OMG-Emotion stands for One-Minute Gradual-Emotional Behavior dataset. The dataset contains 567 emotional videos with an average length of 1 minute, and 7,371 video clips segmented and annotated based on discourse (each discourse has at least 5 independent topics).

The videos were selected using crawler technology, searching based on long-term emotional behaviors such as “monologue,” “audition,” “dialogue,” and “emotional scene.”
