pycdec is a Python interface to cdec
## Installation
Build and install pycdec:
python setup.py install
Alternatively, run `python setup.py build_ext --inplace` and add the `python/` directory to your `PYTHONPATH`.
## Grammar extractor
Compile a parallel corpus and a word alignment into a suffix array representation:
python -m cdec.sa.compile -f f.txt -e e.txt -a a.txt -o output/ -c extract.ini
Or, if your parallel corpus is in a single-file format (with source and target sentences on a single line, separated by a triple pipe `|||`), use:
python -m cdec.sa.compile -b f-e.txt -a a.txt -o output/ -c extract.ini
Extract grammar rules from the compiled corpus:
cat input.txt | python -m cdec.sa.extract -c extract.ini -g grammars/ -z
This will create per-sentence grammar files in the `grammars` directory and output annotated input suitable for translation with cdec.
Extract rules in stream mode:
python -m cdec.sa.extract -c extract.ini -t -z
This will enable stdio interaction with the following types of lines:
Extract grammar:
context ||| sentence ||| grammar_file
Learn (online mode, specify context name):
context ||| sentence ||| reference ||| alignment
Drop (online mode, specify context name):
context ||| drop
## Library usage
A basic demo of pycdec's features is available in `examples/test.py`.
Other examples are given in [the paper](http://victor.chahuneau.fr/pub/pycdec/) describing pycdec.
More documentation will come as the API becomes stable.
