Why is it that you are interested in Apertium?

I belong to India, a country with 22 different spoken languages and 720 dialects. Being from a nation with vast languages and a student of Computer Science, I strive to solve the problems in language translation through my knowledge of programming and natural language processing. I face difficulty when I travel to different regions and communicate with different people. I like the concept of Apertium as an open source language translator as it solves the problem of language translation with ease. As I am a student of Computer Science, I have a keen interest in programming and development. I am proficient in web development and want to apply my knowledge of machine translation by contributing in Apertium. I have an urge to improve open source language translation with Apertium.

Which of the published tasks are you interested in? What do you plan to do?

I am planning to work on the either or both of the listed projects:

  1. Python API/library for Apertium
  2. Improvements to the Apertium website

As I am skilled in web development and have appropriate experience working on it, I decided to work on improving Apertium website by contributing to its API called APy and also improve the frontend of the website for better user experience along addition of new functionality.

Why Google and Apertium should sponsor it?

I have a proper knowledge and experience with development in Python, C++ and JavaScript. Moreover I worked on several projects including areas like web development, opencv, machine learning and natural language processing. The libraries of apertium are written in C++ which is low level language. As people prefer high level languages like python, C++ packages need to be made available by writing APIs for python using SWIG. SWIG allows C++ libraries to be used flexibly with scripting languages such as python. I also want to add complete windows support for Apertium.

How and who it will benefit in society?

As most people use Windows, adding support for windows will increase the user base of Apertium. A pip install for windows would make development process a lot easier for the developers. Adding certain capabilities of Apertium such as dictionary/synonym lookup and webpage translation to the website would help in increasing the users and expand the uses of Apertium.

I am pursuing my degree of Bachelor of Technology in Computer Science Engineering at IIIT Una, India. I am a student of second year enrolled in a four year course of CSE. I have completed my intermediate with 95.2% marks with computer science as additional subject.


I have been studying Computer Science for 6 years now, with working experience in core programming languages such as Java, C++, Python, Javascript. I have been a part of several hackathons at college level. I am proficient in competitive programming and algorithm development. I have worked on several projects and build several professional websites many of which can be found on Github. I have been contributing to open source for quite a while now and have worked on several machine learning models in Python and R. Here is my github timeline :


Non-summer of code plans

Google Summer of Code lies during the summer vacations of the college. I will be able to devote 40 hours per week and more if necessary to Apertium during summer of code. I might have a small vacation plan but that lies in between the Community bonding period and I will be able to manage my work accordingly. I also acknowledge that GSOC is my foremost priority and I won’t be working on any other internship, training or classes if selected for GSOC.
