Multi-Input Multi-Output Sequence Labeling for Joint Extraction of Fact and Condition Tuples from Scientific Text (D19-1)
Copied to clipboard
| Challenge: | Existing methods to extract factual tuples from scientific text do not consider conditions. |
| Approach: | They propose a new sequence labeling framework to jointly extract fact and condition tuples from scientific sentences. |
| Outcome: | The proposed framework improves F1 score relative to existing methods by 4.2% and 6.2% on bioNLP2013. |
Few-Shot Multi-Hop Relation Reasoning over Knowledge Bases (2020.findings-emnlp)
Copied to clipboard
| Challenge: | Existing methods for multi-hop relation reasoning require limited data for each query relation, resulting in limited interpretation. |
| Approach: | They propose a few-shot multi-hop relation learning model that uses reinforcement learning to model sequential steps of multi-hopping reasoning and performs heterogeneous structure encoding and knowledge-aware search space pruning. |
| Outcome: | Empirical results show that the proposed model outperforms state-of-the-art models over few-shot relations. |
