### 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 coprpus<https://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](https://huggingface.co/datasets/unimelb-nlp/Multi-EuP/viewer/default/train) 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_Wiki`: A string specifying the gender of the MEP as mentioned on Wikipedia.
- `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.
