Structured RAG for Answering Aggregative Questions

arXiv — cs.LG•Wednesday, November 12, 2025 at 5:00:00 AM
PositiveArtificial Intelligence
The introduction of S-RAG marks a significant advancement in the field of question answering, particularly for aggregative queries that necessitate comprehensive information gathering from extensive document sets. Traditional RAG systems have struggled with such queries, often focusing on smaller, more specific segments of data. By creating a structured representation of the corpus at ingestion and translating queries into formal structures at inference, S-RAG enhances the ability to reason over large datasets. The validation of this approach is supported by the introduction of two new datasets, HOTELS and WORLD CUP, specifically designed for aggregative queries. Experiments have demonstrated that S-RAG outperforms both conventional RAG systems and long-context LLMs, indicating its potential to transform how complex questions are answered in AI applications.

Scaling Latent Reasoning via Looped Language Models
PositiveArtificial Intelligence
The article presents Ouro, a family of pre-trained Looped Language Models (LoopLM) designed to enhance reasoning capabilities during the pre-training phase. Unlike traditional models that rely on explicit text generation, Ouro incorporates iterative computation in latent space and an entropy-regularized objective for depth allocation. The models, Ouro 1.4B and 2.6B, demonstrate superior performance, matching results of larger state-of-the-art models while emphasizing improved knowledge manipulation rather than increased capacity.

Thinker: Training LLMs in Hierarchical Thinking for Deep Search via Multi-Turn Interaction
PositiveArtificial Intelligence
The article presents Thinker, a hierarchical thinking model designed to enhance the reasoning capabilities of large language models (LLMs) through multi-turn interactions. Unlike previous methods that relied on end-to-end reinforcement learning without supervision, Thinker allows for a more structured reasoning process by breaking down complex problems into manageable sub-problems. Each sub-problem is represented in both natural language and logical functions, improving the coherence and rigor of the reasoning process.

From Fact to Judgment: Investigating the Impact of Task Framing on LLM Conviction in Dialogue Systems
NeutralArtificial Intelligence
The article investigates the impact of task framing on the conviction of large language models (LLMs) in dialogue systems. It explores how LLMs assess tasks requiring social judgment, contrasting their performance on factual queries with conversational judgment tasks. The study reveals that reframing a task can significantly alter an LLM's judgment, particularly under conversational pressure, highlighting the complexities of LLM decision-making in social contexts.

Expert-Guided Prompting and Retrieval-Augmented Generation for Emergency Medical Service Question Answering
PositiveArtificial Intelligence
Large language models (LLMs) have shown potential in medical question answering but often lack the domain-specific expertise required in emergency medical services (EMS). The study introduces EMSQA, a dataset with 24.3K questions across 10 clinical areas and 4 certification levels, along with knowledge bases containing 40K documents and 2M tokens. It also presents Expert-CoT and ExpertRAG, strategies that enhance performance by integrating clinical context, resulting in improved accuracy and exam pass rates for EMS certification.

Can LLMs Detect Their Own Hallucinations?
PositiveArtificial Intelligence
Large language models (LLMs) are capable of generating fluent responses but can sometimes produce inaccurate information, referred to as hallucinations. A recent study investigates whether these models can recognize their own inaccuracies. The research formulates hallucination detection as a classification task and introduces a framework utilizing Chain-of-Thought (CoT) to extract knowledge from LLM parameters. Experimental results show that GPT-3.5 Turbo with CoT detected 58.2% of its own hallucinations, suggesting that LLMs can identify inaccuracies if they possess sufficient knowledge.
