... A propositional variable (lowercase letters p, q, r) is a proposition. These variables model true/false statements. The negation of a proposition P, written ¬ P, is a proposition. The conjunction (and) of two propositions, written P ∧ Q, is a proposition. The disjunction (or) of two propositions, wr ...

Computing the least common subsumer
... These applications (and how formal concept analysis can be employed in this context) are described in more detail in [3]. The least common subsumer (lcs) in DLs with existential restrictions was investigated in [5]. In particular, it was shown there that the lcs in the small DL EL (which allows conj ...

These two classes of algebraic structures are tightly related via the equivalence Γ. This connection is exploited in the third section of the chapter. The content of Chapter 2, a ...
