+### [Dataset Summary](#dataset-summary)
+
+We present MLSUM, the first large-scale MultiLingual SUMmarization dataset.
+Obtained from online newspapers, it contains 1.5M+ article/summary pairs in five different languages -- namely, French, German, Spanish, Russian, Turkish.
+Together with English newspapers from the popular CNN/Daily mail dataset, the collected data form a large scale multilingual dataset which can enable new research directions for the text summarization community.
+We report cross-lingual comparative analyses based on state-of-the-art systems.
+These highlight existing biases which motivate the use of a multi-lingual dataset.
