Abstract

Beim Vergleich von Klassifikationen mit Frame-Wissensbasen für Expertensysteme zeigen sich einige elementare Gemeinsamkeiten: Beide haben das Ziel einer geordneten Darstellung von Wissen. Beide bilden dazu Klassen und weisen hierarchische Beziehungen zwischen diesen Klassen auf. Anahnd der Wissensrepräsentationssprache FRL (Frame Representation Language) wird untersucht, inwieweit beide Systeme sich in das jeweils andere übertragen lassen. Die FRL speichert Wissen in einer speziellen Datenstruktur, den Frames, die aus einem Framenamen, der den jeweiligen Begriff bezeichnet, und Slots, die die Eigenschaften des Begriffs enthalten, bestehen. Eine effektive Speicherung des Wissens wird dadurch erreicht, daß die Frames in einer polyhierarchischen Struktur geordnet sind und in generischer Relation zueinander stehen müssen. Über die generische Relation lassen sich die Eigenschaften höherer Begriffe auf ihre Subklassen vererben. Es werden die Ergebnisse eines Versuchs dargestellt, Elemente bestehender Universalklassifikationen (DK, BC2) in die FRL zu übertragen
