UETrice at MEDIQA 2021: A Prosper-thy-neighbour Extractive Multi-document Summarization Model

摘要

This paper describes a system developed to summarize multiple answers challenge in the MEDIQA 2021 shared task collocated with the BioNLP 2021 Workshop. We propose an extractive summarization architecture based on several scores and state-of-the-art techniques. We also present our novel prosper-thy-neighbour (PtN) strategies to improve performance. Our mode! has been proven to be effective with the best ROUGE-1/ROUGE-L scores, being the shared task runner-up by ROUGE-2 F1 score (over 13 participated teams).
