A Novel Cascade Binary Tagging Framework for Relational Triple Extraction (2020.acl-main)
Copied to clipboard
| Challenge: | Existing approaches to extract relational triples from unstructured text are inadequate to solve the overlapping triple problem. |
| Approach: | They propose a cascade binary tagging framework that models relations as functions that map subjects to objects in a sentence. |
| Outcome: | The proposed framework outperforms state-of-the-art methods on two datasets . it outperformed baseline methods by 17.5 and 30.2 absolute gains . |
A Dataset for Hyper-Relational Extraction and a Cube-Filling Approach (2022.emnlp-main)
Copied to clipboard
| Challenge: | Existing methods do not consider qualifier attributes for each relation triplet, such as time, quantity or location. |
| Approach: | They propose a hyper-relational extraction task to extract more specific facts from text using qualifiers. |
| Outcome: | The proposed model outperforms baselines and reveal possible directions for future research. |
