Depfix is open-source, licenced under the GNU General Public License v2. Detailed instructions on installing and running Depfix can be found in the Depfix Manual (PDF, HTML); a very short version is presented here.
The TL;DR version of the installation manual is the following:
wget -O install.tgz http://goo.gl/FpIOuw tar -zxvf install.tgz cd install bash all.sh
Once installed, test if you have Depfix working by doing:
cd ~/treex/devel/depfix make test
This should run for several minutes, printing out various progress information, finally ending by a printout of the BLEU score and other scores.
To run Depfix on your own data, use a command such as the following:
make DATA_EN=english_source.txt DATA_CS=smt_translation.txt REFERENCE_CS=human_translation.txt
The input files must have one sentence per line and be in UTF-8 (there are some sample files in the data subdirectory).
When Depfix successfully finishes, it saves the post-edited translations in the output.txt in the experiment directory that it created.
