I'm a Computer Science student from France. This year, I did both an engineering degree (ENSIMAG) and a Master of C.S. spec. in Artificial Intelligence and Web. I am currently doing my Master's research internship at National Institute of Informatics in Tokyo on Inductive Logic Programming applied to biology systems.

Basic pruning

Needed files:

  • replace.py (in apertium-combine/scripts/)
  • split_prune.sh (in apertium-combine/scripts/)
  • pruning.cc (in apertium-combine/pruning/)
  • your lowercased corpus (see here)
python replace.py lowercase.en lowercase.cy

then use this "lowercase.rep.en" and "lowercase.rep.cy" for the following of the phrase-table building (see below, Workflow for training a LM)

sh split_prune.sh phrase-table

while having set the "exe" inside the script to the good path to your compiled pruning.cc (g++ -O3 apertium-combine/pruning/pruning.cc)
