Abstract：The word sentiment orientation directly influences the sentiment orientation of higher level linguistic unit, such as the phrase, the sentence, the paragraph and the text. This paper proposes a paradigm word selection method based on the category distinguishing ability of a word and the sentiment word table. In consideration of that a word usually has the same sentiment orientation with its synonyms, we propose a method for word sentiment orientation discriminating based on synonyms. The method can avoid the data sparseness issue in a certain extent. The experiment results indicate that the proposed method is superior to the method based on the object word and paradigm words. Key words computer application; Chinese information processing; word sentiment orientation; paradigm word; relation intensity; synonym
