Multi30K: Multilingual English-German Image Descriptions.

We introduce the Multi30K dataset to stimulate multilingual multimodal research. Recent advances in image description have been demonstrated on Englishlanguage datasets almost exclusively, but image description should not be limited to English. This dataset extends the Flickr30K dataset with i) German translations created by professional translators over a subset of the English descriptions, and ii) German descriptions crowdsourced independently of the original English descriptions. We describe the data and outline how it can be used for multilingual image description and multimodal machine translation, but we anticipate the data will be useful for a broader range of tasks.
