CANarEx: Contextually Aware Narrative Extraction for Semantically Rich Text-as-data Applications (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Narrative modelling is a field of active research that conceptualizes narratives as connected entity chains. |
| Approach: | They propose an alternative narrative extraction approach using semantic role labeling to extract tuples from text, then dimensionality reduction to reduce the space of entities and connections separately. |
| Outcome: | The proposed approach improves on a text-as-data task and improves accuracy and recall. |
Models Teaching Models: Improving Model Accuracy with Slingshot Learning (2023.eacl-main)
Copied to clipboard
| Challenge: | Existing methods to label datasets are expensive and require human labor . a semi-supervised method that augments a small dataset with labels reduces the cost of using simpler methods . |
| Approach: | They propose a semi-supervised method to augment a human-labeled dataset with labels from a teacher model to slingshot the performance of a student model. |
| Outcome: | The proposed method reduces the accuracy trade-off required to use simpler methods without disrupting their benefits. |
