    Abstract
    Ausgehend vom probabilistischen Relevanzbegriff werden die wichtigsten Ansätze der probabilistischen Indexierungsstrategien (einschließlich der nutztheoretischen Indexierung) aufgezeigt und mit dem statistischen Indexierungsmodell von Harter verglichen. Das probabilistische Retrievalmodell, das auf der Termunabhängigkeitsannahme basiert, wird detailliert erklärt und in Kontrast zum Termunabhängigkeitsmodell gestellt. Dabei wird auf die Probleme der Bestimmung der in den o.g. Strategien vorgeschlagenen Termgewichte hingewiesen. Zum Schluß wird noch auf die Beziehung der behandelten probabilistischen Modelle kurz eingegangen

    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
    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
