We explore the novel task of identifying latent attributes in video scenes, such as the mental states of actors, using only large text collections as background knowledge and minimal information about the videos, such as activity and actor types. We formalize the task and a measure of merit that accounts for the semantic relatedness of mental state terms. We develop and test several largely unsupervised information extraction models that identify the mental states of human participants in video
