摘要

话语结构对文本的整体情感有重要影响。本文首次将分层话语结构融入到无监督情感分析框架中。实验结果表明，通过整合话语结构，情感分析的性能提高了1.9%(从85.1%提高到87.0%)，证明了利用话语结构进行情感分析的有效性。

Exploiting Hierarchical Discourse Structure for Review Sentiment Analysis

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.
