Combining Predicate and Functor Relevance

Intuition

• Relevance measured by predicates, functors, or both
• Combining them when measured seperately

Definition

• Let Rp be the measure by predicates, Rf the measure by functors
• The combined normalized measure by Euclidean distance is

    (Rp2 + Rf2)
  ( ----------- )0.5
         2   

• The combined normalized measure by probability is

  1 - ((1 - Rp) * (1 - Rf))2
