ACM ICMR 2018 Special Session

Social-Media Visual Summarization

When an event occurs in real-life, there may be little information available at first. However, as pictures and textual descriptions about the event arrive, they form an evolving story, which is of critical value for the affected or interested persons. This evolving story corresponds to a semantic topic that can be tracked over time with both textual and visual information from multiple social-media sources (i.e., end-users or online services). Moreover, as social-media sources continue to publish information about the story, it becomes critical to select the most relevant information. Thus, based on all collaborative audio-visual and textual information, one can create summaries or stories of those real-world events.

The Social-media visual stories ICMR special session seeks contributions in the area of visual story creation, with collaborative videos, images and texts available from professional media and social-media users. The challenges in creating such visual timelines are various: alignment of videos and images through sound or timestamps, detection of video intervals of high interest, caption generation for a group of pictures, among others. An overview of such an application is presented in the image below.

The special session also welcomes contributions that address specific real-world use-cases (e.g. news, life-logs, festivals), where the visual and textual domain content provide complementary evidences that push the development of new cross-modal storytelling research. These contributions should use public datasets, e.g. MediaEval, LifeLogs, made available by the authors.
