SQAC

The Spanish Question Answering Corpus (SQAC) is an extractive QA dataset with no unanswerable questions. It is created from texts extracted from the Spanish Wikipedia, encyclopedic articles, newswire articles from Wikinews, and the Spanish section of the AnCora corpus, which is a mix from different newswire and literature sources. It was created by commissioning the creation of 18,817 questions with the annotation of their answer spans from 6,247 textual contexts. The guidelines were adapted from SQuAD v1.1 (Rajpurkar et al., 2016), and the annotators were all native Spanish speakers with university studies in various fields related to linguistics. Following the XQuAD (Artetxe, Ruder, and Yogatama, 2019) structure, no additional answers were collected.
