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.
