	Exploiting hierarchical discourse structure for review sentiment analysis
	Wang, Fei ; Wu, Yunfang
	2013
英文摘要	The overall sentiment of a text is critically affected by its discourse structure. For the first time, this paper incorporates hierarchical discourse structure into an unsupervised sentiment analysis framework. Experimental results show that by integrating discourse structure, the performance of sentiment analysis is improved by 1.9% (from 85.1% to 87.0%), demonstrating the effectiveness of exploiting discourse structure for sentiment analysis. ? 2013 IEEE.; EI; 0
