ViquiQuAD, An extractive QA dataset for Catalan, from the Wikipedia

Dataset Summary

ViquiQuAD, An extractive QA dataset for Catalan, from the Wikipedia.

This dataset contains 3111 contexts extracted from a set of 597 high quality original (no translations) articles in the Catalan Wikipedia "Viquipèdia", and 1 to 5 questions with their answer for each fragment.

Viquipedia articles are used under CC-by-sa licence.

This dataset can be used to fine-tune and evaluate extractive-QA and Language Models.

El reportatge fotogràfic implica més la idea de relat: un treball que vol més dedicació de temps, un esforç d'interpretació d'una situació i que culmina en un conjunt d'imatges. Això implica, d'una banda, la reivindicació del fotògraf per opinar, fet que li atorgarà estatus d'autor; l'autor proposa, doncs, una interpretació pròpia de la realitat. D'altra banda, el consens que s'estableix entre la majoria de fotògrafs és que el vehicle natural de la imatge fotogràfica és la pàgina impresa. Això suposà que revistes com Life, Paris-Match, Stern o Época assolissin la màxima esplendor en aquest període.",

Dataset Creation

Curation Rationale

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

Source Data

Initial Data Collection and Normalization

The source data are scraped articles from the Catalan wikipedia site.

From a set of high quality, non-translation, articles inCA the Catalan Wikipedia, 597 were randomly chosen, and from them 3111, 5-8 sentence contexts were extracted. We commissioned creation of between 1 and 5 questions for each context, following an adaptation of the guidelines from SQuAD 1.0 (Rajpurkar, Pranav et al. (2016)). In total, 15153 pairs of a question and an extracted fragment that contains the answer were created.

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

Who are the source language producers?

Volunteers who collaborate with Catalan Wikipedia.

Annotations

Annotation process

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)).

Who are the annotators?

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

Personal and Sensitive Information

No personal or sensitive information included.

Considerations for Using the Data

Social Impact of Dataset

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