we propose an

strategy, which pro-
duces grammars that parse almost as well as
grammars ... a directly in-
duced grammar parses test sentences with 66%
accuracy, whereas an adapted grammar parses
with 91% accuracy, which is only 2% lower than

Abstract
Generalized Multitext Grammar (GMTG) is a syn-
chronous grammar formalism that is weakly equiv-
alent to Linear Context-Free Rewriting ... component grammar of a GMTG retains
its generative power, and proposes a generalization
of Chomsky Normal Form, which is necessary for
synchronous CKY-style parsing.
