chisel

chisel is an SMT decoder based on sampling. It implements a number of sampling strategies and different decision rules for SMT. It works with phrase-based and hierarchical phrase-based models. Lots of its features are not yet availabile in the repository, but that won't last long.

Requirements

I have added a few features to some of the dependencies below, these changes might not yet have made their way upstream, so you might need to download them from my forks.

• kenlm
• cdec
• jieba (for Chinese segmentation)
• numpy
• tabulate (for nice output)

Installing

I recommend you use virtualenv

virtualenv chiselenv
source chiselenv/bin/activate

• kenlm

    git clone https://github.com/wilkeraziz/kenlm.git 
    python setup.py install
  

• cdec

    git clone https://github.com/wilkeraziz/cdec.git 
    autoreconf -ifv
    ./configure
    make
    cd python
    python setup.py install
  

• jieba

    pip install jieba
  

• numpy

    pip install numpy
  

• chisel

    python setup.py install
