    Abstract
    Vorsatz zum Sinn von Normdateien: "Die sachgerechte Nutzung von Normdateien erfordert eine ausgeklügelte Datenbankstruktur, über die sich Bibliothekare und Informatiker offensichtlich erst noch verständigen müssen"; Hauptsatz zur Redundanz von P,T,G,C,K,Z,F - verbale Sacherschließung als Funktion: "Außer den Sachschlagwörtern können alle anderen Schlagwortkategorien der RSWK/SWD 'eingespart', auf die Einrichtung eigener Schlagwortkettenfelder in den Titelaufnahmen kann verzichtet werden: Nachsatz zur 'Kombinatorik': "An die Stelle von Schlagwortketten würden Chiffren für Verknüpfungskombinationen ('Kombinationsmuster') treten, die auch im Sinne von Steuerungsinstrumenten zu nutzen wären"

    Abstract
    Although subject hierarchies are widely used to index document collections, few tools leverage their structure to facilitate collection browsing. This is mostly due to the complexity of such structures that include thousands of nodes. This paper proposes a new approach to simplify subject hierarchies based on the distribution of documents among the nodes. A random walk algorithm simulates the route of a user within the hierarchy, under the assumption that the user is attracted by the most populated nodes. Poorly visited nodes can be identified and eliminated, leaving a structure containing only the nodes that best represent the content of the collection. Experiments on a collection indexed using the Library of Congress Subject Headings (LCSH) show that, as compared to the state-of-the-art simplification method, the random walk-based approach gives access to a larger part of the collection for the same structure size, and offers more flexibility to customize the complexity of thestructure.

    Abstract
    The Library of Congress Subject Headings (LCSH) is a subject structure used to index large collections throughout the world. Browsing a collection through LCSH is difficult using current on-line tools in part because they are inadequately integrated with information collections. Users of these LCSH browsing tools are expected to find a promising LCSH string before using it to search for the information itself; many users do not have the patience for such a two-step process. This article proposes a method to fully integrate a specific collection in its subset of the LCSH hierarchy in order to facilitate LCSH browsing as well as information retrieval. Techniques are described to match LCSH strings assigned to the collection with an established string from the authority records, and build their specific LCSH hierarchy. The resulting subset of LCSH structure is described in terms of its size and broader/narrower term statistics, and implications for browsing and information retrieval are discussed. The results of this research have implications for institutions wishing to further capitalize on existing LCSH organization investments for the purpose of subject browsing and information retrieval.
