Extending the Lexicon
MLR – Meta-Level Lexical Rules (lexical entries)
DLR – Description-Level Level Rules (word objects)
Extending the Lexicon with MLR
R = {r1,…rn} (binary relations)
B = {β1… β n} (base lexical entries)
L: (full set of lexical entries)
B<L
for all λ in L and r in R such that r(λ,φ) in L
Extending the Lexicon with DLR
Binary relations between word objects
Integration of lexical rules at the same level as the other grammatical constraints
