Low-Hallucination and Efficient Coreference Resolution with LLMs (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Large Language Models have shown promising results in coreference resolution, but they face a critical issue: hallucinations. |
| Approach: | They propose a low-hallucination and efficient solution to the problem of hallucinations . they propose efficient constrained decoding for coreference resolution . |
| Outcome: | The proposed approach achieves better performance on the English OntoNotes development set. |

| Challenge: | Existing text-to-SQL models rely on lexical matching between words in NL questions and tokens in table schemas, which may break the schema linking mechanism. |
| Approach: | They propose a human-curated dataset for text-to-SQL translation . they replace schema-related words with manually selected synonyms . |
| Outcome: | The proposed model outperforms its counterparts without the defense. |
Natural SQL: Making SQL Easier to Infer from Natural Language Specifications (2021.findings-emnlp)
Copied to clipboard
| Challenge: | Existing models that do not support executable SQL generation can generate executable queries. |
| Approach: | They propose an SQL intermediate representation called Natural SQL (NatSQL) they propose to preserve the core functionalities of SQL while simplifying the queries . |
| Outcome: | The proposed model outperforms existing models on a text-to-SQL benchmark . it significantly improves the performance of previous models on the same dataset . |
