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

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

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

Draws together research from a variety of disciplines to consider why and how information technology is qualitatively different from older technologies of information, and why this promotes changes at both the individual and the social level. Concludes from this analysis that there are 2 diverging directions for organizational and societal development: towards technocracy or towards the learning organization and the learning society. In both there will be roles that could be filled by librarians, but the learning organization's network structure would offer many more opportunities for active intermediary roles, and it is in accord with the social ethic of the library profession. In a technocracy, the librarian might assume the high status role of 'knowledge manager' but be out of touch with the ultimate users of information. Considers the pursuit of professional status by librarians as not being the best way to ensure the continuation of the 'social ethic' according to which librarians are educated. A new model of professionalism is needed along the lines suggested by D.A. Schon for the 'reflective practioner', in which knowledge and expertise are collaboratively developed in the interchange between the professional and the client

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

The Many Using and Creating Hypermedia (MUCH) systems is based on the Dexter model and treats the storage layer as a semantic net. The MUCH system provides a numer of recommended link types for representing application domain concepts, such as thesauri, documents and annotations. users of the system are expected to use those link types in the course of authoring meaningful hypermedia. based on the logs of usage of the MUCH system over 2 years by over 200 people, contrary to the designers' expectations, users did not exploit the ability to type semantic links. Typically authors used the default link type regardless of their semantic intentions. When a link type other than the default type was chosen, that choice was often inconsistent with the way another user would able a similar link. The system has proven to be useful for authoring conventional documents. Authors, however, were not practically able to produce hypertext documents. Based on these experiences a new system, RICH (Reusable Intelligent Collaborative Hypermedia), has been designed and built which emphasizes rules for typing links and maintaining the integrity of the semantic net

Abstract

An indexing language is made more accessible to searchers and indexers by the presence of entry terms or near-synonyms. This paper first presents an evaluation of existing entry terms and then presents and tests a strategy for creating entry terms. The key tools in the evaluation of the entry terms are documents already indexed into the Medical Subject Headings (MeSH) and an automatic indexer ...

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

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

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

Navigation problems in a hypertext migth be reduced, if mutiple, coherent views of the hypertext were available. Document outlines help readers appreciate the structure and meaning of the document. Proposes measures of syntactic and lexical balance in an outline and show in a sample of documents the degree to which these balances occur. Based on balance in an outline, a method for semi-automatically generating an alternative outline is applied to one textbook. The textbook with both its original and its alternative outline is availbale in hypertext, and subjects who were asked to evaluate this hypertext noted that the alternative outline would help readers compare concepts in the textbook

Abstract

Investigates information-seeking tasks and associated cognitve issues in the context of interacting with an evolving collaborative hypertext. Fishexe view browsers were used to facilitate exploring in a large information space. The fishexe view browser was extended to incorporate word frequencies. The effects of the fisheye view browser and the changing document were tested with 2x2 factorial experiment. Multivariate tests founs a significant interaction between the 2 factors and a significant main effect of the fisheye view browser. The users who had access to the word frequency information performed their tasks more effectively than the users without access to word frequencies. This work implies that several aspects of an evolving hypertext might als be useful incorporated in an associated fishexe view browser

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.
