　　Modifiers can affect sentiment orientation.A modifier can change the intensity and polarity of a sentiment word.This paper focuses on the modified polarity.We analyse five hundred comments on goods from the web,and find three features of modifiers which play important roles in sentiment anlysis: intensity,negation and implicit polarity.We also discuss the polarity and intensity of sentiment words with multi-modifiers.Finally we propose a method to calculate the sentiment orientation of the collocations of modifiers and sentiment words.
