| TyDi QA is a question answering dataset covering 11 typologically diverse languages with 204K question-answer pairs. | |
| The languages of TyDi QA are diverse with regard to their typology -- the set of linguistic features that each language | |
| expresses -- such that we expect models performing well on this set to generalize across a large number of the languages | |
| in the world. It contains language phenomena that would not be found in English-only corpora. To provide a realistic | |
| information-seeking task and avoid priming effects, questions are written by people who want to know the answer, but | |
| don’t know the answer yet, (unlike SQuAD and its descendents) and the data is collected directly in each language without | |
| the use of translation (unlike MLQA and XQuAD). | |
