    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
    Es wird zunächst ein "ideales Information-Retrieval-System" beschrieben und diskutiert. Als Kernproblem für -selbst bescheidene - Entwicklungen in die dadurch aufgezeigte Richtung wird das "Verstehen" von Texten durch den Computer angesehen, wobei je nach der Aufgabenstellung einer Systemkomponente stets nur ein partielles Verstehen erforderlich ist. Ein relativ einfaches, aber keineswegs triviales Beispiel dieser Art ist die automatische Indexierung von Referatetexten bei vorgegebenen Deskriptorensystem. Von diesem Problem werden Ansätze, Ergebnisse und Erfahrungen mitgeteilt. Darauf aufbauend werden weitere Forschungsrichtungen und Entwicklungsmöglichkeiten mitgeteilt

    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

    Abstract
    Über eine Schnittstelle zwischen Programmen zur automatischen Indexierung (PRIMUS-IDX) und zur maschinellen Thesaurusverwaltung (INDEX) sollen große Textmengen schnell, kostengünstig und konsistent erschlossen und verbesserte Recherchemöglichkeiten geschaffen werden. Zielvorstellung ist ein Verfahren, das auf PCs ablauffähig ist und speziell deutschsprachige Texte bearbeiten kann

    Abstract
    A study was done to test the effectiveness of retrieval using title word searching. It was based on actual search profiles used in the Mechanized Information Center at Ohio State University, in order ro replicate as closely as possible actual searching conditions. Fewer than 50% of the relevant titles were retrieved by keywords in titles. The low rate of retrieval can be attributes to three sources: titles themselves, user and information specialist ignorance of the subject vocabulary in use, and to general language problems. Across fields it was found that the social sciences had the best retrieval rate, with science having the next best, and arts and humanities the lowest. Ways to enhance and supplement keyword in title searching on the computer and in printed indexes are discussed.

    Abstract
    Geisteswissenschaftliche Fachinformation erfordert eine enge Kooperation zwischen Literaturnachweis- und Terminologieinformationssystemen. Eine geeignete Dokumentationsmethode für die Auswertung geisteswissen- schaftlicher Literatur ist die Textwortwethode. Dem originalsprachig aufgenommenen Begriffsrepertoire ist ein einheitssprachiger Zugriff beizuordnen, der einerseits ein vollständiges und genaues Retrieval garantiert und andererseits den Aufbau fachspezifischer Wörterbücher vorantreibt
