A Survey of RAG-Reasoning Systems in Large Language Models

EMNLP 2025

Retrieval-Augmented Generation (RAG) lifts the factuality of Large Language Models (LLMs) by injecting external knowledge, yet it falls short on problems that demand multi-step inference; conversely, purely reasoning-oriented approaches often hallucinate or mis-ground facts. This survey synthesizes

InteGround: On the Evaluation of Verification and Retrieval Planning in Integrative Grounding

EMNLP 2025

Grounding large language models (LLMs) in external knowledge sources is a promising method for faithful prediction. While existing grounding approaches work well for simple queries, many real-world information needs require synthesizing multiple pieces of evidence. We introduce “integrative groundin

Simulate and Eliminate: Revoke Backdoors for Generative Large Language Models

AAAI 2025technical

With rapid advances, generative large language models (LLMs) dominate various Natural Language Processing (NLP) tasks from understanding to reasoning. Yet, language models' inherent vulnerabilities may be exacerbated due to increased accessibility and unrestricted model training on massive data. A m…

CANDLE: Iterative Conceptualization and Instantiation Distillation from Large Language Models for Commonsense Reasoning

ACL 2024long

The sequential process of conceptualization and instantiation is essential to generalizable commonsense reasoning as it allows the application of existing knowledge to unfamiliar scenarios. However, existing works tend to undervalue the step of instantiation and heavilyrely on pre-built concept taxo…

ECON: On the Detection and Resolution of Evidence Conflicts

EMNLP 2024main

The rise of large language models (LLMs) has significantly influenced the quality of information in decision-making systems, leading to the prevalence of AI-generated content and challenges in detecting misinformation and managing conflicting information, or “inter-evidence conflicts.” This study in…

EventGround: Narrative Reasoning by Grounding to Eventuality-centric Knowledge Graphs

COLING 2024main

Narrative reasoning relies on the understanding of eventualities in story contexts, which requires a wealth of background world knowledge. To help machines leverage such knowledge, existing solutions can be categorized into two groups. Some focus on implicitly modeling eventuality knowledge by pretr…

NegotiationToM: A Benchmark for Stress-testing Machine Theory of Mind on Negotiation Surrounding

EMNLP 2024finding

Large Language Models (LLMs) have sparked substantial interest and debate concerning their potential emergence of Theory of Mind (ToM) ability. Theory of mind evaluations currently focuses on testing models using machine-generated data or game settings prone to shortcuts and spurious correlations, w…

PrivLM-Bench: A Multi-level Privacy Evaluation Benchmark for Language Models

ACL 2024long

The rapid development of language models (LMs) brings unprecedented accessibility and usage for both models and users. On the one hand, powerful LMs achieve state-of-the-art performance over numerous downstream NLP tasks. On the other hand, more and more attention is paid to unrestricted model acces…

Text-Tuple-Table: Towards Information Integration in Text-to-Table Generation via Global Tuple Extraction

EMNLP 2024main

The task of condensing large chunks of textual information into concise and structured tables has gained attention recently due to the emergence of Large Language Models (LLMs) and their potential benefit for downstream tasks, such as text summarization and text mining. Previous approaches often gen…

DiscoPrompt: Path Prediction Prompt Tuning for Implicit Discourse Relation Recognition

ACL 2023findings

Implicit Discourse Relation Recognition (IDRR) is a sophisticated and challenging task to recognize the discourse relations between the arguments with the absence of discourse connectives. The sense labels for each discourse relation follow a hierarchical classification scheme in the annotation proc…

Lion: Adversarial Distillation of Proprietary Large Language Models

EMNLP 2023long main

The practice of transferring knowledge from a sophisticated, proprietary large language model (LLM) to a compact, open-source LLM has garnered considerable attention. Previous works have focused on a unidirectional knowledge distillation way by aligning the responses of the student model with those…

StoryAnalogy: Deriving Story-level Analogies from Large Language Models to Unlock Analogical Understanding

EMNLP 2023long main

Analogy-making between narratives is crucial for human reasoning. In this paper, we evaluate the ability to identify and generate analogies by constructing a first-of-its-kind large-scale story-level analogy corpus, \textsc{StoryAnalogy}, which contains 24K story pairs from diverse domains with huma…
