Filtered Multilingual Corpus (EN-HI-PA)

Dataset Description

A cleaned and balanced multilingual corpus extracted from the Samanantar dataset, containing parallel sentences in English, Hindi, and Punjabi.

Languages

The dataset contains text in three languages:

English (en)
Hindi (hi)
Punjabi (pa)

Dataset Summary

This dataset is a filtered subset of the Samanantar parallel corpus, specifically:

150,000 English sentences (from EN-HI and EN-PA parallel data)
150,000 Hindi sentences (from EN-HI parallel data)
150,000 Punjabi sentences (from EN-PA parallel data)

All sentences have been cleaned, deduplicated, and quality-filtered for language modeling purposes.

Supported Tasks

Multilingual language model training
Cross-lingual transfer learning
Machine translation fine-tuning
Multilingual text generation

Dataset Structure
