Exploring Explainable Selection to Control Abstract Generation
Table 6: Controllability: ROUGE Recall scores on the CNN/DailyMail dataset regarding different explainable aspects under different thresholds, such as novelty ϵn and relevance ϵr.
['[BOLD] Models ESCA', '[BOLD] R-1', '[BOLD] R-2', '[BOLD] R-L']
We evaluated the controlled performance by ROUGE recall because it shows whether additional relevant summaries can be included under the deterministic controls. Additionally, there is always a trade-off between controllability and summary performance since the gold summary was automatically constructed with bias and not based on these controllability properties.
