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`. To re-build pycdec from the cython source, modify setup.py in the following ways: * Add this input statement: from Cython.Build import cythonize * Change the source file from cdec/\_cdec.cpp to cdec/\_cdec.pyx * Add language='c++' as a property to ext\_modules (e.g. right after extra\_link\_args) * In the final setup block, change ext\_modules=ext\_modules to ext\_modules=cythonize(ext\_modules) Then just build and install normally, as described above. To rebuild cdec/\_cdec.cpp, run: cython --cplus \_cdec.pyx ## 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. --- pycdec was contributed by [Victor Chahuneau](http://victor.chahuneau.fr)
