| − | '''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. Each part of their mission statement interests me and excites me to be working with them. I have been part of the Machine Translation lab in my college and it interests me because it’s a huge 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. |
||
| − | |||
| − | While Neural Networks, Deep Learning is the fad these days, they only work for resource rich languages and that’s why I feel a project which is rule based and open source really helps the community with language pairs that our resource poor and gives them free translations for their needs. |
||
| − | |||
| − | == Project Proposal == |
||
| − | === Which of the published tasks am I interested in? What do I plan to do? === |
||
| − | |||
| − | Anaphora Resolution - Currently uses default male. I don’t plan to make a perfect anaphora resolution in 3 months, but I’m confident that I can make one which works significantly better than the default male and it can increase the fluency and intelligibility of output by a lot. |
||
| − | |||
| − | The Anaphora Resolution tool will be language agnostic and hence this project affects almost all language pairs in apertium and hence it affects almost everyone using the tool. Pronouns are present in a lot of languages and with gendered pronouns, singular, plural, etc., we need to find out what they refer to. Why is this important? |
||
| − | |||
| − | A sentence like “The group agreed to release his mission statement” is grammatically incoherent and an incorrect pronoun will more often than not confuse people in more complex sentences. |
||
| − | |||
| − | What puts people off Machine Translation is the lack of fluency, and I feel this is an important contribution to fluency and will definitely generate more fluent sentences leading to more trust in this tool. |
||
| + | '''Professional Interests:''' I’m currently doing research in Computational Linguistics and I have a particular interest in Linguistics and NLP tools, specifically Machine Translation and its components. |
||
| − | === Work Plan === |
||
| + | '''Hobbies:''' I enjoy playing the bass, singing, reading, and used to be super into Parliamentary Debating in uni. |

||
| − | * '''Project Completed''' |
||
| + | == Ideas == |
||
| − | === Additional Information === |
||
| − | * Agreement: Different for different languages? |
||
| − | * Agreement rules in Arabic, however, are different. For instance, a set of non- human items (animals, plants, objects) is referred to by a singular feminine pronoun. |
||
| − | * Since Arabic is an agglutinative language, the pronouns may appear as suffixes of verbs, nouns (e.g., in the case of possessive pronouns) and preposi- tions. |

| − | === Reasons why Google and Apertium should sponsor it === |
||
| + | == Google Summer of Code 2020 -- Markup handling with wordbound blanks == |
||
| − | I feel that this project affects almost all language pairs in apertium and hence it affects almost everyone using Apertium. A decent anaphora resolution will give the output an important boost in it’s fluency and intelligibility, not just for one language, but all of them. |
||
| − | It’s a project which has promising future prospects - 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, which is an important tool and anaphora resolution is an essential cog in that wheel. |
||
| + | '''Proposal: Modifying the apertium stream format and eliminating dictionary trimming: [[User:Khannatanmai/GSoC2020Proposal_Trimming]]''' |
||
| − | === 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. |
||
| + | Development of the stream extension: [[User:Khannatanmai/New_Apertium_stream_format]] |
||
| − | I feel that currently what repels people from Machine Translation is unintelligible outputs and too much post editing which makes it useless 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 should definitely attract people to using Machine Translation and help them to reduce costs of time and money. |
||
| + | Eliminating Dictionary Trimming: [[User:Khannatanmai/Eliminating_Dictionary_Trimming]] |
||
| − | == Skills and Qualifications == |
||
| − | I'm currently a third year student at IIIT Hyderabad where I'm studying Computational Linguistics. It is a dual degree where we study Computer Science, Linguistics, NLP, etc. right from the start. I've been interested in linguistics from the start and due to the rigorous programming courses, I'm also adept at several programming languages like Python, C++, etc. |
||
| + | '''Progress: [[User:Khannatanmai/GSoC2020Progress]]''' |
||
| − | Due to the focused nature of our course, I've worked in several projects, such as building Translation Memory, Detecting Homographic Puns, POS Taggers, Grammar and Spell Checkers, Named Entity Recognisers, Building Chatbots, etc. all of which required a working understanding of Natural Language Processing. |
||
| + | Documentation of features related to secondary tags: [[User:Khannatanmai/Secondary_tags_features]] |
||
| − | === Coding Challenge === |
||
| − | I successfully completed the coding challenge and proposed an alternate method to process the input as a chunk which resulted in a speedup of more than 2x. |
||
| + | Alternate stream modification proposal: [[User:Khannatanmai/Alternate_stream_modification]] |
||
| − | The repo can be found at: https://github.com/khannatanmai/apertium |
||
| + | Development of the updated stream extension: [[User:Khannatanmai/Secondary_info_apertium_stream_format]] |
||
| − | Files in Repo: |
||
| − | * Code to do basic anaphora resolution (last seen noun), input taken as a stream (byte by byte) |
||
| − | * Code to do basic anaphora resolution (last seen noun), input taken as a stream (as a chunk) |

||
| − | == Non-Summer-Of-Code Plans == |
||
| + | '''Documentation of wordbound blanks: [[Wordbound_blanks]]''' |
||
| − | I will have my college vacations during GSoC so will have no other commitments in that period and will be dedicated to GSoC full time, i.e. 40 hours a week. |
||
| + | '''Final Report: [[User:Khannatanmai/GSoC2020_Final_Report]]''' |
||
| − | I am planning to go on a short trip to London from 18 May to 25 May but I will have internet there and will be working a little less than normal but will catch up. |
