  We introduce Mintaka, a complex, natural, and multilingual dataset designed
for experimenting with end-to-end question-answering models. Mintaka is
composed of 20,000 question-answer pairs collected in English, annotated with
Wikidata entities, and translated into Arabic, French, German, Hindi, Italian,
Japanese, Portuguese, and Spanish for a total of 180,000 samples. Mintaka
includes 8 types of complex questions, including superlative, intersection, and
multi-hop questions, which were naturally elicited from crowd workers. We run
baselines over Mintaka, the best of which achieves 38% hits@1 in English and
31% hits@1 multilingually, showing that existing models have room for
improvement. We release Mintaka at https://github.com/amazon-research/mintaka.
