Abstract
En 中文
Summarization tasks aim to summarize multiple pieces of information into a short description or representative information. A text summarization task summarizes textual information into a short description, whereas an image collection summarization task summarizes an image collection into images or textual representation in which the challenge is to understand the relationship between images. In recent years, scene-graph generation has shown the advantage of describing the visual contexts of a single-image, and incorporating external knowledge into the scene-graph generation model has also given effective directions for unseen single-image scene-graph generation. While external knowledge has been implemented in related work, it is still challenging to use this information efficiently for relationship estimation during the summarization. Following this trend, in this paper, we propose a novel scene-graph-based image-collection summarization model that aims to generate a summarized scene-graph of an image collection. The key idea of the proposed method is to enhance the relation predictor toward relationships between images in an image collection incorporating knowledge graphs as external knowledge for training a model. With this approach, we build an end-to-end framework that can generate a summarized scene graph of an image collection. To evaluate the proposed method, we also build an extended annotated MS-COCO dataset for this task and introduce an evaluation process that focuses on estimating the similarity between a summarized scene graph and ground-truth scene graphs. Traditional evaluation focuses on calculating precision and recall scores, which involve true positive predictions without balancing precision and recall. Meanwhile, the proposed evaluation process focuses on calculating the F-score of the similarity between a summarized scene graph and ground-truth scene graphs, which aims to balance both false positives and false negatives. Experimental results show that using external knowledge to enhance the relation predictor achieves better results than existing methods.
