| − | '''What I want to get out of GSoC''' |
||
| − | |||
| − | I’ve studied about apertium and it’s amazing to me that I get an opportunity to work with them. NLP is what I want to do in life and working with a team to develop tools that actual people use will be invaluable experience that classes simply cannot match. Of course, the stipend is a big plus! |
||
| − | |||
| − | === Why is it that I am interested in Apertium and Machine Translation? === |
||
| − | |||
| − | Apertium is an Open Source Rule-based MT system. I have been part of the Machine Translation lab in my college and it interests me because it’s a complex problem and is often called NLP-Complete by my professors, i.e. it uses most of the tools NLP has to offer and hence if one learns to do good MT they learn most of Natural Language Processing. |
||
| − | |||
| − | Each part of Apertium's mission statement, especially the fact that they focus on Low Resource Languages, interests me and excites me to be working with them. While Neural Networks and Deep Learning is the fad these days, it only works for resource rich languages. |
||
| − | |||
| − | A tool which is rule based and open source really helps the community with language pairs that are resource poor and gives them free translations for their needs. I'm interested in working with Apertium and GSoC so that I can contribute to helping the community through the project. |
||
| − | |||
| − | == Project Proposal == |
||
| − | === Which of the published tasks am I interested in? What do I plan to do? === |
||
| − | |||
| − | Anaphora Resolution - Apertium currently uses default male. I don’t plan to make a perfect anaphora resolution in 3 months, but I can make one which uses complex features to pick an antecedent. I am confident that it will increase the fluency and intelligibility of output significantly. |
||
| − | |||
| − | The Anaphora Resolution tool will be language agnostic and will improve the output for most language pairs in Apertium. Pronouns are present in a lot of languages and they change based on their antecedent's gender, number, person, etc. This tool will figure out the antecedent and will choose the correct pronoun accordingly. |
||
| − | |||
| − | Sentences like “The group agreed to release his mission statement”, "The girl ate his apple" are grammatically incoherent and an incorrect pronoun will more often than not confuse people in complex sentences. |
||
| − | |||
| − | What puts people off Machine Translation is the lack of fluency, and this tool will definitely generate more fluent sentences leading to more trust in this tool. |
||
| − | |||
| − | === Proposed Modifications === |
||
| − | |||
| − | I will be working with Spanish-English and Catalan-English pairs while developing the tool. However, the features will be made largely language agnostic and I will also evaluate how well it works for other language pairs which need Anaphora Resolution. |
||
| − | |||
| − | Ultimately, the system should be able to do Anaphora Resolution for the following: |
||
| − | |||
| − | * '''Pronouns''' |
||
| − | |||
| − | Spanish Sentence: La chica es aquí, está vistiendo un vestido rojo |
||
| − | |||
| − | Apertium Translation: The girl is here, is dressing a red dress |
||
| − | |||
| − | After Anaphora [Proposed Translation]: The girl is here, '''she''' is dressing/wearing a red dress |
||
| − | |||
| − | * '''Possessive Pronouns''' |
||
| − | |||
| − | Spanish Sentence: La chica comió su manzana |
||
| − | |||
| − | Apertium Translation: The girl ate his apple |
||
| − | |||
| − | After Anaphora [Proposed Translation]: The girl ate '''her''' apple |
||
| − | |||
| − | * '''Zero Pronouns''' |
||
| − | |||
| − | Spanish Sentence: canta bueno |
||
| − | |||
| − | Apertium Translation: It sings well |
||
| − | |||
| − | After Anaphora [Proposed Translation]: He/She/It sings well (Based on context) |
||
| − | |||
| − | === Work Plan === |
||

||
| − | |||
| − | === A description of how and who it will benefit in society === |
||
| − | |||
| − | It will definitely benefit most users of Apertium and hopefully will attract more people to the tool. I’m from India and for a lot of our languages we don’t have the data to create reliable Neural MT systems. Similarly, for all resource poor languages, Apertium provides an easy and reliable MT system for their needs. That’s how Apertium benefits society already. |
||
| − | |||
| − | However, what discourages people from using Machine Translation is unintelligible outputs and too much post editing which makes it very time consuming and costly for them. While Apertium aims to make minimal errors, as of now it selects a default male pronoun and that leads to several unintelligible outputs. Fixing that and making the system more fluent and intelligible overall will encourage people to use Machine Translation and will reduce costs of time and money. |
||
| − | |||
| − | === Reasons why Google and Apertium should sponsor it === |
||
| − | |||
| − | I feel this project has a wide scope as it can affect almost all language pairs and helps almost everyone using Apertium. A decent Anaphora Resolution will give the output an important boost in its fluency and intelligibility, not just for one language, but all of them. |
||
| − | |||
| − | It’s a project which has promising future prospects as well - apart from the fact that language specific features can be added to improve it, we’ll be doing anaphora resolution even for languages which don’t need it to pick the correct pronoun. Doing this will enable Apertium to do Gisting Translation in the future, for which Anaphora Resolution is essential. |
||
| + | '''Hobbies:''' I enjoy playing the bass, singing, reading, and used to be super into Parliamentary Debating in uni. |
||
| − | With this project I aim to help the users of Apertium, I wish to become a regular contributor to Apertium and become equipped to do a lot more Open Source Development in the future for other organisations as well. |
||
| + | == Ideas == |
||
| − | By funding this project, Google will help improve an important Open Source tool and promote Open Source Development. In a world of Proprietary softwares, this is an invaluable resource for society and supports innovation that everyone can benefit from. |
