Multi-view Contrastive Learning for Entity Typing over Knowledge Graphs (2023.emnlp-main)
Copied to clipboard
| Challenge: | Existing approaches to knowledge graph entity typing ignore the way types can be clustered together. |
| Approach: | They propose a method that effectively encodes coarse-grained knowledge from clusters into entity and type embeddings. |
| Outcome: | The proposed method encodes coarse-grained knowledge from clusters into entity and type embeddings. |
Transformer-based Entity Typing in Knowledge Graphs (2022.emnlp-main)
Copied to clipboard
| Challenge: | Existing knowledge graphs encoding entity types are far from complete, since in real-world applications they are continuously emerging. |
| Approach: | They propose a transformer-based approach to infer plausible entity types by encoding neighbours' information by a local transformer and a global transformer. |
| Outcome: | The proposed approach outperforms the state-of-the-art on two real-world datasets. |
