Multimodal Dataset and Benchmark for Implicit Attribute Value Extraction


Core Concepts
The authors present ImplicitAVE, the first publicly available multimodal dataset for implicit attribute value extraction, and establish a comprehensive benchmark for evaluating multimodal large language models on this task.
Abstract
The authors present ImplicitAVE, a new multimodal dataset for implicit attribute value extraction (AVE). Existing AVE datasets predominantly focus on explicit attribute values and lack product images, are often not publicly available, and lack human inspection across diverse domains. To address these limitations, the authors: Curated and expanded the MAVE dataset to create ImplicitAVE, a refined dataset of 68k training and 1.6k testing instances across five domains, 25 attributes, and 158 attribute values, with a focus on implicit AVE and multimodality. Established a comprehensive benchmark for evaluating multimodal large language models (MLLMs) on the ImplicitAVE dataset, covering six recent MLLMs with 11 variants. The results reveal that implicit value extraction remains a challenging task for open-source MLLMs. Conducted in-depth analysis on the domain-level and attribute-level performance of the evaluated models, identifying key challenges and opportunities for future research. The authors found that the Clothing domain and attributes like Sleeve Style and Neckline are the most challenging for the evaluated models. They also observed that while GPT-4V outperformed other models, open-source MLLMs still lag behind in many domains and attributes, providing opportunities for further research.
Stats
"Implicit values can only be inferred from the product image, contextual clues, or prior knowledge." "Our dataset covers 5 diverse domains and 25 carefully curated attributes specially for the task of implicit attribute value extraction." "We have a total of 158 diverse attribute values."
Quotes
"Existing datasets for attribute value extraction exhibit several key limitations: (1) They predominantly focus on explicit attribute values, neglecting implicit attribute values (Zheng et al., 2018; Wang et al., 2020), which are more challenging and commonly encountered in real-world scenarios; (2) Many datasets lack product images (Yan et al., 2021; Yang et al., 2022), limiting their applicability in multimodal contexts; (3) The limited number of publicly available datasets lack human inspection and cover only a few domains, resulting in inaccurate and restricted benchmarks (Xu et al., 2019; Zhang et al., 2023)." "GPT-4V outperformed every other model in both the zero-shot and fine-tune setting in every single domain." "Among the open-source MLLMs, no single model outperformed all other models across all the domains, but Qwen-VL had the best scores in the Jewelry&GA and Food domains."

How can the performance of open-source MLLMs on the ImplicitAVE dataset be further improved, and what are the key challenges that need to be addressed

To improve the performance of open-source MLLMs on the ImplicitAVE dataset, several strategies can be implemented: Fine-Tuning: Fine-tuning the pre-trained models on the ImplicitAVE dataset can help the models adapt to the specific task of implicit attribute value extraction and improve their performance. Data Augmentation: Increasing the diversity and quantity of training data through data augmentation techniques can help the models learn more robust representations and improve generalization. Multimodal Fusion: Enhancing the integration of text and image modalities in the models can improve their ability to extract implicit attribute values by effectively leveraging information from both modalities. Prompt Engineering: Optimizing the prompts used for model inference can significantly impact performance. Experimenting with different prompt structures and content can lead to better results. Model Architecture: Exploring and modifying the architecture of the MLLMs to better capture the nuances of implicit attribute values and improve their understanding of multimodal inputs. Key challenges that need to be addressed include: Handling Ambiguity: Dealing with ambiguous or overlapping attribute values that may lead to confusion for the models. Domain Adaptation: Ensuring that the models can generalize well across different domains and adapt to new domains effectively. Data Quality: Ensuring the quality and accuracy of the training data, especially in the presence of implicit attribute values that may be more challenging to annotate. Interpretable Models: Developing models that not only perform well but also provide insights into their decision-making process, especially in complex multimodal scenarios.
