A Vision-Language Model for Efficient Mobile GUI Search and Retrieval

Concepts de base

A novel vision-language model called UIClip that outperforms existing text-only and CLIP-based approaches in retrieving relevant mobile GUI screenshots from a large repository using textual queries.

Résumé

The paper proposes GUing, a GUI search engine based on a vision-language model called UIClip, which is trained on a large dataset of mobile app screenshots and captions.

Key highlights:

• The authors created two large datasets - GPSRepo (303k screenshots) and GPSCap (135k screenshot-caption pairs) - by mining app introduction images from Google Play.
• They fine-tuned the CLIP model on the GPSCap dataset to create UIClip, a vision-language model tailored for the GUI domain.
• Evaluation shows that UIClip outperforms text-only and generic CLIP-based approaches in text-to-GUI retrieval tasks, achieving a Recall@10 of up to 0.69 and a HIT@10 of 0.91.
• The GUing search engine, built on top of UIClip and the GUI repository, delivers highly relevant search results compared to baseline approaches.
• The authors also explore the performance of UIClip on other GUI-related tasks like sketch-to-GUI retrieval and GUI classification.

"Recent Vision-Language Models (VLMs), such as CLIP [49], BLIP [34], and BLIP-2 [33], are trained in large-scale image-caption data by contrastive learning. These models have the ability to transform images and text into a multimodal embedding, ensuring that semantically similar images and texts are mapped closely in the embedding space."
"By leveraging the GPSCap, in conjunction with Screen2Words and Clarity datasets, we fine tuned the CLIP model to create a VLM specific to the GUI domain. We call the new model UIClip."

Questions plus approfondies

How can the UIClip model be further improved to handle more complex and diverse GUI elements beyond screenshots, such as wireframes or sketches?

The UIClip model can be enhanced to handle more complex and diverse GUI elements by incorporating additional training data that includes wireframes and sketches. By expanding the dataset to include a variety of GUI representations, the model can learn to extract features and patterns from different types of visual elements. Additionally, fine-tuning the model on datasets specifically focused on wireframes and sketches can help UIClip better understand the unique characteristics and structures of these elements. Furthermore, incorporating domain-specific knowledge and features related to wireframes and sketches into the training process can improve the model's ability to accurately retrieve and interpret such GUI elements.

What are the potential limitations of the current approach in handling multilingual captions or supporting non-English text-to-GUI retrieval?

One potential limitation of the current approach in handling multilingual captions is the reliance on language-specific models and datasets. If the UIClip model is primarily trained on English text, it may struggle to accurately process and interpret captions in other languages. This limitation can lead to challenges in supporting non-English text-to-GUI retrieval, as the model may not effectively capture the nuances and context of different languages. Additionally, the performance of the model in multilingual scenarios may be impacted by the availability and quality of training data in various languages. Without sufficient multilingual training data, the model may struggle to generalize effectively across different languages and may exhibit biases or inaccuracies in non-English text-to-GUI retrieval tasks.

Could the UIClip model be extended to enable interactive GUI design by combining text-to-GUI retrieval with other GUI-related tasks like layout generation or component recommendation?

Yes, the UIClip model can be extended to enable interactive GUI design by integrating text-to-GUI retrieval with other GUI-related tasks such as layout generation and component recommendation. By incorporating additional modules or components that focus on layout generation and component recommendation, the UIClip model can offer a more comprehensive solution for interactive GUI design. For example, the model can be trained to understand the relationships between text descriptions and specific layout structures, allowing it to suggest appropriate design layouts based on the input text. Similarly, by incorporating knowledge about common GUI components and their functionalities, the model can recommend relevant components based on the text input, facilitating the design process for app developers and designers. This integration of text-to-GUI retrieval with layout generation and component recommendation can enhance the overall usability and effectiveness of the UIClip model for interactive GUI design tasks.
