PeerSum: A Peer Review Dataset for Abstractive Multi-document Summarization

Understand

We present PeerSum, a new MDS dataset using peer reviews of scientific publications.

• Our dataset differs from the existing MDS datasets in that our summaries (i.e., the meta-reviews) are highly abstractive and they are real summaries of the source documents (i.e., the reviews) and it also features disagreements among source documents.
• We found that current state-of-the-art MDS models struggle to generate high-quality summaries for PeerSum, offering new research opportunities.
