- Abstract
- Electronic texts offer new ways to store, retrieve, update, and cross-link information. Hypermedia documents require new levels of organization and strict discipline from authors, editors, and managers. This book provides a step-by step guide to all aspects of hypermedia development, from strategic decision-making to editing formats and production methods

- Abstract
- Der Beitrag versucht eine Bestimmung der Charakteristika von Hypertext- und Expertensystemen, unter dem Aspekt ihrer wechselseitigen funktionellen Ergänzung. Er stellt an ausgewählten kommerziellen Systemen unterschiedliche Konzepte der Kopplung und Integration vor. Als Desiderat sowohl für die Entwicklung wie die Anwendung der Verbindung beider Systemtypen erweist sich ein übergreifendes datenmodell. Hier wird gegenüber den vorherrschenden an der VonNeumann-Programmierung orientierten Ansätzen für ein relationales Konzept plädiert

- Abstract
- Ein Grundproblem der rechnergestützten Erstellung, Bearbeitung und Archivierung von Dokumenten ist die unzureichende Wiedergabe von Inhalt und Struktur durch die heute verbreiteten Dokumentformate und Seitenbeschreibungssprachen. Die Standard Generalized Markup Language löst dieses Problem druch die präzise und flexible Beschreibung der Struktur von Dokumenten. SGML ermöglicht dadurch die vielseitige Nutzung der in Dokumenten enthaltenen Information für elektronische Publikationen, Hypertext-Systeme, Online-Dokumente, aber auch für die klassischen Formen der Publikation in Buch, Zeitschrift und Loseblattwerk. Darüber hinaus dient der ISO-Standard SGML als Austauschformat in heterogenen DV-Umgebungen. Das Buch vermittelt sowohl die für die Entscheidungsträger notwendigen Informationen als auch das Basiswissen für den Entwickler. Es gibt einen praxisorientierten Einstieg in Vorteile und Anwendungsgebiete von SGML, behandelt anhand vieler Beispiele die verschiedenen Bestandteile von Dokument-Typ-Definitionen und gibt einen Überblick über die verfügbare SGML-Software. Für Anwender von SGML und Entwickler von SGML-Anwendungen, DV-Fachleute in Verlagen, technische Dokumentare und allgemein an Dokumentverarbeitung Interessierte.

- Abstract
- This article examines searcher behavior and affective response to a hypertext-based bibliographic information retrieval system called HyperLynx for searchers with different search skills and backgrounds. Search times and number of nodes visited were recorded for five specified search queries, and views of the system were recorded for each searcher. No significant differences were found in search times or user satisfaction with the system, indicating that a hypertext-based approach to bibliographic retrieval could be appropriate for a variety of searcher experience levels

- Abstract
- People who work in a research, academic or business environemtn often have personal information collections which are large enough to need retrieval aids. A major difference between personal information retrieval and standard information retrieval is that the items to be retrieved are often associated with events in the searcher's life and ca be retrieved by their relationship of other events as well as by content. Describes the background to evenet based retrieval and describes a prototype graphical event based retrieval system, developed at Kent University, UK, employing the hive event browser

- Abstract
- Describes SIFT (Search in Free Text) an information retrieval system originally developed for administering governmental documents in Norway but which is now being applied alsewhere. SIFT handles structured information well. A library system, SIFT-BIBL, is now available. SIFT's retrieval engine and search facilities are powerful. Its user interface is limited but being imporved. An application programmer interface has been released which will allow programmers to develop their own interface. A Windows-based- client-server version is now being beta tested

- Abstract
- This article is about the mental coding processes involved in the flow of 'information' when the user is interacting with an 'enabling' information retrieval system. An 'enabling' IR system is designed to stimulate the user's grasping towards a higher understanding of the information need / problem / task that brought the user to the IR system. C. Shannon's (1949/1959) model of the flow of information and K.R. Popper's (1975) 3 worlds concept are used to diagram the flow of information between the user and system when the user receives a stimulating massage, with particluar emphasis on the decoding and encoding operations involved as the user processes the message. The key difference between the model of information flow proposed here and the linear transmission, receiver-oriented model now in use is that we assume that users of a truly interactive, 'enabling' IR system are primarily message senders, not passive receivers of the message, because they must create a new message back to the system, absed on a reconceptualization of their information need, while they are 'online' interacting with the system

- Abstract
- Proceedings of the 5th TREC-confrerence held in Gaithersburgh, Maryland, Nov 20-22, 1996. Aim of the conference was discussion on retrieval techniques for large test collections. Different research groups used different techniques, such as automated thesauri, term weighting, natural language techniques, relevance feedback and advanced pattern matching, for information retrieval from the same large database. This procedure makes it possible to compare the results. The proceedings include papers, tables of the system results, and brief system descriptions including timing and storage information

- Abstract
- Reports on the design of a GUI for the Okapi 'best match' retrieval system developed at the Centre for Interactive Systems Research, City University, UK, for online library catalogues. The X-Windows interface includes an interactive query expansion (IQE) facilty which involves the user in the selection of query terms to reformulate a search. Presents the design rationale, based on a game board metaphor, and describes the features of each of the stages of the search interaction. Reports on the early operational field trial and discusses relevant evaluation issues and objectives

- Abstract
- This article investigates the potentialities of using empirical variables and their associated statistical relationships in document representation and retrieval. To this end, a newly devised empirical fact retrieval system (EFRS) was evaluated in comparison to a simulated traditional retrieval system (TRS) involving a set of predetermined empirical queries. Results indicate that the EFRS generally outperformed the TRS in terms of precision, search effort, and measures of user satisfaction. Possible advantages of the EFRS, as well as the necessity of establishing an efficient methos for extracting empirical facts, are discussed

- Abstract
- Describes the design and implementation of a system for computer generation of linked HTML documents to support information retrieval and hypertext applications on the WWW. The system does not require text query input, nor any client or host processing other than hypertext linkage. The goal is to construct a fully automatic system in which original text documents are read and processed by a computer program that generates HTML files, which can be used immediately by Web browsers to search and retrieve the original documents. A user with a large collection of information: for instance, newspaper articles; can feed these documents to this program and produce directly the necessary files to establish WWW home page and related pages, to support interactive retrieval and distribution of the original documents

- Abstract
- Discusses the complex nature of urban, regional and local documents management, the decision making process of an in house classification system, and problems of converting a manual card cataloguing system to an computerized information retrieval system at Florida International University Library. The principles of this in house classification system can be used for any specialized collection

- Abstract
- Describes 2 research projects aimed at studying the parallel issues of image and video indexing, information retrieval and manipulation: VisualSEEK, a content based image query system and a Java based WWW application supporting localised colour and spatial similarity retrieval; and CVEPS (Compressed Video Editing and Parsing System) which supports video manipulation with indexing support of individual frames from VisualSEEK and a hierarchical new video browsing and indexing system. In both media forms, these systems address the problem of heterogeneous unconstrained collections
