Insert or Attach: Taxonomy Completion via Box Embedding (2024.acl-long)
Copied to clipboard
| Challenge: | Existing taxonomy expansion methods embed concepts as vectors in Euclidean space, causing incorrectly model asymmetric relations. |
| Approach: | They propose to use box containment and center closeness to create geometric scorers that capture intrinsic relationships between concepts. |
| Outcome: | The proposed framework outperforms existing methods on four real-world datasets. |
MProto: Multi-Prototype Network with Denoised Optimal Transport for Distantly Supervised Named Entity Recognition (2023.emnlp-main)
Copied to clipboard
| Challenge: | Distantly supervised named entity recognition (DS-NER) aims to locate entity mentions and classify their types with knowledge bases or gazetteers and unlabeled corpus. |
| Approach: | They propose a noise-robust prototype network named MProto for a DS-NER task . they propose an optimal transport algorithm to mitigate the noise from incomplete labeling . |
| Outcome: | The proposed network achieves state-of-the-art on several DS-NER benchmarks. |
