Papers with Knowledge graph embedding methods
A Relational Memory-based Embedding Model for Triple Classification and Search Personalization (2020.acl-main)
Copied to clipboard
| Challenge: | Existing knowledge graph embedding methods do not allow for the prediction of new triples, such as for search personalization tasks. |
| Approach: | They propose a relational memory network to encode potential dependencies in relationship triples by a transformer self-attention mechanism. |
| Outcome: | The proposed model obtains state-of-the-art results on SEARCH17, WN11 and FB13 for the search personalization task, and on a convolutional neural network-based decoder. |
TranSHER: Translating Knowledge Graph Embedding with Hyper-Ellipsoidal Restriction (2022.emnlp-main)
Copied to clipboard
| Challenge: | Existing knowledge graph embedding methods restrict entities on hyper-ellipsoid surfaces, resulting in suboptimal knowledge graph completion. |
| Approach: | They propose a score function that leverages relation-specific translations between head and tail entities to relax constraints on hyper-ellipsoid surfaces. |
| Outcome: | The proposed method achieves state-of-the-art performance on link prediction and generalizes well to datasets in different domains and scales. |
