Sampling algorithms for PCFGs

PCFG parser

echo 'I was given a million dollars .' | python parse.py examples/wsj00 --grammarfmt discodop --unkmodel stfd6 -v --samples 100 --intersection nederhof --start TOP --log > nederhof.mc

Or

echo 'I was given a million dollars .' | python parse.py examples/wsj00 --grammarfmt discodop --unkmodel stfd6 -v --samples 100 --intersection earley --start TOP --log > examples/earley.mc

ITG parser

echo '1 2 3 4' | python itg-parse.py examples/itg

For small examples, we can list the permutations

echo '1 2 3 4' | python itg-parse.py examples/itg --show-permutations

Binarizable permutations

echo '1 2 3 4' | python binarizable.py
