NOTES FOR DOWNLOAD!

1. Highly recommend downloading it via the API:

curl -X GET \
     "https://datasets-server.huggingface.co/first-rows?dataset=unimelb-nlp%2FMulti-EuP&config=default&split=full"

2. If you are using the HuggingFace library, please follow these steps:

pip install datasets

from datasets import load_dataset

dataset = load_dataset("unimelb-nlp/Multi-EuP", keep_default_na=False)

Note: It's crucial to use keep_default_na=False because some datasets contain 'null' values, such as qid_GA, due to the Irish (GA) debate titles not being published before it became an official EU language on 1 January 2022. Additionally, some debate text may not belong to the active 705 MEP, resulting in missing matching information.

Dataset Summary

The Multi-Eup is a new multilingual benchmark dataset, comprising 22K multilingual documents collected from the European Parliament, spanning 24 languages. This dataset is designed to investigate fairness in a multilingual information retrieval (IR) context to analyze both language and demographic bias in a ranking context. It boasts an authentic multilingual corpus, featuring topics translated into all 24 languages, as well as cross-lingual relevance judgments. Furthermore, it offers rich demographic information associated with its documents, facilitating the study of demographic bias.

Dataset Structure

The Multi-EuP dataset contains two files, debate coprpushttps://huggingface.co/datasets/unimelb-nlp/Multi-EuP/blob/main/Debates.csv and MEP info https://huggingface.co/datasets/unimelb-nlp/Multi-EuP/blob/main/MEPs.csv. The MEP id in two files can be used for alignment.

Debate Corpus Fileds

The debate instance and attributes are displayed below. See the Multi-EuP debate viewer to explore more examples.

• TEXT: A string representing the content of the debate speech.
• NAME: A string containing the name of the MEP who presented the speech.
• PRESIDENT: A boolean indicating whether the MEP is the president (typically discussing procedural matters to introduce the debate).
• MEPID: An integer representing the unique ID of the MEP in the EU.
• LANGUAGE: The language ISO code of the text.
• PARTY: A string representing the political party of the MEP.
• TEXTID: A hash string serving as a unique identifier for the speech text.
• CODICT: An integer serving as the unique identifier for the speech text.
• DATE: A string indicating the date when the debate happened.
• VOD-START: The timestamp of the speech start.
• VOD-END: The timestamp of the speech end.
• title_X: A string representing the title in language X (e.g., title_EN). Note that this field might be empty for some languages, such as GA, as the EU does not publish titles in Irish (GA).
• did: A string representing the unique ID of the text (e.g., doc0, doc1).
• qid_X: A string representing the unique ID of the title in language X (e.g., qid0#EN).

MEP info Fileds

The information dictionary for the 705 MEPs was constructed as follows:

• fullName: A string representing the full name of the MEP.
• politicalGroup: A string indicating the political group affiliation of the MEP.
• id: An integer representing the unique identifier of the MEP in the EU.
• nationalPoliticalGroup: A string denoting the national political group of the MEP.
• photo: A .jpg file containing the profile picture of the MEP.
• nameAudio: A .mp3 file with the pronunciation of the MEP's name.

• gender_2017: A string indicating the gender of the MEP according to europal-2017(https://aclanthology.org/E17-1101.pdf).
• gender: A string representing the MEP's gender after cross-referencing information from Wikipedia, europal-2017, and manual verification.
• dateOfBirth_Wiki: A string stating the date of birth of the MEP as mentioned on Wikipedia.
• dateOfBirth_Home: A string indicating the date of birth of the MEP as found on their homepage in the EU.
• dateOfBirth: A string representing the date of birth of the MEP after combining information from Wikipedia, their homepage, and manual verification.
• placeOfBirth: A string indicating the place of birth of the MEP as mentioned on their homepage.
• country: A string representing the nationality country of the MEP as mentioned on their homepage.
• homePage: A string providing the link to the MEP's homepage.
