Dataset Summary

This dataset can be used to build extractive-QA and Language Models. It is an aggregation and balancing of 2 previous datasets: VilaQuAD and ViquiQuAD.

Splits have been balanced by kind of question, and unlike other datasets like SQuAD, it only contains, per record, one question and one answer for each context, although the contexts can repeat multiple times.

This dataset was developed by BSC TeMU as part of Projecte AINA, to enrich the Catalan Language Understanding Benchmark (CLUB).

Supported Tasks and Leaderboards

Extractive-QA, Language Model.

Languages

The dataset is in Catalan (ca-ES).

Segons que explica El País, hi havia mig miler de places vacants que s'havien de cobrir, però els agents amb més bones puntuacions han elegit destinacions diferents. En total van aprovar les oposicions 2.600 aspirants. D'aquests, en seran destinats al Principat 521 dels 560 amb més mala nota. Per l'altra banda, entre els 500 agents amb més bona nota, només 8 han triat Catalunya. Fonts de la policia espanyola que esmenta el diari ho atribueixen al procés d'independència, al Primer d'Octubre i a la 'situació social' que se'n deriva.",

  • title (str): Title of the article.
  • context (str): Article text.
  • question (str): Question.
  • answers (list): Answer to the question, containing:
    • text (str): Span text answering to the question.
    • answer_start Starting offset of the span text answering to the question.

Data Splits

  • train.json: 17135 question/answer pairs
  • dev.json: 2157 question/answer pairs
  • test.json: 2135 question/answer pairs

Dataset Creation

Curation Rationale

We created this corpus to contribute to the development of language models in Catalan, a low-resource language.

Source Data

Initial Data Collection and Normalization

This dataset is a balanced aggregation from ViquiQuAD and VilaQuAD datasets.

Who are the source language producers?

Volunteers from Catalan Wikipedia and professional journalists from VilaWeb.

Annotations

Annotation process

We did an aggregation and balancing from ViquiQuAD and VilaQuAD datasets.

To annotate those datasets, we commissioned the creation of 1 to 5 questions for each context, following an adaptation of the guidelines from SQuAD 1.0 (Rajpurkar, Pranav et al., 2016).

For compatibility with similar datasets in other languages, we followed as close as possible existing curation guidelines.

Who are the annotators?

Annotation was commissioned by a specialized company that hired a team of native language speakers.

Personal and Sensitive Information

No personal or sensitive information is included.

Considerations for Using the Data

Social Impact of Dataset

We hope this corpus contributes to the development of language models in Catalan, a low-resource language.
