    Abstract
    Für die automatische Erschließung natürlich-sprachlicher Dokumente in einem Informationssystem wurde ein Verfahren zur automatischen thematischen hierarchischen Klassifikation der Texte entwickelt. Die dabei gewonnene Ordnungsstruktur (Begriffsnetz) wird beim Retrieval als Recherchehilfe engeboten. Die Klassifikation erfolgt in vier Stufen: Textindexierung, Prioritätsklassenbildung, Verknüpfung der begriffe und Vernetzung der Prioritätsklassen miteinander. Die so entstandenen Wichtigkeitsstufen sind die Hierarchieebenen der Klassifikation. Die während des Clusteringverfahrens erzeugten Begriffs- und Dokumenten-Gruppierungen bilden die Knoten des Klassifikationsnetzes. Die Verknüpfung zwischen den Knoten benachbarter Prioritätsklassen repräsentieren die Netzwege in diesem Netz. Die Abbildung der Suchfrage auf dieses Begriffsnetz wird zur Relevanzbeurteilung der wiedergewonnenen Texte benutzt
