CMDR: Contextual Multimodal Document Retrieval

Ryota Tanaka, Taku Hasegawa, Kyosuke Nishida

Multimodal document retrieval aims to retrieve relevant pages while preserving both textual and visual content from the original document. However, existing benchmarks primarily ev…

Responses Fall Short of Understanding: Revealing the Gap between Internal Representations and Responses in Visual Document Understanding

Haruka Kawasaki, Ryota Tanaka, Kyosuke Nishida

Visual document understanding (VDU) is a challenging task for large vision language models (LVLMs), requiring the integration of visual perception, text recognition, and reasoning…

Nodes Are Early, Edges Are Late: Probing Diagram Representations in Large Vision-Language Models

Haruto Yoshida, Keito Kudo, Yoichi Aoki +4

Large vision-language models (LVLMs) demonstrate strong performance on diagram understanding benchmarks, yet they still struggle with understanding relationships between elements,…

Instruction-Following Evaluation of Large Vision-Language Models

Daiki Shiono, Shumpei Miyawaki, Ryota Tanaka +1

Following the initial flourishing of large language models (LLMs), there has been a surge in proposed large vision-language models (LVLMs) that integrate LLMs with vision capabilit…

VDocRAG: Retrieval-Augmented Generation over Visually-Rich Documents

Ryota Tanaka, Taichi Iki, Taku Hasegawa +3

We aim to develop a retrieval-augmented generation (RAG) framework that answers questions over a corpus of visually-rich documents presented in mixed modalities (e.g., charts, tabl…

Empirical Analysis of Large Vision-Language Models against Goal Hijacking via Visual Prompt Injection

Subaru Kimura, Ryota Tanaka, Shumpei Miyawaki +2

We explore visual prompt injection (VPI) that maliciously exploits the ability of large vision-language models (LVLMs) to follow instructions drawn onto the input image. We propose…

InstructDoc: A Dataset for Zero-Shot Generalization of Visual Document Understanding with Instructions

Ryota Tanaka, Taichi Iki, Kyosuke Nishida +2

We study the problem of completing various visual document understanding (VDU) tasks, e.g., question answering and information extraction, on real-world documents through human-wri…
