We relate the problem of finding the best application of a Synchronous ContextFree Grammar (SCFG) rule during parsing to a Markov Random Field. This representation allows us to use the theory of expander graphs to show that the complexity of SCFG parsing of an input sentence of length N is Ω(N cn), for a grammar with maximum rule length n and some constant c. This improves on the previous best ...
