Evaluating Vision-Language Models' Understanding of Compound Nouns

Q: How can vision-language models be further improved to better understand the semantic relationships between nouns in compound nouns?

Vision-language models can be enhanced to better understand the semantic relationships between nouns in compound nouns by incorporating several strategies: Fine-tuning with Compound Noun Data: Training vision-language models on a diverse dataset specifically focused on compound nouns can help them learn the nuanced relationships between the constituent nouns. This targeted training can improve the models' ability to interpret compound nouns accurately. Contextual Embeddings: Utilizing contextual embeddings can provide a deeper understanding of the relationships between words in compound nouns. Models like BERT or GPT, which capture contextual information, can enhance the semantic understanding of compound nouns. Multi-Modal Fusion: Integrating multiple modalities such as text and images more effectively can aid in capturing the complex relationships within compound nouns. Techniques like cross-modal attention mechanisms can help the model focus on relevant parts of the input. Knowledge Graph Integration: Incorporating knowledge graphs that represent semantic relationships between concepts can assist vision-language models in understanding the connections between nouns in compound nouns. This external knowledge can enrich the model's understanding of the semantic context. Adversarial Training: Adversarial training with perturbed compound nouns can help the model robustly learn the relationships between the constituent words. By exposing the model to challenging examples, it can improve its ability to interpret compound nouns accurately.

Q: How can the insights from this work on compound noun interpretation be applied to improve vision-language models' understanding of other types of compositional language, such as multi-word expressions or metaphors?

The insights gained from the study on compound noun interpretation can be extrapolated to enhance vision-language models' understanding of other forms of compositional language: Multi-Word Expressions: Similar to compound nouns, multi-word expressions involve multiple words combined to convey a specific meaning. By adapting the methodology used for compound nouns, models can be trained to decipher the semantic relationships within multi-word expressions. Metaphors: Metaphors often involve figurative language where words convey meanings beyond their literal interpretation. By training models on metaphorical expressions and providing contextual cues, vision-language models can learn to identify and interpret metaphors in text and images. Contextual Embeddings for Figurative Language: Leveraging contextual embeddings and pre-trained language models can aid in capturing the nuanced meanings of multi-word expressions and metaphors. Models can learn to associate words in these expressions based on the surrounding context, improving their comprehension of figurative language. Fine-Tuning with Diverse Data: Fine-tuning vision-language models on diverse datasets containing multi-word expressions and metaphors can expose the models to a wide range of linguistic constructs. This exposure can help the models generalize better to different types of compositional language. Semantic Role Labeling: Incorporating semantic role labeling techniques can assist in identifying the roles of words within multi-word expressions and metaphors. By understanding the semantic roles, models can better grasp the relationships between words and interpret the intended meaning accurately. By applying the lessons learned from compound noun interpretation to these forms of compositional language, vision-language models can advance their understanding of complex linguistic structures and improve their overall language comprehension capabilities.

Core Concepts

Open-vocabulary vision-language models like CLIP struggle to interpret compound nouns as effectively as they understand individual nouns, particularly when one noun acts as an attribute to the other.

Abstract

The paper presents a novel benchmark called Compun to evaluate the ability of vision-language models (VLMs) to interpret compound nouns (CNs). Compun consists of 400 unique and commonly used CNs, each with one image representing the CN and two distractor images showing the individual constituent nouns.

The key findings are:

VLMs like CLIP perform poorly on CNs where one noun acts as an attribute to the other, modifying the visual appearance minimally. CLIP makes the highest number of mistakes in this category, indicating its limited understanding of such "attributed" CNs.
CLIP performs better on CNs where both constituent nouns are clearly visible in the image, as well as on CNs that form a completely new visual concept not resembling either of the constituent nouns.
The authors propose a novel framework that goes beyond generic template-based prompts for text-to-image retrieval. It leverages a large language model to generate diverse captions describing scenes with the CN as a key object. This approach improves CLIP's and OpenCLIP's performance on Compun by 8.25% and 2.35%, respectively.
The authors also provide an in-depth analysis of CLIP's performance, showing that high accuracy on the Compun benchmark is often superficial, with CLIP winning by low similarity scores rather than true understanding.

"CLIP makes the highest number of mistakes in the first category, which also indicates CLIPs' limited understanding of such CNs, which can also be interpreted as attributed CNs."
"CLIP performs better on CNs where both constituent nouns are clearly visible in the image, as well as on CNs that form a completely new visual concept not resembling either of the constituent nouns."

Quotes

"Interpreting the meaning of CNs by decoding the implicit semantic relation between their constituent nouns has attracted great interest in Natural Language Processing (NLP) for decades."
"To the best of our knowledge, evaluating a VLM's understanding of the semantic relationship between nouns to interpret CNs hasn't been explored in literature."
