Dataset Card for VideoXum

Dataset Summary

The VideoXum dataset represents a novel task in the field of video summarization, extending the scope from single-modal to cross-modal video summarization. This new task focuses on creating video summaries that containing both visual and textual elements with semantic coherence. Built upon the foundation of ActivityNet Captions, VideoXum is a large-scale dataset, including over 14,000 long-duration and open-domain videos. Each video is paired with 10 corresponding video summaries, amounting to a total of 140,000 video-text summary pairs.

Languages

The textual summarization in the dataset are in English.

Dataset Fields

• video_id: str a unique identifier for the video.
• duration: float total duration of the video in seconds.
• sampled_frames: int the number of frames sampled from source video at 1 fps with a uniform sampling schema.
• timestamps: List_float a list of timestamp pairs, with each pair representing the start and end times of a segment within the video.
• tsum: List_str each textual video summary provides a summarization of the corresponding video segment as defined by the timestamps.
• vsum: List_float each visual video summary corresponds to key frames within each video segment as defined by the timestamps. The dimensions (3 x 10) suggest that each video segment was reannotated by 10 different workers.
• vsum_onehot: List_bool one-hot matrix transformed from 'vsum'. The dimensions (10 x 83) denotes the one-hot labels spanning the entire length of a video, as annotated by 10 workers.

Annotation Sample

For each video, We hire workers to annotate ten shortened video summaries.
