The Multimodal Corpus of Sentiment Intensity (CMU-MOSI) dataset is a collection of 2199 opinion video clips. Each opinion video is annotated with sentiment in the range [-3,3]. The dataset is rigorously annotated with labels for subjectivity, sentiment intensity, per-frame and per-opinion annotated visual features, and per-milliseconds annotated audio features.
CMU-MOSI dataset is available through CMU Multimodal Data SDK Github: https://github.com/CMU-MultiComp-Lab/CMU-MultimodalSDK
