Emotion words have been well used as the most obvious choice as feature in the task of textual emotion recognition and auto- matic emotion lexicon construction. In this work, we explore features for rec- ognizing word emotion. Based on Ren- CECps (an annotated emotion corpus) and MaxEnt (Maximum entropy) model, sev- eral contextual features and their com- bination have been experimented. Then PLSA (probabilistic latent semantic anal- ysis) is used to get semantic feature by clustering words and sentences. The ex- perimental results demonstrate the effec- tiveness of using semantic feature for word emotion recognition. After that, “word emotion components” is proposed to describe the combined basic emotions in a word. A significant performance improvement over contextual and seman- tic ...
