Image-Text Joint Learning for Social Images with Spatial Relation Model

الملخص EN

The rapid developments in sensor technology and mobile devices bring a flourish of social images, and large-scale social images have attracted increasing attention to researchers.

Existing approaches generally rely on recognizing object instances individually with geo-tags, visual patterns, etc.

However, the social image represents a web of interconnected relations; these relations between entities carry semantic meaning and help a viewer differentiate between instances of a substance.

This article forms the perspective of the spatial relationship to exploring the joint learning of social images.

Precisely, the model consists of three parts: (a) a module for deep semantic understanding of images based on residual network (ResNet); (b) a deep semantic analysis module of text beyond traditional word bag methods; (c) a joint reasoning module from which the text weights obtained using image features on self-attention and a novel tree-based clustering algorithm.

The experimental results demonstrate the effectiveness of using Flickr30k and Microsoft COCO datasets.

Meanwhile, our method considers spatial relations while matching.
