DSRAG: A Double-Stream Retrieval-Augmented Generation Framework for Countless Intent Detection

NAACL 2025industry

Current intent detection work experiments with minor intent categories. However, in real-world scenarios of data analysis dialogue systems, intents are composed of combinations of numerous metrics and dimensions, resulting in countless intents and posing challenges for the language model. The retrie…

Solid-SQL: Enhanced Schema-linking based In-context Learning for Robust Text-to-SQL

COLING 2025main

Recently, large language models (LLMs) have significantly improved the performance of text-to-SQL systems. Nevertheless, many state-of-the-art (SOTA) approaches have overlooked the critical aspect of system robustness. Our experiments reveal that while LLM-driven methods excel on standard datasets,…

Toward Structured Knowledge Reasoning: Contrastive Retrieval-Augmented Generation on Experience

ACL 2025finding

Large language models (LLMs) achieve strong performance on plain text tasks but underperform on structured data like tables and databases. Potential challenges arise from their underexposure during pre-training and rigid text-to-structure transfer mechanisms. Unlike humans who seamlessly apply learn…
