Sentiment analysis predicts the presence of positive or negative emotions in a text document. In this paper, we consider higher dimensional extensions of the sentiment concept, which represent a richer set of human emotions.

We investigate the resulting model, compare it to psychological observations, and explore its predictive capabilities.
