Definition: Concept Lattice

  • The concepts of a given context are naturally ordered by a subconcept-superconcept relation:
    • (A 1 , B1 ) ≤ (A 2 ,B 2 ) : A 1 ⊆A 2 (⇔ B 2 ⊆B 1 )

  • The ordered set of all formal concepts in (G,M,I) is denoted by Β(G,M,I) and is called concept lattice (Begriffsverband)

  • A concept lattice consists of the set of concepts of a formal context and the subconcept-superconcept relation between the concepts
