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.
