Abstract

Seit 1985 wird das automatische Indexierungssystem AIR/PHYS in der Inputproduktion der Physik-Datenbank PHYS des Fachinformationszentrums Karlsruhe angewandt. Das AIR/PHYS-System teilt englischsprachigen Referatetexten Deskriptoren aus einem vorgeschriebenen Vokabular zu. In der vorliegenden Arbeit werden der zugrundeliegende fehlertolerierende Ansatz, der Aufbau des Systems und die wichtigsten Verfahren zur Entwicklung eines großen Indexierungswörterbuches beschrieben. Ferner werden Probleme der Anwendung und Weiterentwicklung des Systems behandelt

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.

Abstract

Ausgehend von theoretischen Indexierungsansätzen wird das klassische Vektorraum-Modell für automatische Indexierung (mit dem Trennschärfen-Modell) erläutert. Das Clustering in Information-Retrieval-Systemem wird als eine natürliche logische Folge aus diesem Modell aufgefaßt und in allen seinen Ausprägungen (d.h. als Dokumenten-, Term- oder Dokumenten- und Termklassifikation) behandelt. Anschließend werden die Suchstrategien in vorklassifizierten Dokumentenbeständen (Clustersuche) detailliert beschrieben. Zum Schluß wird noch die sinnvolle Anwendung der Clusteranalyse in Information-Retrieval-Systemen kurz diskutiert
