MQA

MQA is a Multilingual corpus of Questions and Answers (MQA) parsed from the Common Crawl. Questions are divided in two types: Frequently Asked Questions (FAQ) and Community Question Answering (CQA).

from datasets import load_dataset
all_data = load_dataset("clips/mqa", language="en")
{
  "name": "the title of the question (if any)",
  "text": "the body of the question (if any)",
  "answers": [{
    "text": "the text of the answer",
    "is_accepted": "true|false"
  }]
}
faq_data = load_dataset("clips/mqa", scope="faq", language="en")
cqa_data = load_dataset("clips/mqa", scope="cqa", language="en")

Languages

We collected around 234M pairs of questions and answers in 39 languages. To download a language specific subset you need to specify the language key as configuration. See below for an example.

load_dataset("clips/mqa", language="en") # replace "en" by any language listed below

FAQ vs. CQA

You can download the Frequently Asked Questions (FAQ) or the Community Question Answering (CQA) part of the dataset.

faq = load_dataset("clips/mqa", scope="faq")
cqa = load_dataset("clips/mqa", scope="cqa")
all = load_dataset("clips/mqa", scope="all")

Although FAQ and CQA questions share the same structure, CQA questions can have multiple answers for a given questions, while FAQ questions have a single answer. FAQ questions typically only have a title (name key), while CQA have a title and a body (name and text).

Nesting and Data Fields

You can specify three different nesting level: question, page and domain.

Question

load_dataset("clips/mqa", level="question") # default

The default level is the question object:

name: the title of the question(if any) in markdown format
text: the body of the question (if any) in markdown format
answers: a list of answers
- text: the title of the answer (if any) in markdown format
- name: the body of the answer in markdown format
- is_accepted: true if the answer is selected.

Page

This level returns a list of questions present on the same page. This is mostly useful for FAQs since CQAs already have one question per page.

load_dataset("clips/mqa", level="page")

Domain

This level returns a list of pages present on the web domain. This is a good way to cope with FAQs duplication by sampling one page per domain at each epoch.

load_dataset("clips/mqa", level="domain")

Source Data

This section was adapted from the source data description of OSCAR

Common Crawl is a non-profit foundation which produces and maintains an open repository of web crawled data that is both accessible and analysable. Common Crawl's complete web archive consists of petabytes of data collected over 8 years of web crawling. The repository contains raw web page HTML data (WARC files), metdata extracts (WAT files) and plain text extracts (WET files). The organisation's crawlers has always respected nofollow and robots.txt policies.

To construct MQA, we used the WARC files of Common Crawl.

People

This model was developed by Maxime De Bruyn, Ehsan Lotfi, Jeska Buhmann and Walter Daelemans.
