Visual question answering (VQA) is the task of answering questions about an image. The task assumes an understanding of both the image and the question to provide a natural language answer. VQA has gained popularity in recent years due to its potential applications in a wide range of fields, including robotics, education, and healthcare. In this paper, we focus on knowledge-augmented VQA, where answering the question requires commonsense knowledge, world knowledge, and reasoning about ideas and concepts not present in the image. We propose a multimodal framework that uses language guidance (LG) in the form of rationales, image captions, scene graphs, etc to answer questions more accurately. We benchmark our method on the multi-choice question-answering task of the A-OKVQA, Science-QA, VSR, and IconQA datasets using CLIP and BLIP models. We show that the use of language guidance is a simple but powerful and effective strategy for visual question answering. Our language guidance improves the performance of CLIP by 7.6% and BLIP-2 by 4.8% in the challenging A-OKVQA dataset. We also observe consistent improvement in performance on the Science-QA, VSR, and IconQA datasets when using the proposed language guidances. The implementation of LG-VQA is publicly available at https:// github.com/declare-lab/LG-VQA.

对于图像中的问题，通过使用语言指导（LG）如解释、图像标题、场景图等方面的共识知识、世界知识和理解创意和概念来回答问题更准确；提出了一种多模态框架，使用CLIP和BLIP模型通过A-OKVQA、Science-QA、VSR和IconQA数据集的多选问题回答任务进行了基准测试，语言指导使得CLIP的性能提高了7.6%，BLIP-2的性能提高了4.8%；使用所提出的语言指导在Science-QA、VSR和IconQA数据集上也观察到了持续的性能改进。
