Towards Artwork Explanation in Large-scale Vision Language Models
Proposes artwork explanation generation task; LVLMs face challenges in integrating language and visual information.
Key Findings
Methodology
The study introduces an artwork explanation generation task, developing a dataset of approximately 10,000 Wikipedia articles. The task is divided into two parts: generating explanations from images and titles, and from images alone. Evaluation metrics include BLEU, ROUGE, BERTScore, and entity coverage.
Key Results
- With titles, GPT-4-Vision achieved the best performance in entity coverage and F1 metrics, while Qwen-VL-Chat (FT) excelled in entity cooccurrence precision.
- Without titles, Qwen-VL-Chat (FT) outperformed GPT-4-Vision across all metrics, demonstrating the dataset's effectiveness in visual information generation.
- Compared to LLMs, LVLMs show some knowledge retention loss, but Qwen-VL-Chat achieved a 10% performance boost in titled settings.
Significance
This research fills a gap in LVLMs' ability to generate artwork explanations by proposing a new task and dataset. It provides a new perspective for evaluating models' ability to integrate complex knowledge and generate coherent explanations, significantly impacting academic and industry research on vision-language models.
Technical Contribution
Technical contributions include developing a new dataset and evaluation metrics, highlighting challenges in integrating visual and language information in LVLMs, and experimentally validating different models' performance in the artwork explanation generation task.
Novelty
This is the first task specifically targeting artwork explanation generation, providing a new dataset and evaluation framework that fills gaps in existing research on complex knowledge integration.
Limitations
- The dataset relies on Wikipedia, potentially leading to inconsistencies and biases.
- Models perform poorly when generating text based solely on visual information, relying heavily on text cues.
- No human evaluation was conducted, leaving the practical application of model-generated explanations unverified.
Future Work
Future research could explore better integration of visual and language information, possibly by introducing external knowledge bases or improving model architectures to enhance performance.
AI Executive Summary
In the field of vision-language models (LVLMs), existing models face significant challenges in generating explanations for artworks. Traditional tasks like visual question answering and image captioning primarily assess models' ability to handle isolated knowledge, failing to capture the complexity of knowledge integration.
This paper proposes a new task: artwork explanation generation, and develops a dataset of approximately 10,000 Wikipedia articles. The task is divided into two parts: generating explanations from images and titles, and from images alone, aiming to evaluate LVLMs' performance in integrating language and visual knowledge.
Experimental results show that while LVLMs face challenges in integrating language and visual information, the use of new datasets and evaluation metrics can better understand and improve models' knowledge integration capabilities. Future research could explore how to introduce external knowledge bases or improve model architectures to further enhance performance.
Deep Analysis
Background
Vision-language models (LVLMs) have made significant progress in recent years, combining large language models (LLMs) with visual encoders. However, existing tasks like visual question answering and image captioning primarily assess models' ability to handle isolated knowledge, failing to capture the complexity of knowledge integration. This limits LVLMs' performance in practical applications, especially in scenarios requiring the integration of multiple types of knowledge.
Core Problem
The core problem lies in how LVLMs can effectively integrate language and visual information when generating explanations for artworks. Existing models perform poorly in handling complex knowledge relationships and generating coherent explanations, especially when generating text based solely on images. Solving this problem is crucial for improving models' performance in practical applications.
Innovation
The core innovation of this paper is the proposal of an artwork explanation generation task, developing a new dataset and evaluation metrics. This task evaluates models' performance in integrating language and visual information, filling gaps in existing research. Unlike previous tasks, this task requires models to generate coherent explanations involving complex knowledge integration.

Experiments
Experiments used multiple LVLMs, including mPLUG-Owl2, LLaVA-NeXT, Qwen-VL-Chat, and GPT-4-Vision. The dataset was divided into training, development, and test sets, with the test set further divided into seen and unseen settings. Evaluation metrics included BLEU, ROUGE, BERTScore, and entity coverage.

With titles, GPT-4-Vision achieved the best performance in entity coverage and F1 metrics, while Qwen-VL-Chat (FT) excelled in entity cooccurrence precision. Without titles, Qwen-VL-Chat (FT) outperformed GPT-4-Vision across all metrics, demonstrating the dataset's effectiveness in visual information generation.
Applications
Applications of this research include automatic generation of artwork explanations, information integration in cultural heritage preservation, and dissemination of art knowledge in education. These applications can help enhance public understanding and appreciation of artworks.
Limitations & Outlook
The study's limitations include the dataset's reliance on Wikipedia, potentially leading to inconsistencies and biases. Additionally, models perform poorly when generating text based solely on visual information, relying heavily on text cues. Future research could explore better integration of visual and language information.

Abstract
Large-scale Vision-Language Models (LVLMs) output text from images and instructions, demonstrating capabilities in text generation and comprehension. However, it has not been clarified to what extent LVLMs possess the ability to understand the knowledge necessary for explaining images, the complex relationships between various pieces of knowledge, and how they integrate these understandings into their explanations. To address this issue, we propose a new task: the artwork explanation generation task, along with its evaluation dataset and metrics for quantitatively assessing the understanding and utilization of knowledge about artworks. This task is apt for image description based on the premise that LVLMs are expected to have pre-existing knowledge of artworks, which are often subjects of wide recognition and documented information. It consists of two parts: generating explanations from images and titles of artworks, and generating explanations using only images, thus evaluating the LVLMs' language-based and vision-based knowledge. Alongside, we release a training dataset for LVLMs to learn explanations that incorporate knowledge about artworks. Our findings indicate that LVLMs not only struggle with integrating language and visual information but also exhibit a more pronounced limitation in acquiring knowledge from images alone.
