Abstract:Because of the diversity of network comments, common method of text topic classification can not completely adapt to the orientation identification. To solve this problem,this paper proposed a method of text orientation identification based on semantic feature from the point of view of semantic understanding. Expressed sentiment orientation of original text definitely and distinguished original text more precisely than that without semantic feature because of increasing semantic feature. The experimental results indicate the validity of the method.
