SPARROW: Scalable Taxonomy Induction via Structure-Preserving Partitioning and Constraint-Guided Merging

Yirui Zhang, Yixuan Tang, Yandong Sun +2

Taxonomy induction aims to organize concept sets into coherent hierarchical structures. Recent LLM-based methods can induce taxonomies directly from flat term lists, avoiding the n…

CDEG: Learning Decision-Critical Evidence for Long-Horizon Diagnostic Agents

Xiwei Dai, Zijie Meng, Zhiting Fan +4

Unlike static medical question answering, long-horizon diagnosis captures the sequential nature of clinical practice: evidence is progressively acquired, integrated, and evaluated…

A-TMA: Decoupling State-Aware Memory Failures in Long-Term Agent Memory

Zitong Shi, Yixuan Tang, Anthony Kum Hoe Tung

Long term memory lets LLM agents act as persistent assistants, but user facts change. A useful memory system must know what is true now, what used to be true, and what changed. We…

MPCG: Multi-Round Persona-Conditioned Generation for Modeling the Evolution of Misinformation with LLMs

Jun Rong Brian Chong, Yixuan Tang, Anthony K. H. Tung

Misinformation evolves as it spreads, shifting in language, framing, and moral emphasis to adapt to new audiences. However, current misinformation detection approaches implicitly a…

Do Multi-Hop Question Answering Systems Know How to Answer the Single-Hop Sub-Questions?

Yixuan Tang, Hwee Tou Ng, Anthony K. H. Tung

Multi-hop question answering (QA) requires a model to retrieve and integrate information from different parts of a long text to answer a question. Humans answer this kind of comple…
