Abstract: In diesem Beitrag geht es um die Übertragung komplexer Hypertextmodelle, die dynamisches Verhalten von Dokumenten ermöglichen, in das WWW. Ein Ansatz, um dieses Ziel zu erreichen, wird anhand des Hypertextmodells des Konstanzer Hypertextsystems (KHS) entwickelt und beispielhaft erläutert. Zunächst wird eine Einführung in die Problemstellung gegeben. Es folgt eine kurze Darstellung des Modells des KHS. Die Abbildung struktureller und dynamischer Aspekte dieses Modells in das WWW wird dann in den nächsten 2 Kapiteln diskutiert

Abstract

Fortschrittliche Informationssysteme stellen ihren Benutzern 2 wichtige Suchmethoden zur Verfügung: die gezielte (Volltext-) Suche und das Navigieren im Objektbestand mit Hilfe von Hypertext-Links. Der Grund, warum diese beiden Konzepte aber auf breiter Basis noch nicht in jedem Informationssystem Anwendung gefunden haben, ist darin zu sehen, daß der manuelle Aufbau von umfassenden Hypertext-Strukturen auf der einen Seite und von großen Thesauri, die den Erfolg von Volltextsuchen wesentlich steigern, auf der anderen Seite bislang enormen Aufwand und damit hohe Kosten verursachte. Langfristig werden Informationssysteme aber nur dann große Akzeptanz bei der Benutzerschaft erzielen, wenn sie ihre Benutzer mit diesen beiden Techniken unterstützen und wenn sie dynamisch neuen Informationsbedürfnissen anpassen können, also lernfähig sind. Für den einzelnen Benutzer ergibt sich daraus der wesentliche Vorteil, daß er von den Recherche-Erfahrungen anderer Benutzer profitieren kann. In diesem Papier stellen wir eine Lernkomponente vor, die für das Hypertextsystem 'HyperMan' an der TU München entwickelt und implementiert wurde. Wir zeigen beispielhaft, wie Volltext-Suchanfragen der HyperMan-Benutzer von der Lernkomponente untersucht werden, um Thesauruseinträge zu gewinnen. Bei der Entwicklung dieser Lerntechniken zum (automatischen) Thesaurusaufbau konnte auf Erfahrungen mit dem lernfähigen Information Retrieval System 'Tegen' zurückgegriffen werden. In dem HyperMan System werden aber nicht nur Beziehungen (Relationen) zwischen Begriffen erlernt, sondern auch zwischen Textstücken. Wir gehen daher auch darauf ein, wie aufgrund einer Analyse des Benutzerverhaltens sowohl neue Hypertext-Links erlernt als auch vorhandene Links, die zuvor von HyperMans Generierungskomponente automatisch erzeugt wurden, modifiziert werden

Abstract: Das System HYPERQUERY ist ein Informationssystem, das Benutzern den Zugriff auf stark vernetzte multimediale Informationen erleichtern soll. Hierzu wurde ein Hypertext- bzw. Hypermediasystem um eine Anfragekomponente erweitert, die den gezielten Einstieg in eine objektorientierte Datenbasis erleichtert. Das System soll insbesondere Gelegenheitsbenutzern ermöglichen, Reiseinformationen abzurufen. Der Benutzerschnittstelle fällt dabei eine wichtige Rolle zu. Die Implementierungen zweier unterschiedlicher graphischer Benutzeroberflächen der Anfragekomponente werden vorgestellt und diskutiert

Abstract: Die Komplexität des Entwurfs von Hypermedia-Systemen ist vergleichbar mit der Komplexität des Entwurfs von Expertensystemen, verlangt also nach einer methodischen Unterstützung im Entwurfsprozeß. Von dieser Motivation ausgehend, wird im vorliegenden Beitrag zunächst eine Analyse bestehender Dokumentenmodellierungsansätze durchgeführt, dann ein Ansatz zur formalen Beschreibung von Hypertext-Strukturen vorgestellt und schließlich mit dem Spatial-Satellite-Modell ein Beschreibungsansatz für Hypermedia-Strukturen präsentiert. Ausgehend von diesem Modell wird eine Entwurfsmethodik für Hypermedia-Systeme entwickelt, die als Ausgangspunkt für die Entwicklung eines Verständnisses für die Notwendigkeit eines 'Hypermedia-Engineering' bilden

Abstract: Wer digitale Bücher und Nachschlagewerke benutzt, anstatt gebundene Schmöker zu wälzen, der informiere sich schneller, umfassender und kreativer. So oder ähnlich werben Verlage und Buchhandlungen für ihre jüngsten elektronischen Publikationen. Obwohl dem Multimedia-Markt enorme Wachstumsraten prognostoziert und Hypermedia-Autoren immer gefragter werden, liegen Lust und Frust, Sinn und Unsinn zur Zeit noch eng beieinander. Wir stellen Strategien und Werkzeuge für ambitionierte Autoren vor und geben einen Einblick in den großen Markt der Applikationen

Abstract

Hypertext technology is appearing in mainstream commercial electronic data products including McGraw-Hill's CD-ROM version of their Encyclopedia of Science and Technology and the Facts on File News Digest 12-year cumulation. Provides a background to the development of hypertext. presents criticisms of hypertext and examples of its acceptance. Explores how hypertext translations of significant reference and information sources will penetrate the market. Discusses how hypertext could implement traditional information retrieval and control devices, the performance of people using hypertext and the absence of librarians in hypertext research and development

Abstract

The 2 general functions usually associated with hypertext environments are the retrieval of information, of which browsing is the most common method and the creation and linking of information, or authoring. Describes the results of the Hypertext Design Survey conducted at Indiana Univ. in order to gather information on 5 different features and issues of hypertext: the relative importance of browsing and authoring; the most important hypertext features; the most important user capabilities of hypertext; predictions of future hypertext users; and the most important impediments to hypertext use

Abstract

Offers an introduction to hypertext for librarians. Defines hypertext. Discusses the advantages of hypertext according to the creation and tracing of references; flexibility of nodes and links; cognition augmentation and collaborative work. Examines hypertext disadvantages and problems by considering its static nature; conceptual fragmentation; disorientation; cognitive overhead; presentation rhetoric; cost and intellectual security. Discusses library applications of hypertext covering information retrieval; online databases; citation indexing; OPACs and electronic books. Considers expert systems with hypertext features and hypertext with artificial intelligence
