| Challenge: | Recent approaches to semantic parsing have cast it as a sequence-to-sequence task, with strong results. |
| Approach: | They propose a Graph Neural Network architecture to incorporate information about relevant entities and their relations during parsing. |
| Outcome: | The proposed approach outperforms the state-of-the-art in several tasks without pre-training and outperformed existing approaches when combined with BERT pre-trainment. |

Representing Schema Structure with Graph Neural Networks for Text-to-SQL Parsing (P19-1)
Copied to clipboard
| Challenge: | Semantic parsing to SQL has largely ignored the structure of the database schema . a recent study used a simple DB that was observed at both training and test time. |
| Approach: | They propose a semantic parser where the schema structure is encoded with a graph neural network and used at both encoding and decoding time. |
| Outcome: | The proposed parser improves from 33.8% to 39.4%, dramatically above the current state of the art, which is at 19.7%. |
