| Challenge: | Existing datasets do not cover documents with complex spatial structures and a lack of spatial information for document entity classification. |
| Approach: | They propose a new spatial bias in attention calculation based on the K-nearest-neighbor graph of document entities that limits entities’ attention to their local radius. |
| Outcome: | The proposed model outperforms baselines in most entity types and is highly parameter-efficient compared to existing methods. |
