Social Chain of Thought: A Multi-Agent Architecture Grounded in Medical Differential Diagnosis Methodology

Del Coburn, Scott Sanner, Dan Silver

Medical diagnostic reasoning is a high-impact use case for LLMs that carries significant implications for the health and wellbeing of users. When OpenAI (2026) reports that more th…

Evaluating Scene-based In-Situ Item Labeling for Immersive Conversational Recommendation

Jiazhou Liang, Yifan Simon Liu, David Guo +3

The growing ubiquity of Extended Reality (XR) is driving Conversational Recommendation Systems (CRS) toward visually immersive experiences. We formalize this paradigm as Immersive…

Goal-Oriented Reasoning for RAG-based Memory in Conversational Agentic LLM Systems

Jiazhou Liang, Armin Toroghi, Yifan Simon Liu +3

LLM-based conversational AI agents struggle to maintain coherent behavior over long horizons due to limited context. While RAG-based approaches are increasingly adopted to overcome…

Temporal Order Matters for Agentic Memory: Segment Trees for Long-Horizon Agents

Yifan Simon Liu, Liam Gallagher, Faeze Moradi Kalarde +3

Long-horizon conversational agents need to interact with users through evolving events, tasks, and goals. Such histories are naturally temporal, yet many existing memory systems or…

CommonWhy: A Dataset for Evaluating Entity-Based Causal Commonsense Reasoning in Large Language Models

Armin Toroghi, Faeze Moradi Kalarde, Scott Sanner

To effectively interact with the real world, Large Language Models (LLMs) require entity-based commonsense reasoning, a challenging task that necessitates integrating factual knowl…

Semantic XPath: Structured Agentic Memory Access for Conversational AI

Yifan Simon Liu, Ruifan Wu, Liam Gallagher +3

Conversational AI (ConvAI) agents increasingly maintain structured memory to support long-term, task-oriented interactions. In-context memory approaches append the growing history…
