"I think, therefore I summarize"
Code and data accompanying the AAAI23 paper "Cogito Ergo Summ: Abstractive Summarization of Biomedical Papers via Semantic Parsing Graphs and Consistency Rewards".
CogitoErgoSumm is the first framework for single-document biomedical abstractive summarization equipping large pre-trained language models with rich domain-specific and domain-general semantic parsing graphs: events and AMRs. Event and AMR graph embeddings are learned by edge-aware graph attention networks. We propose new decoder cross-attention modules, and design a reinforcement learning (RL) reward signal to preserve source-summary semantics consistency.
Experiments and ablation studies on CDSR demonstrate that our framework sets new marks in informativeness, factuality, and readability, better selecting and preserving summary-worth content.
