# Pak3H: A Pakistani-Urdu Alignment Dataset (Helpful / Harmless / Honest)

Pak3H is a bilingual (English–Urdu) dataset and evaluation suite from the
EMNLP 2026 paper [*"Pak3H: Evaluating the Cost of Cultural Mismatch in LLM
Alignment with a Human-Contextualized Urdu Benchmark"*](https://aclanthology.org/2026.emnlp-main.883/),
for studying RLHF-style alignment in a low-resource, culturally-situated
setting: Pakistani Urdu. It adapts three widely-used English alignment
benchmarks — covering **Helpfulness**, **Harmlessness**, and **Honesty** —
into Urdu through translation and cultural contextualization, while keeping
the original English text in the same row for direct comparison.

> **Content warning:** the `beavertails` split contains prompts and responses
> depicting unsafe, offensive, and otherwise harmful content (e.g. violence,
> hate speech, self-harm) by design, since it is a safety/harmlessness
> benchmark. See [Considerations and Limitations](#considerations-and-limitations).

## Dataset Summary

| Split | Source dataset | Dimension | Rows | Languages |
|---|---|---|---|---|
| [`alpaca`](data/alpaca) | [Stanford Alpaca](https://github.com/tatsu-lab/stanford_alpaca) | Helpful | 4,500 | English, Urdu |
| [`beavertails`](data/beavertails) | [PKU-Alignment/BeaverTails](https://github.com/PKU-Alignment/beavertails) | Harmless | 12,583 | English, Urdu |
| [`truthfulqa`](data/truthfulqa) | [TruthfulQA](https://github.com/sylinrl/TruthfulQA) | Honest | 817 | English, Urdu |

Each split is a **single bilingual CSV**: the original English columns plus
the corresponding culturally-contextualized Urdu columns (prefixed
`ctx_..._ur`), so every row can be compared across languages directly.
Urdu coverage is complete — every row has a non-empty Urdu translation
except where the English source field itself is empty.

## Quick Start

No installation beyond `pandas` is required to just inspect the data:

```bash
pip install pandas
python3 scripts/load_data.py
```

```python
import pandas as pd

df = pd.read_csv("data/alpaca/pak_alpaca.csv")
print(df.iloc[0][["instruction", "ctx_instruction_ur"]])
```

Or load a single split directly from this CSV, from a local clone or from the
Hugging Face Hub, by passing the split name as the `datasets` config:

```python
from datasets import load_dataset

ds = load_dataset("Hashmat0202/Pak3H", "truthfulqa")  # or "alpaca" / "beavertails"
```

## Data Fields

### `alpaca` — Helpfulness (instruction following)

| Column | Description |
|---|---|
| `instruction` | Original English instruction |
| `input` | Optional English input/context for the instruction (empty for ~61% of rows) |
| `output` | Original English reference output |
| `final_category` | Translation provenance for this row (see [Translation Provenance](#translation-provenance)) |
| `ctx_instruction_ur` | Culturally-contextualized Urdu instruction |
| `ctx_input_ur` | Culturally-contextualized Urdu input |
| `ctx_output_ur` | Culturally-contextualized Urdu output |

### `beavertails` — Harmlessness (safety)

| Column | Description |
|---|---|
| `prompt` | English prompt (3,500 unique prompts, ~3.6 responses each) |
| `response` | English candidate response to the prompt |
| `category` | Stringified dict of 14 harm-category booleans (see below) |
| `is_safe` | `True`/`False` — whether `response` is judged safe for `prompt` |
| `final_category` | Translation provenance for this row (see [Translation Provenance](#translation-provenance)) |
| `ctx_prompt_ur` | Culturally-contextualized Urdu prompt |
| `ctx_response_ur` | Culturally-contextualized Urdu response |

The 14 harm categories encoded in `category` (BeaverTails taxonomy):
`animal_abuse`, `child_abuse`, `controversial_topics,politics`,
`discrimination,stereotype,injustice`, `drug_abuse,weapons,banned_substance`,
`financial_crime,property_crime,theft`, `hate_speech,offensive_language`,
`misinformation_regarding_ethics,laws_and_safety`,
`non_violent_unethical_behavior`, `privacy_violation`, `self_harm`,
`sexually_explicit,adult_content`, `terrorism,organized_crime`,
`violence,aiding_and_abetting,incitement`.

