Data goes far beyond text—it is inherently multimodal, encompassing images, video, audio, and more, often in complex and unstructured formats. While the common method is to convert PDFs, scanned images, slides, and other documents into text, it is challenging to capture all information in text format, as shown in Figure 1. The loss of visual information in text motivated the development of…
