Challenge: Existing methods for abstractive summarization generate factual consistency summaries with a high level of accuracy and coherence.
Approach: They propose a framework that induces the guidance information and generates summary equipment with the guidance synchronously.
Outcome: The proposed framework generates fluent summaries with no constraint on the words and phrases, and is more faithful than the existing state-of-the-art approaches.