### `truthfulqa` — Honesty (truthful question answering)

| Column | Description |
|---|---|
| `Type` | `Adversarial` or `Non-Adversarial` |
| `Category` | One of 38 topical categories (e.g. Misconceptions, Law, History) |
| `Question` | English question |
| `Best Answer` | Single best English reference answer |
| `Correct Answers` | `;`-separated list of acceptable English answers |
| `Incorrect Answers` | `;`-separated list of common English false answers |
| `Source` | Provenance URL for the question |
| `final_category` | Translation provenance for this row (see [Translation Provenance](#translation-provenance)) |
| `ctx_Question_ur` | Culturally-contextualized Urdu question |
| `ctx_Best Answer_ur` | Culturally-contextualized Urdu best answer |
| `ctx_Correct Answers_ur` | Culturally-contextualized Urdu correct answers |
| `ctx_Incorrect Answers_ur` | Culturally-contextualized Urdu incorrect answers |

### Translation Provenance

`final_category` records how each row's Urdu text was produced during
annotation and QA:

| Value | Meaning |
|---|---|
| `DT` | Direct Translation — rendered into Urdu with no cultural adaptation needed |
| `LC` | Locally Contextualized — adapted so references, names, and scenarios fit a Pakistani setting |
| `LI` | Localized-Identical — contextualization pass reviewed the row and kept it unchanged |
| `DISCARD` | Flagged during QA as low quality or out of scope; retained in the file but should be excluded from analysis that requires fully vetted rows |

## Statistics

- **Alpaca**: 4,500 rows — 4,119 `DT`, 358 `LC`, 22 `LI`, 1 `DISCARD`. 2,752 (61%) rows have no `input` field.
- **BeaverTails**: 12,583 prompt–response pairs over 3,500 unique prompts — 10,539 `DT`, 1,827 `LC`, 203 `LI`, 14 `DISCARD`. 7,008 (56%) labeled unsafe, 5,575 (44%) labeled safe.
- **TruthfulQA**: 817 questions across 38 categories — 516 `DT`, 200 `LC`, 99 `LI`, 2 `DISCARD`. 437 (53%) adversarial, 380 (47%) non-adversarial.

## How the Dataset Was Built

1. **Source sampling** — prompts/instructions/questions were drawn from the
   original English Alpaca, BeaverTails, and TruthfulQA releases.
2. **Cultural contextualization** — English source text was adapted so that
   references, names, idioms, and scenarios make sense in a Pakistani
   context, rather than translated purely literally.
3. **Urdu translation** — the contextualized text was rendered into Urdu
   with LLM assistance, followed by an independent LLM review pass that
   audited every row against the English source for omissions,
   mistranslation, and unnatural phrasing.
4. **Manual annotation and QA passes** — human annotators reviewed
   translation and contextualization quality, assigning the `final_category`
   label per row and flagging rows for discard where necessary.

## Running the Evaluations

The [`Evaluations/`](Evaluations) directory contains the original evaluation
code used in the paper, for Helpful/Harmless/Honest scoring in both English
and Urdu.

```bash
pip install -r requirements.txt
export OPENAI_API_KEY="your_key_here"   # for Alpaca-style and judge-based steps
export HF_TOKEN="your_hf_token_here"    # for gated Hugging Face models
```

Run everything bundled in the repo:

```bash
python3 Evaluations/run_all_evaluations.py
```

**BeaverTails safety score** (English vs. Urdu harmfulness via beaver-dam-7b):

```bash
python3 Evaluations/evaluate_beavertails_safety_score.py \
  --csv_path data/beavertails/pak_beavertails.csv \
  --sample_size 100
```

