AI总结:

本文提出MultiQG-TI方法,通过结合图像描述、OCR提取文本与输入文本,使纯文本问题生成器能够处理多模态输入,并在ScienceQA上以极少参数显著超越ChatGPT。

摘要:

我们研究从包含图像和文本的多模态来源自动生成问题(QG)这一新问题,显著扩展了大多数现有工作仅关注纯文本来源问题生成的范围。我们为这一新问题提出一种简单解决方案,称为MultiQG-TI,它使仅文本的问题生成器能够在文本输入之外处理视觉输入。具体而言,我们利用图像到文本模型和光学字符识别模型分别获得图像的文本描述并提取图像中的任何文本,然后将它们与输入文本一起馈送给问题生成器。我们仅微调问题生成器,同时保持其他组件固定。在具有挑战性的ScienceQA数据集上,我们证明MultiQG-TI显著优于少样本提示的ChatGPT,尽管可训练参数少了一百倍。进一步的分析从经验上证实了视觉和文本信号对于QG的必要性,并展示了各种建模选择的影响。

英文摘要:

We study the new problem of automatic question generation (QG) from multi-modal sources containing images and texts, significantly expanding the scope of most of the existing work that focuses exclusively on QG from only textual sources. We propose a simple solution for our new problem, called MultiQG-TI, which enables a text-only question generator to process visual input in addition to textual input. Specifically, we leverage an image-to-text model and an optical character recognition model to obtain the textual description of the image and extract any texts in the image, respectively, and then feed them together with the input texts to the question generator. We only fine-tune the question generator while keeping the other components fixed. On the challenging ScienceQA dataset, we demonstrate that MultiQG-TI significantly outperforms ChatGPT with few-shot prompting, despite having hundred-times less trainable parameters. Additional analyses empirically confirm the necessity of both visual and textual signals for QG and show the impact of various modeling choices.
