• Title: Shiksha: A Technical Domain focused Translation Dataset and Model for Indian Languages
• Authors: Advait Joglekar, Srinivasan Umesh,
• Abstract summary: We create a parallel corpus containing more than 2.8 million rows of English-to-Indic and Indic-to-Indic high-quality translation pairs across 8 Indian languages. We finetune and evaluate NMT models using this corpus and surpass all other publicly available models at in-domain tasks.

• Abstract: Neural Machine Translation (NMT) models are typically trained on datasets with limited exposure to Scientific, Technical and Educational domains. Translation models thus, in general, struggle with tasks that involve scientific understanding or technical jargon. Their performance is found to be even worse for low-resource Indian languages. Finding a translation dataset that tends to these domains in particular, poses a difficult challenge. In this paper, we address this by creating a multilingual parallel corpus containing more than 2.8 million rows of English-to-Indic and Indic-to-Indic high-quality translation pairs across 8 Indian languages. We achieve this by bitext mining human-translated transcriptions of NPTEL video lectures. We also finetune and evaluate NMT models using this corpus and surpass all other publicly available models at in-domain tasks. We also demonstrate the potential for generalizing to out-of-domain translation tasks by improving the baseline by over 2 BLEU on average for these Indian languages on the Flores+ benchmark. We are pleased to release our model and dataset via this link: https://huggingface.co/SPRINGLab.

  We analyze the challenges and propose techniques that can be tailored for Multilingual Named Entity Recognition for Indian languages. We present a human annotated named entity corpora of 40K sentences for 4 Indian languages from two of the major Indian language families. We achieve comparable performance on completely unseen benchmark datasets for Indian languages which affirms the usability of our model.

  In Africa, and the world at large, there is an increasing focus on developing Neural Machine Translation (NMT) systems to overcome language barriers. In this project, we created the first sba-Fr dataset, which is a corpus of Ngambay-to-French translations. Our experiments show that the M2M100 model outperforms other models with high BLEU scores on both original and original+synthetic data.

  Machine translation is an effective approach to convert text to a different language without any human involvement. In this paper, we have applied NMT on two of the most morphological rich Indian languages, i.e. English-Tamil and English-Malayalam. We proposed a novel NMT model using Multihead self-attention along with pre-trained Byte-Pair-Encoded (BPE) and MultiBPE embeddings to develop an efficient translation system.
