Deep Analysis
Background
In the field of art understanding, multimodal large language models (MLLMs) have made significant strides in recent years. These models, by integrating visual encoders with large language models, have shown strong performance in tasks like image captioning and visual question answering. However, in the domain of art, these models often struggle to provide reliable and interpretable explanations, as their reasoning relies on implicit knowledge that may be incomplete or hallucinated. To address these issues, researchers have begun exploring retrieval-augmented generation (RAG) methods, which incorporate external knowledge during inference to improve factual grounding. However, most RAG systems adopt static, single-shot retrieval strategies, limiting their ability to support multi-step reasoning or adapt retrieval to different reasoning needs.
Core Problem
Understanding artworks requires moving beyond surface-level image descriptions to engage in multi-step reasoning. This involves recognizing visual elements, symbolic meanings, artistic styles, and cultural-historical contexts, integrating complex information. Existing multimodal large language models often struggle with these complex tasks, as their reasoning relies on implicit knowledge, lacking explicit evidence grounding. The core problem is how to introduce explicit reasoning plans into multimodal retrieval to support complex art understanding.

Imagine you're in a large museum, facing a complex artwork. You not only need to understand every detail in the painting but also the story, cultural background, and artistic style behind it. A-MAR acts like your personal guide, helping you break down the complex information in the painting and create a clear tour plan. Each step tells you what details to focus on, why they're important, and how they relate to the artwork's background. This way, you can not only appreciate the painting better but also understand its deeper meaning. A-MAR's uniqueness lies in its ability to draw not only from the painting itself but also from the museum's database to provide more background knowledge, helping you gain a comprehensive understanding of the artwork. Like an experienced guide, it pauses at each key point to explain the historical context and cultural stories, enriching your art appreciation with knowledge and inspiration.

Abstract
Understanding artworks requires multi-step reasoning over visual content and cultural, historical, and stylistic context. While recent multimodal large language models show promise in artwork explanation, they rely on implicit reasoning and internalized knowl- edge, limiting interpretability and explicit evidence grounding. We propose A-MAR, an Agent-based Multimodal Art Retrieval framework that explicitly conditions retrieval on structured reasoning plans. Given an artwork and a user query, A-MAR first decomposes the task into a structured reasoning plan that specifies the goals and evidence requirements for each step. Retrieval is then conditionedon this plan, enabling targeted evidence selection and supporting step-wise, grounded explanations. To evaluate agent-based multi- modal reasoning within the art domain, we introduce ArtCoT-QA. This diagnostic benchmark features multi-step reasoning chains for diverse art-related queries, enabling a granular analysis that extends beyond simple final answer accuracy. Experiments on SemArt and Artpedia show that A-MAR consistently outperforms static, non planned retrieval and strong MLLM baselines in final explanation quality, while evaluations on ArtCoT-QA further demonstrate its advantages in evidence grounding and multi-step reasoning ability. These results highlight the importance of reasoning-conditioned retrieval for knowledge-intensive multimodal understanding and position A-MAR as a step toward interpretable, goal-driven AI systems, with particular relevance to cultural industries.
