Abstract

Ausgeführt wird, wie Begriffsverbände als Ablaufschemata zur Gegenstandsbestimmung genutzt werden können. Im Gegensatz zur Baumabfrage gestattet die beschriebene Methode dem Benutzer ein Höchstmaß an Freiheit und Transparenz. Demonstriert wird die Methode an der Bestimmung des Symmetrieprinzips von Flächenmustern

Abstract

A lattice theoretical description of concept hierarchies is developed using for attributes the terms "given", "negated", "open" and "impossible" as the truth-values of a four-valued logic. Similar to the theory of B. Ganter and R. Wille so does this framework permit a precise representation of the usual interdependences in a field of related concepts - such as superconcepts, subconcept, contrary concepts etc. -, whenever the concepts under consideration can be sufficiently described by the presence or absence of certain attributes ...
