CORAL: Benchmarking Multi-turn Conversational Retrieval-Augmented Generation

NAACL 2025findings

Retrieval-Augmented Generation (RAG) has become a powerful paradigm for enhancing large language models (LLMs) through external knowledge retrieval. Despite its widespread attention, existing academic research predominantly focuses on single-turn RAG, leaving a significant gap in addressing the comp…

Hierarchical Document Refinement for Long-context Retrieval-augmented Generation

ACL 2025long

Real-world RAG applications often encounter long-context input scenarios, where redundant information and noise results in higher inference costs and reduced performance. To address these challenges, we propose LongRefiner, an efficient plug-and-play refiner that leverages the inherent structural ch…

Neuro-Symbolic Query Compiler

ACL 2025finding

Precise recognition of search intent in Retrieval-Augmented Generation (RAG) systems remains a challenging goal, especially under resource constraints and for complex queries with nested structures and dependencies. This paper presents **QCompiler**, a neuro-symbolic framework inspired by linguistic…

RetroLLM: Empowering Large Language Models to Retrieve Fine-grained Evidence within Generation

ACL 2025long

Large language models (LLMs) exhibit remarkable generative capabilities but often suffer from hallucinations. Retrieval-augmented generation (RAG) offers an effective solution by incorporating external knowledge, but existing methods still face several limitations: additional deployment costs of sep…

WebThinker: Empowering Large Reasoning Models with Deep Research Capability

NeurIPS 2025poster

Large reasoning models (LRMs), such as OpenAI-o1 and DeepSeek-R1, demonstrate impressive long-horizon reasoning capabilities. However, their reliance on static internal knowledge limits their performance on complex, knowledge-intensive tasks and hinders their ability to produce comprehensive researc…

Zero-Shot Continuous Prompt Transfer: Generalizing Task Semantics Across Language Models

ICLR 2024poster

Prompt tuning in natural language processing (NLP) has become an increasingly popular method for adapting large language models to specific tasks. However, the transferability of these prompts, especially continuous prompts, between different models remains a challenge. In this work, we propose a ze…

Hence, Socrates is mortal: A Benchmark for Natural Language Syllogistic Reasoning

ACL 2023findings

Syllogistic reasoning, a typical form of deductive reasoning, is a critical capability widely required in natural language understanding tasks, such as text entailment and question answering. To better facilitate research on syllogistic reasoning, we develop a benchmark called SylloBase that differs…

IAG: Induction-Augmented Generation Framework for Answering Reasoning Questions

EMNLP 2023long main

Retrieval-Augmented Generation (RAG), by incorporating external knowledge with parametric memory of language models, has become the state-of-the-art architecture for open-domain QA tasks. However, common knowledge bases are inherently constrained by limited coverage and noisy information, making ret…

Coarse-to-Fine: Hierarchical Multi-task Learning for Natural Language Understanding

COLING 2022main

Generalized text representations are the foundation of many natural language understanding tasks. To fully utilize the different corpus, it is inevitable that models need to understand the relevance among them. However, many methods ignore the relevance and adopt a single-channel model (a coarse par…
