Python API/Library for Apertium[edit]

For this project, I coded swig wrappers to be used in the Apertium Python.

Mentors[edit]

Sushain Cherivirala, Shoutout to various aperitum members that helped throughout the project Tino Didriksen, Kevin Brubeck Unhammer, Francis Tyers,

Documentation[edit]

The Documentation in form of markdown for Apertium Python is available at README and on Read The Docs


Work Done during GSoC 2019[edit]

1. SWIG wrapper for various binaries called by apertium mode files i.e. lt-proc, lrx-proc, apertium-transfer, apertium-interchunk, apertium-postchunk, apertium-pretransfer, apertium-tagger, cg-proc and their implementation in apertium-python with a subprocess fallback in absence of wrappers. The initialized wrapper objects are also stored for optimising the successive calls.

2. Installer for project on Ubuntu and Windows by executing `python setup.py install` which internally installs `aperitum-all-dev`, aperitum-eng & aperitum-en-es language package and also installs the wrapper binaries on Ubuntu.

3. Added support for tagger

4. Updated the documentation with changes in apertium python

Experience[edit]

Overall, it was a wonderful and satisfying journey. I had a great learning experience and a great time coding. Debugging the wrapper had its own set of challenges. I got stuck in the debugging task for a some time during the GSoC period. Hadn't been there the help from my mentor and other member of Apertium, I don't think I could have fixed those bugs. Fortunately all these issues got fixed and I was able to complete the wrapping process within time

Endnote[edit]

Thanks a lot to all members of apertium. I was very fortunate to get this opportunity to work with this wonderful organisation. My mentor Sushain Cherivirala & the apertium members are very helpful and this project wouldn't be possible without their constant help and guidance. I would really like to thank all of them.
