Towards Machine Reading for Interventions from Humanitarian-Assistance Program Literature (D19-1)
Copied to clipboard
| Challenge: | a complex socio-political system is causing problems such as food insecurity . a first step is to extract past interventions and when and where they have been applied . |
| Approach: | They develop an automatic extraction system to extract past interventions from texts . they analyze a corpus annotated with interventions to foster research . |
| Outcome: | The proposed system extracts past interventions and when and where they have been applied from text . it shows early, encouraging results on extracting interventions . |
Rapid Customization for Event Extraction (P19-3)

| Challenge: | a novel system allows users to customize event extraction to find new event types and their arguments. |
| Approach: | They propose a system that allows a user to find, expand and filter event triggers by exploring an unannotated development corpus. |
| Outcome: | The proposed system can find, expand and filter event triggers from an unannotated development corpus . it trains a generic argument attachment model for extracting Actor, Place, and Time . |
Towards Few-Shot Event Mention Retrieval: An Evaluation Framework and A Siamese Network Approach (2020.lrec-1)
Copied to clipboard
| Challenge: | Existing methods for event extraction are "one size fits all" and are not adaptable to new event types or domains of interest. |
| Approach: | They propose a few-shot Event Mention Retrieval task to retrieve event mentions from text . they use existing event datasets such as ACE and a Siamese Network approach . |
| Outcome: | The proposed approach lowers the bar of specifying event-centric information needs. |
