A novel benchmark and dataset are proposed for multi-modal summarization of UI instructional videos, addressing the need for step-by-step executable instructions and key video frames.
We study multi-modal summarization for instructional videos, whose goal is to
provide users an efficient way to learn skills in the form of text instructions
and key video frames. We observe that existing benchmarks focus on generic
semantic-level video summarization, and are not suitable for providing
step-by-step executable instructions and illustrations, both of which are
crucial for instructional videos. We propose a novel benchmark for user
interface (UI) instructional video summarization to fill the gap. We collect a
dataset of 2,413 UI instructional videos, which spans over 167 hours. These
videos are manually annotated for video segmentation, text summarization, and
video summarization, which enable the comprehensive evaluations for concise and
executable video summarization. We conduct extensive experiments on our
collected MS4UI dataset, which suggest that state-of-the-art multi-modal
summarization methods struggle on UI video summarization, and highlight the
importance of new methods for UI instructional video summarization.
