SEQZERO: Few-shot Compositional Semantic Parsing with Sequential Prompts and Zero-shot Models (2022.findings-naacl)
Copied to clipboard
| Challenge: | Recent research shows promising results on combining pretrained language models with canonical utterance for few-shot semantic parsing. |
| Approach: | They propose a few-shot semantic parsing method that decomposes a problem into a sequence of sub-problems, which correspond to the sub-clauses of the formal language. |
| Outcome: | The proposed method achieves SOTA performance of BART-based models on GeoQuery and EcommerceQuery, which are two few-shot datasets with compositional data split. |
