DeltaScore: Fine-Grained Story Evaluation with Perturbations (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Existing evaluation metrics for stories are limited in assessing intricate aspects of storytelling, such as fluency and interestingness. |
| Approach: | They propose a novel method that uses perturbation techniques to evaluate story aspects . they compare fluency, coherence, relatedness, logicality, interestingness and interestingness to existing metrics . |
| Outcome: | The proposed method shows that one specific perturbation is highly effective in capturing multiple aspects. |

| Challenge: | Recent research has focused on identifying text that introduces new, previously unknown information, but has seen a decline in novelty detection due to the rise of large language models. |
| Approach: | They propose a novel automated metric for evaluating document-level novelty that aggregates the novelty and salience scores of atomic information and provides high interpretability and a detailed analysis of a document's novelty. |
| Outcome: | The proposed metric scores high on the TAP-DLND 1.0 dataset and a human-annotated dataset. |
