We live in a connected world, where events taking place across the globe often have the power to impact our daily lives. Such events reach us and are broadcasted by us in the form of visual and textual content, generating a massive unstructured pool of data. A paramount example is a recent blaze that struck the Notre-Dame Cathedral, an ancient Parisian architectural and religious symbol. In April 2019, a fire tore through the cathedral, devastating large parts of its structure and spire (Figure 1). People worldwide followed the tragic event through millions of images and videos that were shared by the media and everyday citizens, at the same time that part of the structure turned to dust.
