    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
    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
    Im Beitrag wird zunächst eine terminologische Klärung und Gliederung für drei Indexierungsmethoden und weitere Begriffe, die Konsistenzprobleme bei intellektueller Indexierung betreffen, unternommen. Zur automatichen Indexierung werden Extraktionsmethoden erläutert und zur Automatischen Klassifikation (Clustering) und Indexierung zwei Anwendungen vorgestellt. Eine enge Kooperation zwischen den Befürwortern der intellektuellen und den Entwicklern von automatischen Indexierungsverfahren wird empfohlen
