NarSUM workshop

With video capture devices becoming widely popular, the amount of video data generated per day has seen a rapid increase over the past few years. Browsing through hours of video data to retrieve useful information is a tedious and boring task. To address this issue, video summarization has played a crucial role towards making this possible.

Video summarization is a well-researched topic in the multimedia community. However, the focus so far had been limited to creating summary to videos which are short (only a few minutes). This workshop aims to call for researcher on relevant background to focus on novel solution for user-centric narrative summarization of long videos. Specifically, the goal is to provide the users with meaningful information and insights from long input videos, potentially captured from multiple cameras. Since the generated output of any video summarization task will be finally consumed by humans, it is also important to have an element of storytelling, where the resulting summary is presented in the form of a narrative for humans to understand easily. These aspects have not been adequately addressed in the existing literature.

This workshop will also discuss other important aspects of the current video summarization research. For example, what is ‘important’ in a video and how to evaluate the goodness of a created summary is still subjective. Many works are based on human annotated training data where the relevance of each frame of the video is annotated (supervised learning methods), or some works consider the summary to be good if the original video can be well reconstructed (unsupervised methods). However, most of the current works do not explicitly take into account the scene semantics (e.g., scenes, objects, people, actions and relations) happening in the video, which are significant indicators in deciding what is ‘important’ in a video.

    All submissions to this workshop must be original works not under review at any other workshop, conference, or journal. Our workshop will follow the same paper submission guidelines as ACM MM 2022 main conference.
  • Paper format: Submitted papers (.pdf format) must use the ACM Article Template
  • Paper length: Submitted papers may consist of 6 to 8 pages. Up to two additional pages may be added for references. The reference pages must only contain references. Over length papers will be rejected without review. Optionally, you may upload supplementary material that complements your submission (50Mb limit). There is no distinction between long and short papers, but the authors may themselves decide on the appropriate length of their paper.
  • Blinding & review: All papers will undergo the same review process and review period. Submitted papers must conform to the “double-blind” review policy. Accepted papers will be published in the ACM Digital Library.
  • For detailed instructions, please refer to the paper submission instructions at ACM MM 2022 main conference
