Human Benchmark Version v3

Parallel sentence benchmarks for the following language pairs:

  • English–Hindi
  • English–Telugu
  • Hindi–Telugu

This repository includes multiple domains, reference translations, and balanced splits for development and evaluation.

Source Data Layout

Raw data is organized by language pair and domain:

  • English-Hindi/
    • wiki-articles/
    • wiki-news/
    • news-on-air/
  • English-Telugu/online/
    • wiki-articles/
    • wiki-news/
    • news-on-air/

Each raw .txt file is tab-separated. The first three columns are:

  1. Task or passage id (varies by file)
  2. Source sentence (English)
  3. Target sentence (Hindi or Telugu)

Processed Outputs

All generated files are stored under outputs/.

1) Flat Parallel Pairs

Source–target TSVs (one sentence pair per line):

  • outputs/english-hindi.tsv
  • outputs/english-telugu.tsv
  • outputs/hindi-telugu.tsv

For Hindi–Telugu, pairs are created by matching shared English sentences across the English–Hindi and English–Telugu datasets.

2) Grouped References (per source)

One row per source sentence, followed by all references:

  • outputs/english-hindi.references.tsv
  • outputs/english-telugu.references.tsv
  • outputs/hindi-telugu.references.tsv

Format:

source<TAB>reference1<TAB>reference2<TAB>reference3...

3) Domain-Specific Splits with References

Split files are created per language pair, per domain, and per reference (ref1, ref2, ref3). Each split has an equal number of examples.

Location:

outputs/splits/

Filename pattern:

{pair}.{domain}.ref{1|2|3}.{dev|devtest|test}.tsv

Example:

english-hindi.wiki-news.ref1.dev.tsv

4) Grouped by Language and Reference

Domain-concatenated files grouped by language pair and reference:

outputs/grouped/{pair}/ref{1|2|3}/{dev|devtest|test}.tsv

Example:

outputs/grouped/english-hindi/ref1/dev.tsv

Splitting Policy

For each language pair and domain, sources are shuffled and split into dev, devtest, and test with equal sizes. Any remainder that would make the splits uneven is dropped.

Notes

  • All files are UTF-8.
  • Tabs are used as field separators.
  • If a source has fewer than 3 references, ref2/ref3 may be empty.
