 ## Dataset Structure
 The dataset is released as a single CSV file with 450 rows (one row per video) and 4 core columns, with segment-level annotations stored in structured list format:
-Column Name	Description
-videoID	Unique identifier for each video, corresponding to the original platform's video ID
-segment-level annotation	One-hot encoded labels for 11 harmful categories, with one list per annotated segment in the video
-segment-level timestamp	Start and end timestamps (in mm:ss format) for each annotated harmful segment, with one pair per segment
-contributing modalities	One-hot encoded labels for 3 contributing modalities (visual, textual, auditory), with one list per annotated segment
-Key Dataset Statistics
-Total videos: 450
-Total annotated harmful segments: 1,099
-Video duration range: 3–40 minutes
-Average harmful segment duration: 68.31 seconds
-Harmful categories: 11 fine-grained classes (Information Harm, Verbal Abuse, Hate, Bias, Addiction Harm, Sexual Harm, Physical Harm, Violence, Blood/Gore, Criminal Activity, Danger)
-Contributing modalities: 3 classes (Visual, Textual, Auditory)
