Adaptive Ordered Information Extraction with Deep Reinforcement Learning (2023.findings-acl)
Copied to clipboard
| Challenge: | Existing methods for information extraction follow a fixed extraction order for complex tasks with multiple elements to be extracted in one instance. |
| Approach: | They propose an adaptive ordered IE paradigm to find optimal element extraction order for different instances and a reinforcement learning framework to generate optimal order dynamically. |
| Outcome: | The proposed method beats existing methods and improves on several public datasets. |

| Challenge: | Adapting existing approaches for converting natural language to SQL encounters hurdles due to distinct nature of GQL compared to SQL. |
| Approach: | They propose a method that integrates both small and large Foundation Models for ranking, rewriting, and refining tasks. |
| Outcome: | The proposed approach integrates both small and large Foundation Models for ranking, rewriting, and refining tasks while capitalizing on the superior generalization and query generation prowess of larger models for the final transformation of natural language queries into GQL formats. |
