Why is it that you are interested in learning about machine translation?

Born as a Vietnamese in Vietnam, I have learning English since I was a kid, since it has always been deemed as an essential tool for people in my generation. However, I also understand that because learning a language not only takes time, effort and dedication but also a lot of money, not everyone has the opportunity and resources to do so. Therefore, in my opinion, machine translation is a useful alternative for people who wish to approach resources in other languages for their careers and life enjoyments.

Why are you interested in Apertium project?

First of all, since Apertium is an open-source project, everyone can contribute and I think that this system is perfect for language translation. Since languages are created by, developed by, affected by, and used by people, they require human involvement and interactions, and therefore it's great for many people to work on one project. In addition, the platform is also very open, in that people of various backgrounds and experiences can join and contribute (which is the reason why I want to do so).
Second, despite having no immediate relations, there are many similarities in the grammar structures of the specific pair of language that I'm thinking about (Vietnamese<->English), and therefore I believe that the rule-based MT Apertium can provide a great system for translation between this pair.

I'm interested in GSOC for Apertium in particular because even though I've decided that I would like to contribute no matter what the result will be, participating in GSOC and having a mentor who knows Apertium well will be a greater help for me to get more experience in the field (coding as well as linguistic knowledge). In my opinion, just discussing about an issue can lead to good solutions, and a mentor's advice are always appreciated.

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

I'm interested in Adopting an unreleased pair, specifically the pair Vietnamese - English.

Proposal

Why Google and Apertium should sponsor it

Although Vietnamese is spoken by around 80 million people as their first language in Vietnam, as well as other millions of people in the US, Australia, Canada, Germany and so on, there is not much work in progress on supporting the translation of Vietnamese to other languages.

A part of the Austroasiatic family, Vietnamese is considered to be closely related to some languages and dialects spoken in Cambodia, Thai, Laos, India, Bangladesh. In addition, having been under Chinese occupation for centuries, the language is also much similar to Cantonese in sounds and grammar. Therefore, the rules created from this project can be useful for some other dialects , especially ones that are less often represented.

I'm aware that there are other MT available for Vietnamese-English translation (Microsoft, Google, and one by a Vietnamese company that is very slow and only works for short sentences), among which Google Translation seems to be the best one. I have only been able to manually test these machines, and found that while Google's coverage is great for monosyllabic words, many bi- or polysyllabic words that make up a large part of Vietnamese are not recognized and translated as monosyllables, making little sense. In addition, the grammar and lexical selection of the system also seem to require much more work. I understand that it's impossible to create a fluent translation system in three months, but it should be enough to create a good framework for future continuing development.

How and who it will benefit in the society

Vietnamese speakers, especially monolingual speaker, will. That is to say, at least 80 millions people. As stated above, studying a language is costly in terms of time and money, and a MT is a feasible alternative, since more and more people these days are also getting access to the Internet. With this machine, reading of news, documents as well as exchanging of ideas will be made easier for Vietnamese who hope to interact more with people from other countries, and the MT will also open a bigger door for non-Vietnamese speakers who hope to learn more about the language as well as the country.

List your skills and give evidence of your qualifications

I'm a junior in Smith College, USA but Computer Science experience-wise, I'm a sophomore. I've had experience coding in Python, Java, with a summer working on CSS, Artificial Intelligence. I've been learning Japanese- my third language for two years in America, and one year in Japan (currently). Apertium is my first open source project, but it's been nice so far, and I will definitely continue contributing.

Non-GSOC schedule

I don't have any other plans for the summer, and I'm willing to spend 40 hours a week on Apertium because I think that that's the time I will need to complete my goals.
