摘要:

从图像中生成自然、多样和有意义的问题是多模态助理的一项重要任务,因为它可以确认他们是否正确理解了图像中的对象和场景。可视化问答和可视化问题生成的研究是一个很大的进步。然而,这项研究并没有捕捉到视觉能力正常的人会问多模态助手的问题。最近发布的数据集,如KB-VQA,FVQA和OK-VQA,试图收集问题,寻找外部知识,使它们适合多模态助理。然而,它们仍然包含许多人类通常不会问数字助理的明显和常识性问题。在本文中,我们提供了一个新的基准数据集,其中包含由人类注释者生成的问题,并记住他们会向多模态数字助理提出什么问题。几十万幅图像的大规模注释是昂贵和耗时的,所以我们也提出了一种有效的方法,自动生成问题,从看不见的图像。在本文中,我们提出了一种方法,用于生成考虑图像内容和图像元数据(例如,位置、关联关键字)。我们使用BLEU、METEOR、ROUGE和CIDER等标准评估指标来评估我们的方法,以显示生成的问题与人类提供的问题的相关性。我们还使用生成强度和创造性指标来衡量生成问题的多样性。我们报告关于公众和我们的数据集的最新结果。

英文摘要:

Generating natural, diverse, and meaningful questions from images is an essential task for multimodal assistants as it confirms whether they have understood the object and scene in the images properly. The research in visual question answering (VQA) and visual question generation (VQG) is a great step. However, this research does not capture questions that a visually-abled person would ask multimodal assistants. Recently published datasets such as KB-VQA, FVQA, and OK-VQA try to collect questions that look for external knowledge which makes them appropriate for multimodal assistants. However, they still contain many obvious and common-sense questions that humans would not usually ask a digital assistant. In this paper, we provide a new benchmark dataset that contains questions generated by human annotators keeping in mind what they would ask multimodal digital assistants. Large scale annotations for several hundred thousand images are expensive and time-consuming, so we also present an effective way of automatically generating questions from unseen images. In this paper, we present an approach for generating diverse and meaningful questions that consider image content and metadata of image (e.g., location, associated keyword). We evaluate our approach using standard evaluation metrics such as BLEU, METEOR, ROUGE, and CIDEr to show the relevance of generated questions with human-provided questions. We also measure the diversity of generated questions using generative strength and inventiveness metrics. We report new state-of-the-art results on the public and our datasets.
