Dataset Description This is the training partition of the BlEmoRe dataset, released as part of the BlEmoRe Challenge on Blended Emotion Recognition. It includes 2,456 multimodal portrayals of both basic and blended emotions, recorded under controlled studio conditions with synchronized audio and video. A total of 47 actors and actresses participated in the recordings. Each was instructed to express: Basic Emotions Anger, Disgust, Fear, Happiness, Sadness — portrayed in four different intensities (int1–int4) Neutral — portrayed in four distinct but equivalent imagined situations (sit1–sit4); these situations are not ordered or ranked, and are included primarily to increase variability in neutral portrayals Blended Emotions All pairwise combinations of the five basic emotions (excluding neutral) Portrayed in three blend ratios: 50/50: equal salience 70/30: first emotion dominant 30/70: second emotion dominant Expressions were conveyed using facial expressions, body movement, and non-linguistic vocalizations (e.g., sighs, laughs). Participants were instructed to appear naturalistic and avoid exaggerated or stereotypical portrayals. File Format & Naming Convention The dataset is split into five ZIP archives containing raw .mov video files. Each file follows the naming pattern: Basic emotions <video_id>_<emotion>_<intensity_or_situation>_<version> Blended emotions <video_id>_mix_<emotion_1>_<emotion_2>_<version> Description: <video_id>: unique identifier for the actor/actress <emotion>: one of the five basic emotions <intensity_or_situation>: int1–int4 for intensity, sit1–sit4 for neutral context <version>: ver1, ver2, etc. (some portrayals have multiple valid takes) mix: appears only in blended emotion filenames Metadata A metadata file is provided, containing: Filename Emotion(s) and blend ratio Actor/actress gender Suggested validation fold assignment — each fold contains non-overlapping actors/actresses, and the folds are generally balanced by gender.