**TruthfulQA**, GPT-J judge workflow, English:

```bash
python3 Evaluations/TruthfulQA/gptj_end_to_end.py \
  --input_path data/truthfulqa/pak_truthfulqa.csv \
  --output_path Evaluations/TruthfulQA/outputs/gptj_answers.csv \
  --summary_path Evaluations/TruthfulQA/outputs/gptj_summary.csv \
  --metrics mc bleu rouge bleurt ti \
  --language en \
  --question_col Question \
  --best_answer_col "Best Answer" \
  --correct_answers_col "Correct Answers" \
  --incorrect_answers_col "Incorrect Answers" \
  --ti_question_col Question \
  --ti_sample_size 817 \
  --ti_seed 42 \
  --ti_delay 0.2
```

The same runner works for Urdu by switching to the `ctx_..._ur` columns:

```bash
python3 Evaluations/TruthfulQA/gptj_end_to_end.py \
  --input_path data/truthfulqa/pak_truthfulqa.csv \
  --output_path Evaluations/TruthfulQA/outputs/gptj_answers_ur.csv \
  --summary_path Evaluations/TruthfulQA/outputs/gptj_summary_ur.csv \
  --metrics mc bleu rouge bleurt ti \
  --language ur \
  --question_col ctx_Question_ur \
  --best_answer_col "ctx_Best Answer_ur" \
  --correct_answers_col "ctx_Correct Answers_ur" \
  --incorrect_answers_col "ctx_Incorrect Answers_ur" \
  --ti_question_col ctx_Question_ur \
  --ti_sample_size 817 \
  --ti_seed 42 \
  --ti_delay 0.2
```

**Swapping in a Hugging Face causal LM** (e.g. Llama 3 8B Instruct, Qwen2.5 7B
Instruct) for TruthfulQA:

```bash
python3 Evaluations/TruthfulQA/llama_single_file_end_to_end.py \
  --input_path data/truthfulqa/pak_truthfulqa.csv \
  --output_path Evaluations/TruthfulQA/outputs/llama3_answers.csv \
  --summary_path Evaluations/TruthfulQA/outputs/llama3_summary.csv \
  --model_name meta-llama/Meta-Llama-3-8B-Instruct \
  --chat_template_mode auto \
  --metrics mc bleu rouge ti \
  --language en \
  --sample_size 100 \
  --ti_sample_size 100
```

Only the `--model_name` changes for a different model (e.g.
`Qwen/Qwen2.5-7B-Instruct`). Use `HF_TOKEN` for gated models and
`--chat_template_mode off` for plain (non-chat) prompting.

**Alpaca-style pairwise evaluation** — `run_alpaca_eval_limited.py` wraps the
[`alpaca_eval`](https://github.com/tatsu-lab/alpaca_eval) library with a
GPT-4o-mini judge. It expects model/reference outputs already generated in
`alpaca_eval`'s JSON format under `Evaluations/alpaca_eval_results/` (see the
script for the exact filenames); generating those outputs from your own model
is left to your own inference pipeline.

```bash
python3 Evaluations/run_alpaca_eval_limited.py
```

Generated evaluation outputs are written under ignored `outputs/` /
`alpaca_eval_results/` folders — point `--output_path` / `--summary_path` at
your own location for a fresh run.

## Considerations and Limitations

- **Harmful content**: `beavertails` intentionally contains unsafe prompts
  and responses (violence, hate speech, self-harm, etc.) as part of its
  safety-evaluation design. Handle and distribute with care, and avoid using
  it to train models without a safety-filtering or moderation step.
- **LLM-assisted translation**: Urdu text was produced with LLM translation
  and an independent LLM review pass, plus human QA; residual translation
  artifacts may remain in a small number of rows.
- **`DISCARD` rows**: 17 rows across the three splits are flagged
  `final_category=DISCARD` from QA but retained in the files for
  transparency — filter them out if your analysis requires only fully
  vetted rows.
- **Not a train/test split**: these files are released as full splits, not
  pre-partitioned for training vs. evaluation — partition as needed for your
  use case.
