 PopVQA was curated to explore the disparity in model performance when answering factual questions about an entity described in text versus depicted in an image. This is achieved by asking the same questions twice, once with the textual representation (the entity's name), then, with the visual representation (entity image). We include several questions about every entity to allow a more fine grained evaluation.
