The Visual Question Answering (VQA) task aspires to provide a meaningful testbed for the development of AI models that can jointly reason over visual and natural language inputs. Despite a proliferation of VQA datasets, this goal is hindered by a set of common limitations. These include a reliance on relatively simplistic questions that are repetitive in both concepts and linguistic structure, little world knowledge needed outside of the paired image, and limited reasoning required to arrive at the correct answer. We introduce A-OKVQA, a crowdsourced dataset composed of a diverse set of about 25K questions requiring a broad base of commonsense and world knowledge to answer. In contrast to the existing knowledge-based VQA datasets, the questions generally cannot be answered by simply querying a knowledge base, and instead require some form of commonsense reasoning about the scene depicted in the image. We demonstrate the potential of this new dataset through a detailed analysis of its contents and baseline performance measurements over a variety of state-of-the-art vision-language models.

介绍了 A-OKVQA 数据集，它包含了约 25000 个多样化的问题，需要广泛的常识和世界知识才能回答，相对于现有的基于知识的 VQA 数据集，这些问题通常不能通过简单地查询知识库来回答，而是需要对图像中所描绘的场景进行某种形式的常识推理，该数据集对几种最先进的视觉语言模型进行了基础性能测试。
