And #Google also launched #DataSet search. This is a huge breakthrough for the DS community, because now it will be easier to access some interesting data.

​​Rethinking Generalization of Neural Models: A Named Entity Recognition Case Study

Authors use the NER task to analyze the generalization behavior of existing models from different perspectives. Experiments with in-depth analyses diagnose the bottleneck of existing neural NER models in terms of breakdown performance analysis, annotation errors, dataset bias, and category relationships, which suggest directions for improvement.

The authors also release two datasets for future research: ReCoNLL and PLONER.

The main findings of the paper:
– the performance of existing models (including the state-of-the-art model) heavily influenced by the degree to which test entities have been seen in the training set with the same label
– the proposed measure enables to detect human annotation errors.

Once these errors are fixed, previous models can achieve new state-of-the-art results
– authors introduce two measures to characterize the data bias and the cross-dataset generalization experiment shows that the performance of NER systems is influenced not only by whether the test entity has been seen in the training set but also by whether the context of the test entity has been observed
– providing more training samples is not a guarantee of better results. A targeted increase in training samples will make it more profitable
– the relationship between entity categories influences the difficulty of model learning, which leads to some hard test samples that are difficult to solve using common learning methods

​​MLSUM: The Multilingual Summarization Corpus

The first large-scale MultiLingual SUMmarization dataset, comprising over 1.5M article/summary pairs in French, German, Russian, Spanish, and Turkish. Its complementary nature to the CNN/DM summarization dataset for English.

For each language, they selected an online newspaper from 2010 to 2019 which met the following requirements:
0 being a generalist newspaper: ensuring that a broad range of topics is represented for each language allows minimizing the risk of training topic-specific models, a fact which would hinder comparative cross-lingual analyses of the models.
1 having a large number of articles in their public online archive.
2 Providing human written highlights/summaries for the articles that can be extracted from the HTML code of the web page.

Also, in this paper, you can remember about similar other datasets
