Dual Complex Number Knowledge Graph Embeddings (2024.lrec-main)
Copied to clipboard
| Challenge: | Existing knowledge graph embedding methods fail to model non-commutative composition patterns . extending to such sophisticated spaces increases the amount of parameters, which greatly reduces the parameter efficiency. |
| Approach: | They propose a new knowledge graph embedding method that maps entities to the dual complex number space and represents relations as rotations in 2D space via dual complex multiplication. |
| Outcome: | Experiments on multiple benchmark knowledge graphs show that the proposed method improves link prediction and path query answering. |
Perspective-driven Preference Optimization with Entropy Maximization for Diverse Argument Generation (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Argument generation with diverse perspectives is essential for fostering balanced discourse and mitigating bias. |
| Approach: | They propose a Perspective-aware Preference Optimization with Entropy Maximization framework for diverse argument generation. |
| Outcome: | The proposed framework enhances perspective diversity through preference optimization based on the constructed preference dataset . |
