Leveraging Explicit Lexico-logical Alignments in Text-to-SQL Parsing (2022.acl-short)
Copied to clipboard
| Challenge: | Text-to-SQL parsing aims to parse natural language questions into SQL queries . current attention-based approaches can only model alignments at the token level . |
| Approach: | They propose a method to leverage explicit lexico-logical alignments by identifying possible phrase-level alignments and injecting them as additional contexts into the parsing procedure. |
| Outcome: | The proposed approach improves performance by 3.4% on Squall. |
A Compare Aggregate Transformer for Understanding Document-grounded Dialogue (2020.findings-emnlp)
Copied to clipboard
| Challenge: | Existing studies have focused on KS in unstructured documents, but dialogue history that is not related to the current dialogue may introduce noise in the KS processing. |
| Approach: | They propose a Compare Aggregate Transformer to jointly denoise the dialogue context and aggregate the document information for response generation. |
| Outcome: | The proposed model outperforms the state-of-the-art approach and strong baselines on a CMU_DoG dataset. |
