| Challenge: | Existing prompt engineering methods require labeled data and access to model parameters . a new method for selecting prompt templates without labeles and without direct access to the model is needed. |
| Approach: | They propose a method for selecting prompt templates without labeled examples and without direct access to the model. |
| Outcome: | The proposed method performs at almost oracle levels, without labels, on 7 datasets representing 7 different NLP tasks. |
The PGNSC Benchmark: How Do We Predict Where Information Spreads? (2024.findings-acl)
Copied to clipboard
| Challenge: | Social networks have become ideal vehicles for news dissemination because posted content is easily able to reach users beyond a news outlet’s direct audience. |
| Approach: | They propose a benchmark that builds information pathways based on the audiences of influential news sources and uses their content to characterize the communities. |
| Outcome: | The proposed benchmark builds information pathways based on the audiences of influential news sources and uses their content to characterize the communities. |
DICE: Data-Efficient Clinical Event Extraction with Generative Models (2023.acl-long)
Copied to clipboard
| Challenge: | EE tasks target specific domains with vague entity boundaries, resulting in a lack of training data. |
| Approach: | They propose a robust and data-efficient generative model for clinical event extraction . they frame event extraction as a conditional generation problem and introduce a contrastive learning objective to decide the boundaries of biomedical mentions. |
| Outcome: | The proposed model is robust and data-efficient for clinical event extraction . it trains an auxiliary mention identification task and event extraction tasks to better identify entity mention boundaries . |
