Measuring and Improving Compositional Generalization in Text-to-SQL via Component Alignment

1 code implementation Findings (NAACL) 2022 Yujian Gan, Xinyun Chen, Qiuping Huang, Matthew Purver

To deal with this problem, we modify a number of state-of-the-art models to train on the segmented data of Spider-SS, and we show that this method improves the generalization performance.

Exploring Underexplored Limitations of Cross-Domain Text-to-SQL Generalization

1 code implementation EMNLP 2021 Yujian Gan, Xinyun Chen, Matthew Purver

Recently, there has been significant progress in studying neural networks for translating text descriptions into SQL queries under the zero-shot cross-domain setting.

Natural SQL: Making SQL Easier to Infer from Natural Language Specifications

3 code implementations Findings (EMNLP) 2021 Yujian Gan, Xinyun Chen, Jinxia Xie, Matthew Purver, John R. Woodward, John Drake, Qiaofu Zhang

Addressing the mismatch between natural language descriptions and the corresponding SQL queries is a key challenge for text-to-SQL translation.

Towards Robustness of Text-to-SQL Models against Synonym Substitution

1 code implementation ACL 2021 Yujian Gan, Xinyun Chen, Qiuping Huang, Matthew Purver, John R. Woodward, Jinxia Xie, Pengsheng Huang

We observe that the accuracy dramatically drops by eliminating such explicit correspondence between NL questions and table schemas, even if the synonyms are not adversarially selected to conduct worst-case adversarial attacks.
