+# 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.
