Multi-modal Contrastive Representation Learning for Entity Alignment (2022.coling-1)
Copied to clipboard
| Challenge: | Existing studies focus on how to utilize information from different modalities, but it is not trivial to leverage multi-modal knowledge in entity alignment because of the modality heterogeneity. |
