 The source data are scraped articles from the [Catalan wikipedia](https://ca.wikipedia.org) site.
 
-From a set of high quality, non-translation, articles in the [Catalan Wikipedia](http://www.ca.wikipedia.org), 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)](http://arxiv.org/abs/1606.05250)). In total, 15153 pairs of a question and an extracted fragment that contains the answer were created.
