Abstract

Hypertext, eine neue Art der Informationsdarstellung, ist innerhalb weniger Jahre zu einem auf zahlreichen Fachkonferenzen diskutierten Thema im Umfeld von Informatik, Informationswissenschaft, K?nstlicher Intelligenz, Linguistik, Psychologie und Lerntheorie geworden. Die Faszination, die von diesem Medium auf Forschung, Entwicklung und Anwendung gleicherma~en ausgeht, beruht auf der prinzipiell nichtlinearen Organisation der Hypertexteinheiten und den benutzerfreundlichen Formen des ebenfalls nichtlinearen, flexiblen Zugriffs auf die Einheiten in einem Hypertextsystem. In dieser Einf?hrung in die Hypertextmethodik werden die wesentlichen Elemente von Hypertextsystemen, die Informationseinheiten und Verkn?pfungsarten sowie die hypertextspezifischen Navigationsformen, ausf?hrlich theoretisch und anschaulich am Beispiel existierender kommerzieller und experimenteller Hypertextsysteme behandelt. Besonderer Wert wird auf den Zusammenhang von Hypertext und Information Retrieval und die Einsatzm÷glichkeiten von Hypertext in Lernumgebungen gelegt. In theoretischer Hinsicht wird untersucht, ob sich Hypertextbenutzer mit Vorteil gegen?ber anderen Medien die Information erarbeiten k÷nnen, die sie aktuell in kritischen Situationen ben÷tigen, ob und wodurch also gegen?ber traditionellen linearen Formen ein ~informationeller Mehrwert~ erzielt wird. Au~erdem wird die M÷glichkeit diskutiert, mit Hilfe von Textanalyseverfahren und Techniken der Wissensrepr"sentation Hypertexte aus Texten automatisch aufzubauen. Das Buch enth"lt eine umfassende Bibliographie und im Anhang ein Glossar und eine strukturierte Beschreibung der wichtigsten gegenw"rtig erh"ltlichen oder in Entwicklung befindlichen Hypertextsysteme.
