Automatic generation of summaries from multiple news articles is a valuable tool as the number of online publications grows rapidly.Single document summarization (SDS) systems have benefited from advances in neural encoder-decoder model thanks to the availability of large datasets.However, multidocument summarization (MDS) of news articles has been limited to datasets of a couple of hundred examples.In this paper, we introduce Multi-News, the first large-scale MDS news dataset.Additionally, we propose an end-to-end model which incorporates a traditional extractive summarization model with a standard SDS model and achieves competitive results on MDS datasets.We benchmark several methods on Multi-News and release our data and code in hope that this work will promote advances in summarization in the multidocument setting 1 .
