... to manu- ally label documents with their sentiment orienta- tion and then apply off-the-shelf text classification techniques. However, sentiment is often conveyed with subtle linguistic mechanisms ... sentiment. As with F 0 , one can also use soft sentiment labeling for documents, though our experiments are con- ducted with hard assignments. Therefore, the semi-supervised learning w...
