A fast, memory efficient Python module to remove duplicates from parallel text corpora.
It's useful for cleaning up datasets that contain duplicate entries for training language models.
pip install removedupfrom removedup import rdup
src, tgt, removed = rdup("source.txt", "target.txt")
print(src, tgt, removed)
# source.txt.dedup
# target.txt.dedup
# <num lines removed>Source and target must have the same number of lines. No validation checks are made.
Duplication checks are only made on the source content. If you want to check for duplicates on the target, simply switch the order of the parameters.
git clone https://github.com/LibreTranslate/RemoveDup
cd RemoveDup
python setup.py buildYou can also use removedup as a standalone Windows, macOS or Linux application (but you currently need to build from source, we don't provide binaries).
mkdir build
cd build && cmake .. && make -j4
./rdup source.txt target.txt
