Building Sub-Knowledge Bases Using Concept Lattices

J. J. Sarbo *

Computing Science Institute, University of Nijmegen, Toernooiveld 1, 6525 ED Nijmegen, The Netherlands

A theory of concept (Galois) lattices was first introduced by Wille. An extension of his work to simple structures called concept sublattices has also been published. This paper shows that concept sublattices can be applied to (i) determining subsumption of specifications and (ii) decomposing specifications in terms of others. I show that the latter application of the theory may provide us with new conceptualizations of a specification.

Received May 21, 1996. revised June 9, 1997.
