This corresponds to the multiset version of intersection.
for all τ ∈ R * R * and w ∈ V: It is clear that the effectiveness of INT increases as the size of C grows, and that it would particularly benefit from distributional smoothing (Dagan, Pereira, and Lee 1994), which can be used to improve plausible co-occurrence coverage by inferring co-occurrences in the APT for a lexeme w based on the co-occurrences in the APTs of distributionally similar lexemes.
