| Challenge: | Existing methods to embed knowledge bases into large pre-training models do not contain any explicit grounding to real world entities and are difficult to recover factual knowledge. |
| Approach: | They propose a method to embed multiple knowledge bases (KBs) into large pretrained models with a Knowledge Attention and Recontextualization mechanism. |
| Outcome: | The proposed model improves perplexity, ability to recall facts and word sense disambiguation. |
