M2QA: Multi-domain Multilingual Question Answering

M2QA (Multi-domain Multilingual Question Answering) is an extractive question answering benchmark for evaluating joint language and domain transfer. M2QA includes 13,500 SQuAD 2.0-style question-answer instances in German, Turkish, and Chinese for the domains of product reviews, news, and creative writing.

This Hugging Face datasets repo accompanies our paper "M2QA: Multi-domain Multilingual Question Answering". If you want an explanation and code to reproduce all our results or want to use our custom-built annotation platform, have a look at our GitHub repository: https://github.com/UKPLab/m2qa

Loading & Decrypting the Dataset

Following Jacovi et al. (2023), we encrypt the validation data to prevent leakage of the dataset into LLM training datasets. But loading the dataset is still easy:

To load the dataset, you can use the following code:

from datasets import load_dataset
from cryptography.fernet import Fernet

# Load the dataset
subset = "m2qa.german.news" # Change to the subset that you want to use
dataset = load_dataset("UKPLab/m2qa", subset)

# Decrypt it
fernet = Fernet(b"aRY0LZZb_rPnXWDSiSJn9krCYezQMOBbGII2eGkN5jo=")

def decrypt(example):
    example["question"] = fernet.decrypt(example["question"].encode()).decode()
    example["context"] = fernet.decrypt(example["context"].encode()).decode()
    example["answers"]["text"] = [fernet.decrypt(answer.encode()).decode() for answer in example["answers"]["text"]]
    return example

dataset["validation"] = dataset["validation"].map(decrypt)

The M2QA dataset is licensed under a "no derivative" agreement. To prevent contamination of LLM training datasets and thus preserve the dataset's usefulness to our research community, please upload the dataset only in encrypted form. Additionally, please use only APIs that do not utilize the data for training.

Overview / Data Splits

All used text passages stem from sources with open licenses. We list the licenses here: https://github.com/UKPLab/m2qa/tree/main/m2qa_dataset

We have validation data for the following domains and languages:

Subset Name	Domain	Language	#Question-Answer instances
m2qa.german.product_reviews	product_reviews	German	1500
m2qa.german.creative_writing	creative_writing	German	1500
m2qa.german.news	news	German	1500
m2qa.chinese.product_reviews	product_reviews	Chinese	1500
m2qa.chinese.creative_writing	creative_writing	Chinese	1500
m2qa.chinese.news	news	Chinese	1500
m2qa.turkish.product_reviews	product_reviews	Turkish	1500
m2qa.turkish.creative_writing	creative_writing	Turkish	1500
m2qa.turkish.news	news	Turkish	1500

Additional Training Data

We also provide training data for five domain-language pairs, consisting of 1500 question-answer instances each, totalling 7500 training examples. These are the subsets that contain training data:

• m2qa.chinese.news
• m2qa.chinese.product_reviews
• m2qa.german.news
• m2qa.german.product_reviews
• m2qa.turkish.news

The training data is not encrypted.
