a single document so as to provide different views of the same information, copying a portion of a single document to as to provide a portion of a new document, and combining portions of existing documents to constitute a new document. Algortihms are presented to do such reuse, examples are provided. For significant reuse the information in existing documents need to be abstracted so as to highlight the conceptual pattern

- 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
- Presents a study on hypertext examining the cognitive styles and spatial ability of users; the complexity of tasks; and the strucutre of information organization and the visualization of the structure. Future work on hypertext usability should emphasize task taxonomies along with longitudinal and ethnographic studies for a deep understanding of the interactions between users and hypertext

- Abstract
- A thesaurus may be viewed as a graph, and document retrieval algorithms can exploit this graph when both the documents and the query are represented by thesaurus terms. These retrieval algorithms measure the distance between the query and documents by using the path lengths in the graph. Previous work witj such strategies has shown that the hierarchical relations in the thesaurus are useful but the non-hierarchical are not. This paper shows that when the query explicitly mentions a particular non-hierarchical relation, the retrieval algorithm benefits from the presence of such relations in the thesaurus. Our algorithms were applied to the Excerpta Medica bibliographic citation database whose citations are indexed with terms from the EMTREE thesaurus. We also created an enriched EMTREE by systematically adding non-hierarchical relations from a medical knowledge base. Our algorithms used at one time EMTREE and, at another time, the enriched EMTREE in the course of ranking documents from Excerpta Medica against queries. When, and only when, the query specifically mentioned a particular non-hierarchical relation type, did EMTREE enriched with that relation type lead to a ranking that better corresponded to an expert's ranking

- 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
