... term–documentin- formation as well as rich sentiment content. The proposed model can leverage both con- tinuous and multi-dimensional sentiment in- formation as well as non -sentiment annota- tions. ... our method performed better than LDA, which models latent topics directly. We extended the unsupervised model to incor- porate sentiment information and showed how this extended mo...
