### Dataset Summary

  CatalanQA: It is an aggregation and balancing of 2 previous datasets: VilaQUAD and ViquiQUAD, which were described in 

This dataset can be used to build extractive-QA and Language Models.

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.

### Supported Tasks and Leaderboards
Extractive-QA, Language Model.
### Languages
Catalan (`ca`).

          "context": "El Ministeri d'Interior espanyol enviarà a Catalunya els 521 policies espanyols que han obtingut més mala nota a les oposicions. 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.",

### Data Fields
Follows [Rajpurkar, Pranav et al., 2016](http://arxiv.org/abs/1606.05250) for SQUAD v1 datasets.
- `id` (str): Unique ID assigned to the question.
- `title` (str): Title of the Wikipedia article.
- `context` (str): Wikipedia section text.
- `question` (str): Question.
- `answers` (list): List of answers to the question, each containing:
  - `text` (str): Span text answering to the question.
  - `answer_start` Starting offset of the span text answering to the question.

## Dataset Creation
### Methodology
Aggregation and balancing from ViquiQUAD and VilaQUAD datasets.
### Curation Rationale
For compatibility with similar datasets in other languages, we followed as close as possible existing curation guidelines. 
### Source Data
- https://www.vilaweb.cat and https://ca.wikipedia.org
#### Initial Data Collection and Normalization

#### Who are the source language producers?
[More Information Needed]
### 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. “SQuAD: 100, 000+ Questions for Machine Comprehension of Text.” EMNLP (2016)](http://arxiv.org/abs/1606.05250)).
#### 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
[More Information Needed]
### Discussion of Biases
[More Information Needed]
### Other Known Limitations
[More Information Needed]
