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", 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.

Dataset Summary

Split	Source dataset	Dimension	Rows	Languages
alpaca	Stanford Alpaca	Helpful	4,500	English, Urdu
beavertails	PKU-Alignment/BeaverTails	Harmless	12,583	English, Urdu
truthfulqa	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:

pip install pandas
python3 scripts/load_data.py

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:

from datasets import load_dataset

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

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/ directory contains the original evaluation code used in the paper, for Helpful/Harmless/Honest scoring in both English and Urdu.

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:

python3 Evaluations/run_all_evaluations.py

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

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

TruthfulQA, GPT-J judge workflow, English:

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:

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:

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 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.

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.
