This paper proposes a generative model that simultaneously detects topics, sentiments, and ratings from review articles. Unlike other sentiment analysis models, our proposal, Joint Sentiment Aspect model (JSA), distinguishes objective and subjective information, for a given item and the corresponding rating, to describe the generative process of each article. For handling these differences, JSA introduces a latent sentiment/aspect class variable into each article and a latent switch variable into each token. These classes allow JSA to project these articles onto a latent space of sentiment/aspect dimensionality. Experiments on review articles show that the proposed model is useful as a generative model.
