Self-contained semantic hypervideos using Web Components

The creation of hypervideos—displayed video streams that contain embedded user-clickable anchors and annotations—is a manual and tedious job, requiring the preparation of assets like still frames, the segmentation of videos in scenes or chapters, and sometimes even the isolation of objects like faces within the video. In this paper, we propose a semi-automated Web-Components-based approach to self-contained hypervideo creation. By self-contained we mean that all necessary intrinsic components of the hypervideo, e.g., still frames, should come from the video itself rather than be included as external assets. Web Components is a set of specifications, which let Web developers apply their HTML, CSS, and JavaScript knowledge to build widgets that can be reused easily and reliably. By leveraging this evolving standard, we obtain a high degree of abstraction, which reduces the burden of creating hypervideos to the familiar task of textually marking them up with HTML elements.
