Who am I?: I'm a Undergraduate Computer Science Student, in 3rd year of college from GGS Indraprastha University, New Delhi. I'm interested in Machine Learning and Natural Language Processing, and always seek to find ways to improve stuff based on them. I love talking about technology, AI, and Cyberpunk 2077.

FOSS Software I have used: My Work always involve FOSS Software and Frameworks, from Python to Tensorflow, from Ubuntu to Arch Linux, I've used many and tried to tweak the software that I use. I have tried to contribute to some of the FOSS Frameworks as well. And I have taken Part in Making some open source projects as well of my own.

Languages I know: Hindi(Native), English

Skills and Knowledge

I'm a Computer Science Student in my 3rd year of College

Languages that I know:

   1. Python
   2. C/C++
   3. Java
   4. JavaScript

Languages that I have worked and I'm familiar with:

   1. Julia
   2. Bash

Machine Learning, Deep Learning, and Natural Language Processing.

   ML Frameworks that I've worked with: Tensorflow, PyTorch, Spacy, Gensim, nltk, Flair, AllenNlp, openCV etc.
   Data Visualisation and stats libraries: pandas, numpy, seaborn, plotly, matplotlib, scipy etc.
   I've taken Online as well as offline courses to hone up my skills in the field.
   Not only this I've work with projects regaridng the same and I'm currently writing a research paper on Information Retrieval and Extraction
  (Stalled due to sudden college closure coz of CORONA Virus Pandemic).

Cources that I've taken during my college time (Only Relevant to project):

   1. Mathematics (I-IV, it includes stats, calculus(both), and linear algebra)
   2. Computer Programming
   3. AI
   4. Data Structures
   5. Algorithm Design and Analysis

Why is it that you are interested in Machine Translation?

Machine Translation is one such field that tells us about how tasks like translating languages and serving humanity can be done easily, and not only this, it tells about the scope of how things can be in future, I'm interested in Mahcine Translation because I'm interested in discovering ways to improve it further and with more feautures, and the project I'm interested in working with does the same. To improve machine-translation by mining post-edits, and learn based on it.

Why is it that you are interested in Apertium?

Apertium was one of the first Machine Translating Tool invented in the early 2000's in Spain. Till then and since now, it has helped a lot of people translating languages and it's the only Machine Translating Tool/Engine that works offline as well as works with Low Resource lanugages. Not only this, it's an Open Source and free software for all, and it allows learning students to reasearch and work with them. Working with the Apertium Team(Mentors, and people) is a great opportunity to learn and improve one such great tool to newer accuracy measures and feautures.Not only this, but it also provides resources to learn and research with tools like the Morphological Dictionaries, Transfer Rules, Stream-Parser which can be used to create other tools as well for eg. Automatic Post-Editing tool to create dictionary entries after learning from it. etc.

My Proposal

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

I'm interested in the Project: Automatic Post-Editing, Mining Post-Editing Dumps(Parallel Corpora) to improve Translation under the Mentor: Mikel L. Forcada (More Mentors to be added). The Project Aims to find the difference in translation by the Apertium Machine Translation, and the Human Post-Edited and takes appropriate measures and learning algorithms to define the problems/mis-translations for the same and creates the required into information that can be inserted in that Apertium language pair. These information can be either:

  • Dictionaries
  • Constraint Grammar Rules
  • Lexical Selection Rules

Task Description

The main goal of the Project Automatic Post-Editing, Mining Post-Editing Dumps(Parallel Corpora) to improve Translation is to create automatically Dictionary Entries (Monodix, Bidix) as automatically and complete by miniming Post-Editing Dumps(Human Verified Parallel Corpora) to improve translation, and performance of an Apertium Language Pair, a long goal of this will be to automate the process of creating/enriching the Built Language Pairs that are under-incubation.

The Project Consists of two phases :

First Phase

In this phases the Data needs to gathered and converted into specific format, or Post-Editing Operators:

  • S : Source Text
  • MT(S): Machine Translation of S
  • PE(S) or PE(MT(S)): The Post-Edited Sentence (Considered to be accurate)

Now then from this a structruted data needs to be created, possibly a Pandas DataFrame (CSV, JSON) for Different Languages.


Second Phase

For this phase the morphological data generated by Apertium's Stream Parser will be used to get the tags/operations of each text. And comparision of the PE and MT of S, will yield some information that can be used to improve the Apertium Language Pair by creating Dictionary, Grammar, Lexical Selection Rules.

Process

The Rationale for this Process is described at [Rationale[3]]
