Abstract

Für die automatische Indexierung mit einem vorgegebenen Deskriptorensystem wird ein Wörterbuch benötigt, das möglichst viele Fachausdrücke des Anwendungsgebietes durch Relationen mit Deskriptoren verbindet. Werden die in einem solchen Indexierungswörterbuch erfaßten Relationen aus der Verarbeitung von Texten gewonnen, so ergibt sich eine Beziehung zwischen der Anzahl der Texte und der Größe und Leistungsfähigkeit des Wörterbuches. Die beschreibung derartiger Beziehungen ist besonders vor Beginn der Entwicklung eines automatischen Indexierungssystems von großem Interesse. H. Hüther hat sich in mehreren Arbeiten mit diesem Problem beschäftigt und verschiedene Schätzverfahren theoretische hergeleitet. Für eines der von ihm vorgeschlagenen Schätzverfahren zur Abschätzung der Größe eines Indexierungswörterbuches in Abhängigkeit von der Anzahl der zugrundeliegenden Texte werden im vorliegenden beitrag die Leistungsfähigkeit und die Anwendbarkeit untersucht
