Code-Switching Reveals Language Anchoring in Multilingual LLMs

Jeonghyun Park, Seunghyun Yoon, Yonghyun Jun +1

Multilingual Large Language Models (MLLMs) are increasingly expected to handle Code-Switched (CS) inputs, yet mixing languages frequently degrades performance relative to source- o…

Beyond One Path: Evaluating and Enhancing Divergent Thinking in Interactive LLM Agents

Jihyeong Park, Ingeol Baek, Jeonghyun Park +1

Divergent thinking is a core dimension of creativity, yet existing evaluations of Large Language Models (LLMs) treat them as single-turn text generations, failing to capture how an…

Framing Matters: Addressing Framing Sensitivity in Decision-Making through Behaviorally-Grounded Value Alignment

Seojin Hwang, Minju Kim, Junhyuk Choi +2

Large Language Models (LLMs) are increasingly deployed in high-stakes decision-making settings such as legal reasoning, where consistency under factually equivalent inputs is criti…

Enhancing Multilingual RAG Systems with Debiased Language Preference-Guided Query Fusion

Jeonghyun Park, Byeongjeong Kim, Seojin Hwang +1

Multilingual Retrieval-Augmented Generation (mRAG) systems often exhibit a perceived preference for high-resource languages, particularly English, resulting in the widespread adopt…

MARCH: Evaluating the Intersection of Ambiguity Interpretation and Multi-hop Inference

Jeonghyun Park, Ingeol Baek, Seunghyun Yoon +5

Real-world multi-hop QA is naturally linked with ambiguity, where a single query can trigger multiple reasoning paths that require independent resolution. Since ambiguity can occur…

Investigating Language Preference of Multilingual RAG Systems

Jeonghyun Park, Hwanhee Lee

Multilingual Retrieval-Augmented Generation (mRAG) systems enhance language models by integrating external multilingual information to produce context-aware responses. However, mRA…

Hierarchical Visual Feature Aggregation for OCR-Free Document Understanding

Jaeyoo Park, Jin Young Choi, Jeonghyung Park +1

We present a novel OCR-free document understanding framework based on pretrained Multimodal Large Language Models (MLLMs). Our approach employs multi-scale visual features to effec…

Conversational Query Reformulation with the Guidance of Retrieved Documents

Jeonghyun Park, Hwanhee Lee

Conversational search seeks to retrieve relevant passages for the given questions in conversational question answering. Conversational Query Reformulation (CQR) improves conversati…
