Image-text matching has been a hot research topic bridging the vision and language areas. It remains challenging because the current representation of image usually lacks global semantic concepts as in its corresponding text caption. To address this issue, we propose a simple and interpretable reasoning model to generate visual representation that captures key objects and semantic concepts of a scene. Specifically, we first build up connections between image regions and perform reasoning with Graph Convolutional Networks to generate features with semantic relationships. Then, we propose to use the gate and memory mechanism to perform global semantic reasoning on these relationship-enhanced features, select the discriminative information and gradually generate the representation for the whole scene. Experiments validate that our method achieves a new state-of-the-art for the image-text matching on MS-COCO and Flickr30K datasets. It outperforms the current best method by 6.8% relatively for image retrieval and 4.8% relatively for caption retrieval on MS-COCO (Recall@1 using 1K test set). On Flickr30K, our model improves image retrieval by 12.6% relatively and caption retrieval by 5.8% relatively (Recall@1). Our code is available at https://github.com/KunpengLi1994/VSRN.

我们提出了一种简单而易于解释的推理模型，用于生成全局场景的主要对象和语义概念的可视化表示，该模型使用图卷积网络进行关联和推理，再使用门和记忆机制进行全局语义推理，选取判别信息并逐渐生成整个场景的表示；实验证明我们的方法在MS-COCO和Flickr30K数据集上取得了相对于最佳方法分别为6.8％和4.8％的图像检索和字幕检索的新的最佳效果，Flickr30K数据集上分别提高了12.6％和5.8％的图像检索和字幕检索。
