Abstract

Die automatische Indexierung von Dokumenten für das Information Retrieval, d. h. die automatische Charakterisierung von Dokumentinhalten mittels Deskriptoren (Schlagwörtern) ist bereits seit über 25 Jahren ein Gebiet theoretischer und experimenteller Forschung. Dagegen wurde erst im Oktober 1985 mit der Anwendung der automatischen Indexierung in der Inputproduktion für ein großes Retrievalsystem begonnen. Es handelt sich um die Indexierung englischer Referatetexte für die Physik-Datenbasis des Informationszentrums Energie, Physik, Mathematik GmbH in Karlsruhe. In dem vorliegenden Buch beschreiben Mitarbeiter der Technischen Hochschule Darmstadt ihre Forschungs- und Entwicklungsarbeiten, die zu dieser Pilotanwendung geführt haben.
