Representation of classifications using apposition in Formal Concept Analysis: an application to cladistics as an example

Abstract

This paper proposes an FCA technique for representing classifications, which is a use of the apposition with the nominal scale on the objects. It removes the hierarchical order between the object concepts, while it preserves the hierarchical orders between the attribute concepts and between the object concepts and the attribute concepts. As an example, it is applied to cladistic analysis.
