Semantic Modeling of Textual Relationships in Cross-Modal Retrieval

摘要:

不同模态的特征建模是当前跨模态信息检索研究的一个基本问题。现有的模型通常将文本和图像投影到一个嵌入空间中,其中语义相似的信息将具有较短的距离。纹理关系的语义建模是出了名的困难。在本文中,我们提出了一种方法来建模文本使用的特征图,通过整合多视图的文本关系,包括语义关系,统计共现,和知识库中的先验关系。采用双路径神经网络联合学习信息的多模态表示和跨模态相似性度量。我们使用图卷积网络(GCN)来生成关系感知的文本表示,并使用具有非线性的卷积神经网络(CNN)来进行图像表示。通过距离度量学习来学习跨模态相似性度量。实验结果表明,通过利用文本中丰富的关系语义,我们的模型在两个基准数据集上的准确率分别比最先进的模型高出3.4%和6.3%。

英文摘要:

Feature modeling of different modalities is a basic problem in current research of cross-modal information retrieval. Existing models typically project texts and images into one embedding space, in which semantically similar information will have a shorter distance. Semantic modeling of textural relationships is notoriously difficult. In this paper, we propose an approach to model texts using a featured graph by integrating multi-view textual relationships including semantic relations, statistical co-occurrence, and prior relations in the knowledge base. A dual-path neural network is adopted to learn multi-modal representations of information and cross-modal similarity measure jointly. We use a Graph Convolutional Network (GCN) for generating relation-aware text representations, and use a Convolutional Neural Network (CNN) with non-linearities for image representations. The cross-modal similarity measure is learned by distance metric learning. Experimental results show that, by leveraging the rich relational semantics in texts, our model can outperform the state-of-the-art models by 3.4% and 6.3% on accuracy on two benchmark datasets.
